Abstract
本發明所提供的離型片係具備有基材及離型層;該離型層係設置於上述基材上,且表面設有由具曲面之單位透鏡複數配置所構成之透鏡部。 The release sheet provided by the present invention includes a base material and a release layer; the release layer is provided on the base material, and a lens portion composed of a plurality of unit lenses with curved surfaces is provided on the surface.
Description
本揭示係關於離型片及樹脂皮革。特別係關於能簡便製造油光經抑制的高光澤感、且配合觀察區域利用光澤感變化顯現出設計性之樹脂皮革的離型片,以及上述顯現設計性的樹脂皮革。 This disclosure relates to release sheets and resin leather. In particular, it relates to a release sheet capable of easily producing a high-gloss feeling with suppressed gloss, and exhibiting design leather with a change in gloss in the observation area, and the above-mentioned resin leather exhibiting design.
合成皮革等樹脂皮革係在表面具剝離性的離型片上,塗佈成為原料的樹脂組成物並使其硬化後,藉由剝離上述離型片便可製造,利用由樹脂組成物所形成的表皮層,便具有類似天然皮革的質感與色澤等。 Resin leather, such as synthetic leather, is applied to a release sheet having a peelable surface, and after the resin composition as a raw material is applied and hardened, it can be manufactured by peeling off the release sheet, using a skin formed from the resin composition The layer has a texture and color similar to natural leather.
近年,針對樹脂皮革要求光學性設計性,為能製造此種樹脂皮革,有針對離型片想盡各種辦法進行研究。例如專利文獻1與2有提案表面設有全像狀微細凹凸形狀的離型片,使用此種離型片所製造的合成皮革,利用對表皮層所賦予的全像狀微細凹凸形狀,便可配合觀察角度顯現出虹色光澤。 In recent years, optical design is required for resin leather. In order to manufacture such resin leather, various methods have been studied for release sheets. For example, in Patent Documents 1 and 2, it is proposed to provide a full-image fine irregularity-shaped release sheet on the surface, and the synthetic leather manufactured using such a release sheet can be made using the full-image fine unevenness imparted to the skin layer. With the observation angle, it shows iridescent luster.
另外,本說明書中,所謂「樹脂皮革」係利用樹脂所形成之模擬天然皮革的皮革,設為合成皮革與人工皮革的統稱。 In addition, in this specification, the "resin leather" refers to leather made of resin that simulates natural leather, and is referred to as synthetic leather and artificial leather.
[專利文獻1]日本專利特開平4-361671號公報 [Patent Document 1] Japanese Patent Laid-Open No. 4-361671
[專利文獻2]日本專利特開2010-253779號公報 [Patent Document 2] Japanese Patent Laid-Open No. 2010-253779
專利文獻1與2所揭示的技術,係針對樹脂皮革雖可利用光澤色之變化提升設計性,但另一方面,要求不要依賴光澤色之變化,而是利用對應觀察區域產生之光澤度高低變化(光澤感變化)而顯現設計性的樹脂皮革,具體而言,在某觀察角度範圍內(作為觀察區域),能檢視到呈現樹脂皮革原本色澤,且帶高光澤感,但在此外的其他觀察區域則不會檢視到此種光澤感之設計性的樹脂皮革。又,若欲提高光澤感,則表面會因強光量而出現刺眼感覺的油光,導致呈現出與樹脂皮革原本光澤不同的光澤感。所以,針對樹脂皮革的設計性亦要求抑制油光的高光澤感,期待能製造具有該等設計性樹脂皮革的離型片。 The technologies disclosed in Patent Documents 1 and 2 aim to improve the designability of resin leather by using the change of gloss color, but on the other hand, it is required not to rely on the change of gloss color but to use the change in gloss level corresponding to the observation area (Change in gloss) The design of resin leather, specifically, within a certain viewing angle range (as an observation area), can be seen to show the original color of the resin leather and have a high gloss, but in other observations The design resin leather of this kind of gloss will not be seen in the area. In addition, if the gloss is to be improved, the surface will have a dazzling oil shine due to the amount of strong light, resulting in a glossiness different from the original gloss of resin leather. Therefore, the design of resin leather also requires a high gloss feeling to suppress oil shine, and it is expected that a release sheet having such design resin leather can be manufactured.

The release layer is provided on the above substrate, Moreover, the surface is provided with a lens part composed of a plurality of unit lenses with curved surfaces.
針對本實施形態的離型片,參照圖進行說明。圖1(a)與圖2(a)所示係本實施形態離型片一例及另一例的概略立體示意圖,圖1(b)與圖2(b)所示係圖1(a)與圖2(a)中的X-X線剖視圖。離型片10係具備有基材1與離型層2。該離型層2係設置於基材1上,且表面設有由具曲面之單位透鏡3a複數配置所構成之透鏡部3。 The release sheet of this embodiment will be described with reference to the drawings.

FIG. 2 shows an example of a concave curved surface shape in which the unit lens 3a is recessed into the surface of the release layer 2. In FIGS. 1 and 2, the lens portion 3 has a microlens array shape.
根據本實施形態的離型片,因為離型層表面設有由具曲面之單位透鏡複數配置所構成之透鏡部,因而可簡便地製造表面設有由所需單位透鏡形狀複數配置所構成之透鏡形狀部的樹脂皮革。然後,利用本實施形態離型片所獲得的樹脂皮革,藉由具備上述透鏡形狀部,便可調整在樹脂皮革表面所生成反射光的散射分佈,可呈現油光經抑制的高光澤感,且配合觀察區域能顯現出由光澤感變化所產生之設計性。 According to the release sheet of this embodiment, since the surface of the release layer is provided with a lens portion composed of a complex arrangement of unit lenses with curved surfaces, it is possible to easily manufacture a lens provided with a complex configuration of the desired unit lens shape on the surface Resin leather in the shape part. Then, the resin leather obtained by the release sheet of this embodiment can adjust the scattering distribution of the reflected light generated on the surface of the resin leather by providing the lens-shaped portion described above, and can exhibit a high-gloss feeling with suppressed gloss, and can be combined The observation area can show the design produced by the change of gloss.
此處,針對本實施形態離型片藉由具有上述構成,所獲得樹脂皮革便能顯現上述設計性的理由進行說明如下。 Here, the reason why the release sheet according to the present embodiment has the above-mentioned structure and the obtained resin leather can express the above-mentioned designability will be described below.
若樹脂皮革接觸到光,樹脂皮革的表面便會產生依與入射角相同角度反射的光成分(鏡面反射成分)、以及朝無規方向反射並廣範圍擴散的光成分(擴散反射成分)。 When the resin leather comes into contact with light, the surface of the resin leather generates light components (specular reflection components) that reflect at the same angle as the incident angle, and light components that reflect in a random direction and diffuse widely (diffuse reflection components).
為提高樹脂皮革的光澤度,一般係採取使表面成為平滑面而增加鏡面反射成分比例的手法。但是,若採此種手法,因為在樹脂皮革表面所產生反射光中的鏡面反射成分會直接進入觀察者的眼睛,導致樹脂皮革亦會產生因表面的強烈光亮而造成油光,造成顯現出不同於樹脂皮革原本光澤的光澤感。又,此時,引發鏡面反射的方向被限定於狹窄的角度區域內,因而樹脂皮革能檢視光澤感的觀察區域亦受局限。 In order to improve the glossiness of resin leather, it is generally adopted to make the surface smooth and increase the proportion of the specular reflection component. However, if this method is adopted, because the specular reflection component in the reflected light generated on the surface of the resin leather will directly enter the observer's eyes, the resin leather will also produce oil shine due to the intense light of the surface, causing it to appear different Resin leather has a lustrous luster. In addition, at this time, the direction in which the specular reflection is caused is limited to a narrow angle area, so the observation area where the resin leather can check the glossiness is also limited.
另一方面,若對樹脂皮革的表面利用浮雕加工、噴砂、鍍敷等施行表面處理而賦予無規的微細凹凸形狀,因在樹脂皮革表面所產生反射光中的擴散反射成分比例會增加,因而可抑制油光發生。此時,因為擴散反射係依廣範圍產生,因而可檢視樹脂皮革光澤感的觀察區域便較平滑面時更廣區域。 On the other hand, if the surface of the resin leather is subjected to surface treatment by relief processing, sand blasting, plating, etc. to give random fine irregularities, the proportion of diffuse reflection components in the reflected light generated on the surface of the resin leather will increase, so Can inhibit the occurrence of shine. At this time, since the diffuse reflection system is generated in a wide range, the observation area where the glossiness of the resin leather can be inspected is wider than when it is smooth.
但是,若擴散反射成分的比例變大,便會導致光澤度降低,且會因擴散反射成分與鏡面反射成分的混合而導致樹脂皮革被檢視時呈現偏白色調。 However, if the proportion of the diffuse reflection component is increased, the gloss will be reduced, and the resin leather will appear off-white when inspected due to the mixture of the diffuse reflection component and the specular reflection component.
此種光澤感差異、及可檢視高光澤感區域的寬窄,推定係因從所需角度入射至樹脂皮革之光之的散射光強度非等向性、及擴散角大小所造成。 This difference in gloss and the width of the high-gloss area can be inspected, presumably due to the anisotropy of the scattered light intensity of the light incident on the resin leather from the desired angle and the size of the diffusion angle.
此處,散射光強度的非等向性係可依照散射光強度分佈對散射角的斜率程度進行說明。又,擴散角係可從散射光強度分佈對散射角進行定義。擴散角係如圖3所示,由在將散射角(θ)設為X軸、散射光強度(L)設為Y軸的散射光強度分佈曲線Px、Py中,散射光強度L成為最大散射光強度Lmax之二分之一的2個散射角θ1(Px)、 θ1(Py)及θ2(Px)、θ2(Py)之差(θ2-θ1)的半值寬FWHM(Px)、FWHM(Py)所定義。例如若成為最大散射光強度Lmax之二分之一的散射角(θ)係在θ1=-10°至θ2=+10°範圍內,擴散角便成為20°。另外,相關散射光強度的測定方法,容後詳述。 Here, the anisotropy of the scattered light intensity can be explained according to the scattered light intensity distribution to the degree of the slope of the scattering angle. In addition, the diffusion angle system can define the scattering angle from the scattered light intensity distribution. The diffusion angle system is shown in FIG. 3, and the scattered light intensity L becomes the maximum scattering in the scattered light intensity distribution curves Px and Py with the scattering angle (θ) as the X axis and the scattered light intensity (L) as the Y axis. The half-value width of the difference (θ 2 -θ 1 ) between the two scattering angles θ 1 ( Px ), θ 1(Py) and θ 2(Px) and θ 2(Py) which is half of the light intensity L max Defined by FWHM(Px) and FWHM(Py). For example, if the scattering angle (θ) that is one-half of the maximum scattered light intensity L max is in the range of θ 1 =-10° to θ 2 =+10°, the diffusion angle becomes 20°. In addition, the measurement method of the related scattered light intensity will be described in detail later.
由平滑面所產生的反射光因為大多係鏡面反射成分,因而如圖4(a)所示,散射光強度分佈曲線P會具有急遽的斜率,散射光強度的非等向性較小。又,此時,因為成為最大散射光強度Lmax之二分之一的散射角θ範圍較小,因而所計算出的擴散角FWHM亦變小。另一方面,由無規的微細凹凸形狀面所產生之反射光,因為大多係擴散反射成分,因而如圖4(b)所示,散射光強度分佈曲線P的斜率平滑,散射光強度的非等向性較大。又,此時,因為成為最大散射光強度Lmax之二分之一的散射角θ範圍較大,因而所計算出的擴散角FWHM亦變大。 Since the reflected light generated by the smooth surface is mostly a specular reflection component, as shown in FIG. 4(a), the scattered light intensity distribution curve P has a sharp slope, and the anisotropy of the scattered light intensity is small. In addition, at this time, since the range of the scattering angle θ which is one-half of the maximum scattered light intensity L max is small, the calculated diffusion angle FWHM also becomes small. On the other hand, since the reflected light generated from the random fine uneven surface is mostly diffuse reflection component, as shown in FIG. 4(b), the slope of the scattered light intensity distribution curve P is smooth, and the scattered light intensity is not The isotropy is greater. In addition, at this time, since the range of the scattering angle θ which is half of the maximum scattered light intensity L max is large, the calculated diffusion angle FWHM also becomes large.
即,散射光強度分佈曲線的斜率越急遽,則散射光強度的非等向性越小,樹脂皮革的光澤感越高。另一方面,擴散角的範圍越寬,則能檢視樹脂皮革光澤感的觀察區域越廣域。 That is, the steeper the slope of the scattered light intensity distribution curve, the smaller the anisotropy of the scattered light intensity, and the higher the glossiness of the resin leather. On the other hand, the wider the range of the diffusion angle, the wider the observation area where the glossiness of the resin leather can be inspected.
利用本實施形態離型片所獲得之樹脂皮革,藉由轉印上述離型片表面上所具備設有複數之曲面的單位透鏡及其集合體的透鏡部,便成為表面具備有具曲面之複數之單位透鏡形狀、及其集合體的透鏡形狀部。然後,由樹脂皮革的透鏡形狀部所產生之反射光,可呈現具備有由平滑面所造成的光學特性、與由微細凹凸形狀面所造成的光學特性雙方特長的散射分佈。 The resin leather obtained by using the release sheet of the present embodiment, by transferring the unit lens provided with a plurality of curved surfaces on the surface of the release sheet and the lens portion of its assembly, the surface is provided with a plurality of curved surfaces The unit lens shape and the lens shape portion of its assembly. Then, the reflected light generated by the lens-shaped portion of the resin leather can exhibit a scattering distribution having both the optical characteristics caused by the smooth surface and the optical characteristics caused by the fine uneven surface.
即,在透鏡形狀部所產生的反射光係如圖4(c)所示,雖散射光強度分佈曲線P具有急遽的斜率,散射光強度的非等向性較小,但因為成為最大散射光強度Lmax之二分之一的散射角θ範圍較大,因而所計算出的擴散角FWHM變大。 That is, the reflected light generated in the lens shape portion is as shown in FIG. 4(c). Although the scattered light intensity distribution curve P has a sharp slope, the anisotropy of the scattered light intensity is small, but because it becomes the maximum scattered light The range of the scattering angle θ of the half of the intensity L max is large, so the calculated diffusion angle FWHM becomes large.
所以,由本實施形態的離型片所獲得之樹脂皮革,能檢視光澤感的觀察區域便成為廣域。又,上述樹脂皮革係在上述觀察區域位於擴散角範圍內之時,能顯現出油光經抑制的高光澤感;另一方面,若上述觀察區域偏離擴散角範圍,則光澤感會急遽降低。 Therefore, the resin leather obtained from the release sheet of this embodiment has a wide viewing area where the glossiness can be inspected. In addition, the resin leather system can exhibit a high gloss feeling in which the gloss is suppressed when the observation area is within the diffusion angle range; on the other hand, if the observation area deviates from the diffusion angle range, the gloss feeling may be sharply reduced.
依此,由本實施形態的離型片所獲得之樹脂皮革,因為利用表面的透鏡形狀部調整反射光的散射分佈,因而呈現油光經抑制的光澤感,且配合觀察區域能顯現出由光澤感變化所產生之設計性。 According to this, the resin leather obtained from the release sheet of this embodiment adjusts the scattering distribution of the reflected light by the lens shape portion on the surface, so that it exhibits a lustrous sense of suppression of the oily gloss, and the change of the luster feel can appear in conjunction with the observation area The resulting design.
本實施形態的離型片係藉由設計:在離型層表面上所具備的複數之單位透鏡之曲面形狀、單位透鏡的配置態樣、及其集合體的透鏡部,所獲得樹脂皮革便可呈現所需之散射分佈。 The release sheet of this embodiment can be obtained by designing: the curved surface shape of a plurality of unit lenses provided on the surface of the release layer, the arrangement of the unit lens, and the lens portion of its assembly, to obtain resin leather Present the desired scattering distribution.
另外,針對使用本實施形態離型片所獲得之樹脂皮革呈現的散射分佈,容在後述「B.樹脂皮革」項中說明。 In addition, the scattering distribution exhibited by the resin leather obtained by using the release sheet of this embodiment will be described later in the section "B. Resin leather".
本說明書中,散射光強度及散射光強度分佈曲線係可依照以下方法進行測定及描繪。散射光強度係使用三維變角分光測色系統(GCMS-13型、村上色彩技術研究所股份有限公司製),朝對象面依入射角0°(即鉛直方向)入射光,在受光角度於-60°~60°範圍內、變角間隔1°條件下,分別針對各散射角測定散射光強度。然後,藉由將散射角設為X軸、散射光強度設為Y軸,針對散射光強度對各 散射角的值進行描點,便可描繪出散射光強度分佈曲線。 In this specification, the scattered light intensity and the scattered light intensity distribution curve can be measured and plotted according to the following method. The intensity of the scattered light is a three-dimensional variable-angle spectrophotometric color measurement system (GCMS-13 type, manufactured by Murakami Color Technology Research Institute Co., Ltd.), and the incident light is incident on the object surface at an incident angle of 0° (that is, in the vertical direction). The scattered light intensity was measured for each scattering angle within the range of 60° to 60° and at variable angle intervals of 1°. Then, by setting the scattering angle to the X axis and the scattered light intensity to the Y axis, the When the value of the scattering angle is traced, the scattered light intensity distribution curve can be drawn.
擴散角係從所獲得散射光強度分佈曲線中,藉由計算出屬於散射光強度成為最大散射光強度二分之一之散射角差的半值寬便可求得。 The diffusion angle can be obtained from the obtained scattered light intensity distribution curve by calculating the half-value width of the difference of the scattering angle that the scattered light intensity becomes one-half of the maximum scattered light intensity.
本實施形態的離型片中,當構成透鏡部的複數之單位透鏡對上述離型層的表面呈凸形狀的情況(即如圖1所示,從上述離型層表面朝靠上述基材側的背後側呈突出之凸形狀情況),所獲得樹脂皮革成為具有相對於表面朝內側凹陷的凹形狀單位透鏡形狀。另一方面,當構成透鏡部的複數單位透鏡係相對於上述離型層表面呈凹形狀的情況(即如圖2所示,從上述離型層表面朝上述基材側呈凹陷形狀的情況),所獲得樹脂皮革成為具有突出表面的凸形狀單位透鏡形狀。 In the release sheet of this embodiment, when a plurality of unit lenses constituting the lens portion have a convex shape to the surface of the release layer (ie, as shown in FIG. 1, from the surface of the release layer toward the base material side The back side of the case has a convex convex shape), and the obtained resin leather has a unit lens shape having a concave shape recessed toward the inside with respect to the surface. On the other hand, when the plural unit lens constituting the lens portion has a concave shape with respect to the surface of the release layer (ie, as shown in FIG. 2, a concave shape is formed from the surface of the release layer toward the substrate side) The resin leather obtained has a convex unit lens shape with a protruding surface.
本實施形態離型片的單位透鏡係不管為凹形狀或凸形狀,所獲得樹脂皮革的單位透鏡形狀之凹凸朝向及焦點位置(即各單位透鏡形狀的焦點)僅有位於樹脂皮革的內部或外部的差異而已,不管何種情況,利用單位透鏡形狀的曲面,根據上述原理均可調整反射光的散射分佈,所獲得樹脂皮革可顯現出油光經抑制的高光澤感、及配合觀察區域產生光澤感變化。 The unit lens of the release sheet of this embodiment is not only concave or convex, but the concave and convex orientation and focal position of the unit lens shape of the obtained resin leather (that is, the focus of each unit lens shape) is only located inside or outside the resin leather The difference is that in any case, the curved surface of the unit lens shape can be used to adjust the scattering distribution of the reflected light according to the above principle. The obtained resin leather can show a high gloss feeling with suppressed oil shine, and a gloss feeling in conjunction with the observation area. Variety.
以下,針對本實施形態離型片的各構成進行說明。 Hereinafter, each configuration of the release sheet according to this embodiment will be described.
本實施形態離型片的離型層係形成(配置)於上述基材上,且表 面設有由具曲面之單位透鏡複數配置所構成之透鏡部。 The release layer system of the release sheet of this embodiment is formed (arranged) on the above-mentioned substrate, and the surface The surface is provided with a lens portion composed of a plurality of unit lens arrangements with curved surfaces.
以下,針對離型層的表面中,亦有將設有透鏡部之一面稱為「(離型層之)透鏡部形成面」進行說明的情況。 In the following, the surface on which the lens portion is provided is also referred to as the “surface of the lens portion (of the release layer)” on the surface of the release layer.

When the unit lens has a convex shape with respect to the lens portion forming surface of the release layer, the focal point of the unit lens is located inside the release layer or the substrate. On the other hand, when the unit lens has a concave shape with respect to the lens portion forming surface of the release layer, the focal point of the unit lens is located outside the release layer on the side of the release layer.
尤其本實施形態中,上述單位透鏡較佳係相對於上述離型層的表面呈凸形狀。即,單位透鏡的焦點較佳係位於上述離型層或上述基材的內部。單位透鏡設為具有從離型層表面朝外側突出的凸形狀,利用本實施形態離型片所製造的樹脂皮革,便可在其表面上塑造出凹形狀的單位透鏡形狀。所以,所獲得樹脂皮革不僅可利用在其表面上所塑造的透鏡形狀部顯現出所需設計性,且相較於經塑造為凸形狀單位透鏡形狀的情況下,可達材料量減少的緣故所致。 Especially in this embodiment, the unit lens preferably has a convex shape with respect to the surface of the release layer. That is, the focal point of the unit lens is preferably located inside the release layer or the substrate. The unit lens has a convex shape protruding outward from the surface of the release layer, and the resin leather manufactured by the release sheet of this embodiment can form a unit lens shape with a concave shape on the surface. Therefore, the obtained resin leather can not only show the required design using the lens shape part molded on the surface, but also can reduce the amount of material compared with the case where the lens shape is formed into a convex shape unit lens To.
上述單位透鏡係可為球面透鏡、亦可為非球面透鏡。此種單位透鏡具體係可例示如:微透鏡、柱面透鏡、菲涅耳透鏡、複曲面透 鏡(toric lens)等。 The unit lens system may be a spherical lens or an aspheric lens. Specific examples of such unit lenses are: microlenses, cylindrical lenses, Fresnel lenses, toric lenses Mirror (toric lens) and so on.
單位透鏡的平面觀形狀並無特別的限定,可配合單位透鏡的種類再行適當設計。例如:圓形、長方形或正方形等四角形、多角形、三角形等。 The planar shape of the unit lens is not particularly limited, and can be appropriately designed according to the type of unit lens. For example: quadrilateral, polygon, triangle, etc., such as circle, rectangle or square.
再者,單位透鏡厚度方向的截面形狀(以下簡稱「截面形狀」),係如圖5(a)所例示,相對於單位透鏡3a的中心軸Y可為對稱形,亦可如圖5(b)所例示,相對於單位透鏡3a的中心軸Y成為非對稱形,可配合針對利用本實施形態離型片所獲得樹脂皮革要求的設計性再行適當設計。 In addition, the cross-sectional shape in the thickness direction of the unit lens (hereinafter referred to as "cross-sectional shape") is illustrated in FIG. 5(a), and may be symmetrical with respect to the central axis Y of the unit lens 3a, as shown in FIG. 5(b ), the center axis Y of the unit lens 3a is asymmetrical, and can be appropriately designed in accordance with the design requirements for the resin leather obtained by using the release sheet of this embodiment.
例如若複數單位透鏡的截面形狀全部均為對稱形狀的話,則所獲得樹脂皮革中,利用各單位透鏡形狀所顯現的反射光之散射分佈亦具有對稱性。即,所獲得樹脂皮革中,因為由透鏡形狀部所產生反射光的散射分佈成為對稱,因而若從相對於單位透鏡形狀中心軸具對稱關係的二方向檢視,便會呈現相同的光澤感。 For example, if all the cross-sectional shapes of the plurality of unit lenses are symmetrical, then in the obtained resin leather, the scattering distribution of the reflected light exhibited by each unit lens shape also has symmetry. That is, in the obtained resin leather, since the scattering distribution of the reflected light generated by the lens shape portion becomes symmetrical, when viewed from two directions having a symmetric relationship with respect to the central axis of the unit lens shape, the same glossiness will be exhibited.
另一方面,若複數之單位透鏡的截面形狀呈非對稱形狀,則所獲得樹脂皮革中,利用各單位透鏡形狀所顯現的反射光之散射分佈亦能具非對稱性。即,所獲得樹脂皮革中,因為由透鏡形狀部所產生反射光的散射分佈成為非對稱,因而若從相對於單位透鏡形狀中心軸具對稱關係的二方向檢視,其中一方向呈高光澤感,相對的另一方向則呈低光澤感,便可使所顯現的設計性不同。 On the other hand, if the cross-sectional shape of a plurality of unit lenses has an asymmetric shape, in the obtained resin leather, the scattering distribution of the reflected light exhibited by each unit lens shape can also be asymmetric. That is, in the obtained resin leather, since the scattering distribution of the reflected light generated by the lens shape portion becomes asymmetric, when viewed from two directions having a symmetric relationship with respect to the central axis of the unit lens shape, one of the directions has a high gloss feeling, The opposite direction shows a low gloss, which can make the design different.
另外,所謂「單位透鏡的截面形狀」係指單位透鏡從寬度方向觀看到的形狀;而所謂「單位透鏡的中心軸」係指通過單位透鏡之寬度正中央(圖5中的O)之軸。相關樹脂皮革的透鏡形狀中心軸亦同,指通過透鏡形狀寬度正中央的軸。 In addition, the "cross-sectional shape of the unit lens" refers to the shape of the unit lens viewed from the width direction; and the "center axis of the unit lens" refers to the axis passing through the center of the width of the unit lens (O in FIG. 5). The central axis of the lens shape of the related resin leather is also the same, referring to the axis passing through the center of the lens shape width.
單位透鏡的寬度係只要針對利用本實施形態離型片所獲得樹脂皮革的表面,能調整反射光之散射分佈的大小便可,例如較佳係300μm以下、尤其更佳係100μm以下、特佳係80μm以下。又,上述寬度較佳係30μm以上。若單位透鏡的寬度大於上述範圍,利用本實施形態離型片所獲得樹脂皮革表面上具有的單位透鏡形狀便容易看到,會有損及上述樹脂皮革設計性的情況。另一方面,若單位透鏡的寬度小於上述範圍,則儘管單位透鏡及由其所形成樹脂皮革表面的單位透鏡形狀所造成功能幾乎沒有變化,但仍會有提高製造難度的情況。 The width of the unit lens can be adjusted as long as the surface of the resin leather obtained by using the release sheet of this embodiment can adjust the size of the scattering distribution of the reflected light. For example, it is preferably 300 μm or less, more preferably 100 μm or less, and the ultra good series. Below 80μm. In addition, the width is preferably 30 μm or more. If the width of the unit lens is larger than the above range, the shape of the unit lens on the surface of the resin leather obtained by using the release sheet of this embodiment is easy to see, which may impair the designability of the resin leather. On the other hand, if the width of the unit lens is smaller than the above range, although the function of the unit lens and the unit lens shape of the surface of the resin leather formed by the unit lens hardly change, the manufacturing difficulty may be increased.
所謂「單位透鏡寬度」係如圖1(b)與圖2(b)所例示,指單位透鏡根部部分的寬度W。例如微透鏡,當單位透鏡的平面圖形狀呈圓形之情況,單位透鏡的寬度便指圓形的直徑。又,如柱面透鏡,當單位透鏡的平面圖形狀呈四角形之情況,單位透鏡的寬度便指單位透鏡的短邊方向長度。 The “unit lens width” is illustrated in FIGS. 1(b) and 2(b), and refers to the width W of the root portion of the unit lens. For example, in the case of a micro lens, when the shape of the unit lens is circular, the width of the unit lens refers to the diameter of the circle. Also, like a cylindrical lens, when the unit lens has a rectangular shape in plan view, the width of the unit lens refers to the length of the unit lens in the short side direction.
所謂「單位透鏡的根部部分」係當相鄰單位透鏡未隔開間隔配置時,便指從其中一單位透鏡輪廓切換為另一單位透鏡輪廓的部分;當相鄰單位透鏡有隔開間隔配置時,便指從平坦面切換為單位透鏡輪廓的部分。上述根部部分係在圖1(b)與圖2(b)中依C標示的 部分。當相鄰單位透鏡間的間隔並非平坦而是呈曲面的情況等,可將單位透鏡延伸方向的垂直截面中,在單位透鏡根部附近的輪廓線轉折點,設為單位透鏡根部。 The so-called "root part of unit lens" refers to the part where the contour of one unit lens is switched to the contour of another unit lens when adjacent unit lenses are not spaced apart; when adjacent unit lenses are spaced apart , Refers to the part that switches from a flat surface to a unit lens outline. The above-mentioned roots are marked by C in Figure 1(b) and Figure 2(b) section. When the interval between adjacent unit lenses is not flat but curved, etc., the vertical section of the unit lens in the extension direction may be the turning point of the contour line near the root of the unit lens as the root of the unit lens.
單位透鏡的厚度係只要利用本實施形態離型片所獲得樹脂皮革的表面中,能調整反射光之散射分佈的大小便可,可配合單位透鏡的寬度與形狀等再行適當調整。 The thickness of the unit lens may be adjusted as long as the size of the scattering distribution of the reflected light can be adjusted on the surface of the resin leather obtained by the release sheet of the present embodiment, and can be appropriately adjusted according to the width and shape of the unit lens.
具體而言,單位透鏡的厚度較佳係10μm~150μm範圍內、更佳係15μm~150μm範圍內、其中特佳係15μm~40μm範圍內。若單位透鏡的厚度大於上述範圍,便大於離型片的離型層厚度,因而會有無法轉印的情況;另一方面,若小於上述範圍,則儘管單位透鏡及由其所形成樹脂皮革表面的單位透鏡形狀所造成之功能幾乎沒有變化,但仍會有提高製造難度的情況。 Specifically, the thickness of the unit lens is preferably in the range of 10 μm to 150 μm, more preferably in the range of 15 μm to 150 μm, and particularly in the range of 15 μm to 40 μm. If the thickness of the unit lens is greater than the above range, it is greater than the thickness of the release layer of the release sheet, so there may be cases where transfer is impossible; on the other hand, if it is less than the above range, although the unit lens and the surface of the resin leather formed by it The function caused by the shape of the unit lens is almost unchanged, but there will still be circumstances that increase the difficulty of manufacturing.
此處,所謂「單位透鏡厚度」,若為凸形狀單位透鏡,便指從根部部分至最頂部的長度;若為凹形狀單位透鏡,便指從根部部分至最底部的長度,在圖1(b)與圖2(b)中依D標示的部分。 Here, the "unit lens thickness" refers to the length from the root to the top if it is a convex unit lens; if it is a concave unit lens, it refers to the length from the root to the bottom, as shown in Figure 1( b) The part marked with D in Figure 2(b).
單位透鏡係只要在利用本實施形態離型片所獲得樹脂皮革中,具有能調整反射光之散射分佈的曲面便可,可配合單位透鏡的形狀等再行適當設定。所謂單位透鏡具有曲面,係只要單位透鏡的曲率半徑在15μm~150μm範圍內(15μm以上且150μm以下)便可,其中較佳係15μm~40μm範圍內(15μm以上且40μm以下)。若單位透鏡的截面形狀呈非對稱形狀,則最好曲率最小部分的曲率半徑在上述範圍內。 The unit lens system only needs to have a curved surface capable of adjusting the scattering distribution of the reflected light in the resin leather obtained by using the release sheet of this embodiment, and can be appropriately set according to the shape of the unit lens and the like. The unit lens has a curved surface as long as the radius of curvature of the unit lens is in the range of 15 μm to 150 μm (15 μm or more and 150 μm or less), and preferably it is in the range of 15 μm to 40 μm (15 μm or more and 40 μm or less). If the cross-sectional shape of the unit lens is an asymmetric shape, it is preferable that the radius of curvature of the smallest curvature portion is within the above range.
上述單位透鏡的表面係只要至少其中一部分具有上述曲率半徑所表示的曲面便可,亦涵蓋上述表面其中一部分為平坦面。 The surface of the unit lens only needs to have at least a part of it having a curved surface represented by the radius of curvature, and it also covers that a part of the surface is a flat surface.
上述單位透鏡的寬度、厚度、曲率半徑係利用雷射顯微鏡、AFM、SEM等取得截面輪廓便可測量。例如使用雷射顯微鏡(OLYMPUS公司製OLS4000),利用撮影模式的雷射顯微鏡觀察取得高度數據,再利用測定模式顯示出截面輪廓,並配合游標便可計算出單位透鏡的寬度、厚度、曲率半徑。 The width, thickness, and radius of curvature of the above unit lens can be measured using a laser microscope, AFM, SEM, etc. to obtain a cross-sectional profile. For example, using a laser microscope (OLS4000 manufactured by OLYMPUS), using a laser microscope in the imaging mode to obtain height data, and then using the measurement mode to display the cross-sectional profile, and with the cursor can calculate the width, thickness, and radius of curvature of the unit lens.
透鏡部係由配置複數之單位透鏡而成。 The lens unit is formed by arranging plural unit lenses.
上述透鏡部中,所配置的複數之單位透鏡可全部均為相同形狀及相同尺寸,亦可由不同形狀或尺寸的複數種單位透鏡混雜配置。 In the above lens section, the plurality of unit lenses arranged may all have the same shape and the same size, or a plurality of unit lenses of different shapes or sizes may be mixedly arranged.
再者,當由不同形狀或尺寸的複數種單位透鏡混雜配置時,不同種類的單位透鏡可具一定規則性配置、亦可無規則性配置。 Furthermore, when a plurality of unit lenses of different shapes or sizes are mixedly arranged, the unit lenses of different types may have a certain regular configuration, or may be arranged irregularly.
所配置的複數單位透鏡係可於所有厚度方向的截面形狀均具有對稱形,亦可為其中一部分含有截面形狀具非對稱形的單位之透鏡。 The arranged plural unit lens may have a symmetrical cross-sectional shape in all thickness directions, or may be a lens in which a part of the unit has an asymmetrical cross-sectional shape.
針對所配置的單位透鏡個數等,係可對應藉由本實施形態相關之離型片所獲得之樹脂皮革的用途與設計性再行適當選擇。 The number of unit lenses arranged, etc., can be appropriately selected according to the use and design of the resin leather obtained by the release sheet related to this embodiment.
上述透鏡部中,可為複數之單位透鏡全部均相對於離型層的透鏡部形成面呈凸形狀,亦可為複數之單位透鏡全部均相對於離型層的透鏡部形成面呈凹形狀。尤其在本實施形態中,最好複數單位透 鏡全部均相對於離型層的透鏡部形成面呈凸形狀。即,複數之上述單位透鏡的焦點最好位於上述離型層或上述基材的內部。針對此項之理由係如前述。 In the above lens portion, all of the plural unit lenses may have a convex shape with respect to the lens portion forming surface of the release layer, or all of the plural unit lenses may have a concave shape with respect to the lens portion forming surface of the release layer. Especially in this embodiment, it is better All the mirrors have a convex shape with respect to the lens portion forming surface of the release layer. That is, the focal points of the plural unit lenses are preferably located inside the release layer or the substrate. The reasons for this are as described above.
上述透鏡部中,複數單位透鏡係以鄰接單位透鏡彼此間的根部彼此間可以相鄰接方式而未設置間隔地配置,亦可鄰接單位透鏡彼此間隔開依所需間隔配置,可配合上述單位透鏡的尺寸、形成方法、對利用本實施形態離型片所獲得樹脂皮革要求的設計性等再行適當選擇。通常最好複數之單位透鏡未隔開間隔地配置。 In the above-mentioned lens part, the plural unit lenses are arranged such that the roots of adjacent unit lenses can be arranged adjacent to each other without an interval, or adjacent unit lenses can be spaced apart according to a required interval, which can be matched with the unit lens The size, the forming method, and the design required for the resin leather obtained by using the release sheet of this embodiment are appropriately selected. In general, it is preferable that plural unit lenses are arranged without an interval.
當鄰接單位透鏡彼此間有隔開間隔地配置時,上述間隔最好在滿足單位透鏡寬度及配置間距的範圍內適當設定。 When the adjacent unit lenses are arranged with an interval therebetween, the above-mentioned interval is preferably appropriately set within a range satisfying the unit lens width and arrangement pitch.
單位透鏡的配置間距係只要能調節利用本實施形態離型片所獲得之樹脂皮革表面中的反射光散射分佈便可,尤其最好係上述樹脂皮革的單位透鏡形狀係不易被目視到的大小。例如上述配置間距最好設為單位透鏡寬度的1倍以上且5倍以下,尤其更佳係1倍以上且2倍以下、特佳係1倍。若配置間距大於上述範圍,因為離型層表面上的平坦部分變多,因而會有所獲得樹脂皮革的光學特性降低之情況。又,設計上較難將配置間距設為小於上述範圍。 The arrangement pitch of the unit lenses may be adjusted as long as the reflected light scattering distribution on the surface of the resin leather obtained by the release sheet of the present embodiment can be adjusted, and it is particularly preferable that the unit lens shape of the resin leather is not easily visible. For example, the above-mentioned arrangement pitch is preferably set to be 1 times or more and 5 times or less per unit lens width, particularly preferably 1 times or more and 2 times or less, and particularly preferably 1 times. If the arrangement pitch is larger than the above range, because there are more flat parts on the surface of the release layer, the optical characteristics of the resin leather may be reduced. In addition, it is difficult to design to make the arrangement pitch smaller than the above range.
所謂「單位透鏡的配置間距」係在圖1(b)與圖2(b)中係依P標示的部分。在鄰接單位透鏡彼此間未設計間隔配置的情況,單位透鏡的配置間距便與單位透鏡的寬度相同。 The so-called “arrangement distance of unit lens” is the part indicated by P in FIGS. 1(b) and 2(b). When the adjacent unit lenses are not spaced apart from each other, the arrangement pitch of the unit lenses is the same as the width of the unit lenses.
上述透鏡部的複數之單位透鏡之配置態樣係在利用本實施形 態離型片所獲得之樹脂皮革的表面,配置成能調整反射光之散射分佈的配置態樣前提下,其餘並無特別的限定,可配合單位透鏡的形狀等適當設計為一維排列或二維排列。 The arrangement of the plural unit lenses of the lens section described above is The surface of the resin leather obtained by the state release sheet is configured to adjust the scattering distribution of the reflected light, and the rest is not particularly limited. It can be designed as a one-dimensional arrangement or two according to the shape of the unit lens. Dimensional arrangement.
此處,所謂「一維排列」係例如圖6(a)及(b)所例示,指在離型層2的透鏡部形成面上,由複數之單位透鏡3a(柱面透鏡)朝一維方向排列的配置態樣。由此種配置態樣構成的透鏡部稱為「扁豆狀透鏡」(lenticular lens)。另外,圖6(a)所示係本實施形態離型片另一例的概略立體示意圖,圖6(b)所示係圖6(a)中的X-X線剖視圖。 Here, the “one-dimensional arrangement” is exemplified in FIGS. 6( a) and (b ), for example, and refers to the one-dimensional direction in which the unit lens 3 a (cylindrical lens) of the plural unit lens is formed on the lens portion forming surface of the release layer 2. Arranged configuration. The lens portion composed of this arrangement is called a "lenticular lens". In addition, FIG. 6(a) is a schematic perspective schematic view of another example of the release sheet of the present embodiment, and FIG. 6(b) is a cross-sectional view taken along line X-X in FIG. 6(a).
另一方面,所謂「二維排列」係例如圖1及圖2所例示,指在離型層2的透鏡部形成面上,由複數之單位透鏡3a(微透鏡)朝二維方向(透鏡部形成面的縱橫方向)排列的配置態樣。由此種配置態樣構成的透鏡部稱為「微透鏡陣列」。又,依二維排列形成單位透鏡時,柱面透鏡亦可朝二維方向呈圖案狀排列。 On the other hand, the "two-dimensional arrangement" is exemplified in FIGS. 1 and 2, for example, and refers to the unit lens 3 a (microlens) facing the two-dimensional direction (lens section) on the lens section forming surface of the release layer 2. The arrangement of the surface is arranged in the vertical and horizontal directions). The lens portion configured in this arrangement is called a "microlens array." Furthermore, when the unit lenses are formed in a two-dimensional arrangement, the cylindrical lenses may also be arranged in a pattern in a two-dimensional direction.
單位透鏡的二維排列態樣並無特別的限定,例如圖1與圖2所例示的正方格排列,亦可為鋸齒狀排列、六方稠密排列等。 The two-dimensional arrangement of the unit lens is not particularly limited. For example, the square lattice arrangement illustrated in FIGS. 1 and 2 may be a zigzag arrangement or a hexagonal dense arrangement.
另外,單位透鏡的配置間距亦可不同,且不同的間距亦可具一定規則性、亦可不具規則性。 In addition, the arrangement pitch of the unit lenses may also be different, and different pitches may or may not have certain regularity.
上述離型層通常係利用樹脂形成。上述樹脂係只要可塑造所需的單位透鏡,且當製造使用本實施形態離型片的樹脂皮革時,可輕易剝離樹脂皮革的樹脂便可,例如熱可塑性樹脂、硬化樹脂。所謂「硬化樹脂」係指對熱硬化性樹脂施行加熱而硬化的樹脂(熱硬化樹脂),或藉由對游離輻射線硬化樹脂照射游離輻射線而硬化的樹 脂(游離輻射線硬化樹脂)。又,游離輻射線硬化樹脂係可舉例如:紫外線硬化樹脂、電子束硬化樹脂。 The release layer is usually formed using resin. The above-mentioned resin system only needs to be able to mold the desired unit lens, and when manufacturing the resin leather using the release sheet of this embodiment, the resin of the resin leather can be easily peeled off, such as thermoplastic resin and hardened resin. The term "cured resin" refers to a resin (thermosetting resin) that is cured by heating a thermosetting resin, or a tree that is cured by irradiating free radiation curing resin with free radiation Grease (free radiation hardening resin). In addition, the radiation-radiation-curable resin system includes, for example, ultraviolet-curing resin and electron beam-curing resin.
此處,所謂「游離輻射線」係指電磁波或荷電粒子束中,具有能將分子聚合或交聯之能量量子(energy quantum)的放射線,例如紫外線、電子束,此外尚可例如:X線、γ線等電磁波;α線、離子束等荷電粒子束(ion beam)。其中,較佳係紫外線、電子束。 Here, the "free radiation" refers to an electromagnetic wave or a charged particle beam that has energy quantum (energy quantum) radiation capable of polymerizing or cross-linking molecules, such as ultraviolet rays and electron beams. Electromagnetic waves such as gamma rays; ion beams such as alpha rays and ion beams. Among them, ultraviolet rays and electron beams are preferred.
熱可塑性樹脂係可使用例如:聚甲基丙烯酸甲酯等丙烯酸系樹脂;聚乙烯、聚丙烯、聚甲基戊烯等聚烯烴系樹脂;聚對苯二甲酸乙二酯、聚對苯二甲酸丁二酯等聚酯系樹脂;聚苯乙烯等苯乙烯系樹脂;聚氯乙烯等乙烯系樹脂;聚碳酸酯樹脂;聚矽氧樹脂;聚乙烯醇;日本專利特開2015-27811號公報等所揭示的共聚合體等習知公知的樹脂。 For the thermoplastic resin system, for example: acrylic resins such as polymethyl methacrylate; polyolefin resins such as polyethylene, polypropylene, and polymethylpentene; polyethylene terephthalate, polyterephthalic acid Polyester resins such as butadiene; styrene resins such as polystyrene; vinyl resins such as polyvinyl chloride; polycarbonate resins; polysiloxane resins; polyvinyl alcohol; Japanese Patent Laid-Open No. 2015-27811, etc. Known conventional resins such as the disclosed interpolymers.
熱硬化性樹脂係可舉例如:不飽和聚酯、三聚氰胺、環氧、聚酯(甲基)丙烯酸酯、胺甲酸乙酯(甲基)丙烯酸酯、環氧(甲基)丙烯酸酯、多醚(甲基)丙烯酸酯、多元醇(甲基)丙烯酸酯、三聚氰胺(甲基)丙烯酸酯、三系丙烯酸酯等。 Examples of thermosetting resins include unsaturated polyester, melamine, epoxy, polyester (meth)acrylate, urethane (meth)acrylate, epoxy (meth)acrylate, and polyether (Meth)acrylate, polyol (meth)acrylate, melamine (meth)acrylate, tri Department of acrylate.
游離輻射線硬化性樹脂係可舉例如:胺酯系樹脂、環氧系樹脂、酯系樹脂、丙烯酸系樹脂、丙烯酸酯共聚合體等。 Examples of the free radiation curable resin system include urethane resins, epoxy resins, ester resins, acrylic resins, and acrylate copolymers.
其中,上述樹脂較佳係熱可塑性樹脂、更佳係聚丙烯。理由係可對離型層表面精度佳地賦予所需的單位透鏡,且當使用本實施形態離型片製造樹脂皮革時,可使從樹脂皮革的剝離性變得良好。 Among them, the resin is preferably a thermoplastic resin and more preferably a polypropylene. The reason is that the required unit lens can be imparted to the surface of the release layer with good accuracy, and when the release sheet is used to produce resin leather in this embodiment, the peelability from the resin leather can be improved.
離型層係可為透明、亦可為半透明或不透明。又,上述離型層亦可被著色。 The release layer system can be transparent, semi-transparent or opaque. In addition, the release layer may be colored.
離型層的厚度係只要可在表面設置所需形狀之單位透鏡、及屬於其集合體之透鏡部的厚度便可,例如1μm~200μm範圍內、其中較佳係20μm~50μm範圍內。若離型層的厚度大於上述範圍,則會有離型層形成時所使用的材料量及費用、以及離型片整體的製造成本增加之情況;另一方面,若小於上述範圍,則會有無法設置所需形狀單位透鏡及屬於其集合體之透鏡部的情況。另外,所謂「離型層的厚度」係在圖1(b)與圖2(b)中以T標示的部分。 The thickness of the release layer may be as long as the unit lens of a desired shape and the lens portion belonging to the aggregate can be provided on the surface, for example, within a range of 1 μm to 200 μm, and preferably within a range of 20 μm to 50 μm. If the thickness of the release layer is greater than the above range, the amount of materials and costs used in forming the release layer and the overall manufacturing cost of the release sheet may increase; on the other hand, if it is less than the above range, there will be The unit lens of the required shape and the lens part belonging to the aggregate cannot be provided. In addition, the so-called "thickness of the release layer" is the portion marked with T in FIGS. 1(b) and 2(b).
再者,在離型層的透鏡部形成面上亦可設有剝離層。理由係可提升樹脂皮革製造時的剝離性。剝離層的材料係可舉例如聚矽氧系樹脂、氟系樹脂,將該等樹脂塗佈於離型層的透鏡部形成面上,經乾燥便可形成。 Furthermore, a release layer may be provided on the lens portion forming surface of the release layer. The reason is that the peelability during resin leather production can be improved. Examples of the material system of the peeling layer include polysiloxane resin and fluorine resin. These resins are applied to the lens portion forming surface of the release layer and can be formed by drying.
剝離層的厚度係只要不會損及離型層之透鏡部形成面形狀的厚度便可,較佳係例如0.1μm~3μm左右。理由係若在上述範圍以下會有剝離力嫌不足的可能性,另一方面,若在上述範圍以上會導致形狀乖離變大。 The thickness of the peeling layer may be a thickness that does not impair the shape of the lens portion forming surface of the release layer, and is preferably about 0.1 μm to 3 μm, for example. The reason is that if it is below the above range, the peeling force may be insufficient, and if it is above the above range, the shape deviation may become larger.
再者,亦可取代設置剝離層,改為使離型層含有離型劑。離型劑係可舉例如習知公知的材料,可使用例如日本專利特開2015-039847號公報所揭示的離型劑。 Furthermore, instead of providing a peeling layer, the release layer may contain a release agent. Examples of the release agent system include conventionally known materials, and for example, the release agent disclosed in Japanese Patent Laid-Open No. 2015-039847 can be used.
離型層係光朝上述透鏡部(透鏡部形成面)從鉛直方向(入射角0°)入射時,在相對於散射角的散射光強度分佈曲線中,散射光強度為20%時的散射角與散射光強度為80%時的散射角之差之絶對值S(80-20),較佳係4°以上且15°以下、其中更佳S(80-20)係4°以上且8°以下。 When the light from the release layer system enters the lens portion (the lens portion forming surface) from the vertical direction (incident angle 0°), the scattering angle at the scattered light intensity distribution curve with respect to the scattering angle is 20% in the scattered light intensity distribution curve with respect to the scattering angle The absolute value S (80-20) of the difference between the scattering angle and the scattered light intensity at 80% is preferably 4° or more and 15° or less, and more preferably S (80-20) is 4° or more and 8° the following.
藉由S(80-20)值在上述範圍內,散射光強度分佈曲線便具有急遽的斜率,反射光的散射光強度非等向性變小。所以,使用本實施形態離型片所獲得樹脂皮革的散射光強度分佈曲線亦呈現同樣的斜率,散射光強度的非等向性變小。藉此,上述樹脂皮革便可顯現出所需的設計性。 When the S (80-20) value is within the above range, the scattered light intensity distribution curve has a sharp slope, and the scattered light intensity anisotropy of the reflected light becomes smaller. Therefore, the scattered light intensity distribution curve of the resin leather obtained using the release sheet of this embodiment also exhibits the same slope, and the anisotropy of the scattered light intensity becomes smaller. With this, the above-mentioned resin leather can exhibit the required design.
若上述離型層的S(80-20)值大於上述範圍,散射光強度分佈曲線的斜率變為平緩,散射光強度的非等向性變大。所以,相關使用本實施形態離型片獲得的樹脂皮革亦同樣地,因為散射光強度的非等向性變大,因擴散反射造成的影響變大之緣故,因而高光澤設計性的顯現趨於困難。另一方面,若上述離型層的S(80-20)小於上述範圍,便較難塑造所需形狀的透鏡部。 If the S (80-20) value of the release layer is greater than the above range, the slope of the scattered light intensity distribution curve becomes gentle, and the anisotropy of the scattered light intensity becomes large. Therefore, the resin leather obtained by using the release sheet of the present embodiment is also similar, because the anisotropy of the scattered light intensity becomes larger and the influence due to diffuse reflection becomes larger, so the appearance of high gloss design tends to be difficult. On the other hand, if S (80-20) of the release layer is smaller than the above range, it is difficult to shape the lens portion of the desired shape.
另外,圖7所示係說明散射光強度分佈曲線中,散射光強度為20%時的散射角、與散射光強度為80%時的散射角的差之說明圖。 In addition, FIG. 7 is an explanatory diagram illustrating the difference between the scattering angle when the scattered light intensity is 20% and the scattering angle when the scattered light intensity is 80% in the scattered light intensity distribution curve.
再者,上述離型層在透鏡部(透鏡部形成面)的光擴散角較佳係大於5°且在90°以下、其中更佳係10°以上且60°以下。若擴散角超過上述範圍,則因擴散反射造成的影響變大,另一方面,若擴散角低於上述範圍,則因鏡面反射造成的影響變大,因而使用本實施形態離型片獲得的樹脂皮革不易顯現所需設計性。所謂「在透鏡部(透 鏡部形成面)的光擴散角」,即光朝透鏡部(透鏡部形成面)從鉛直方向(入射角0°)入射時的擴散角。 Furthermore, the light diffusion angle of the lens part (lens part forming surface) of the release layer is preferably greater than 5° and 90° or less, and more preferably 10° or more and 60° or less. If the diffusion angle exceeds the above range, the influence due to diffuse reflection becomes larger. On the other hand, if the diffusion angle is lower than the above range, the influence due to specular reflection becomes larger. Therefore, the resin obtained by the release sheet of the present embodiment is used. Leather is not easy to show the required design. The so-called "in the lens part (through The light diffusion angle of the mirror portion forming surface), that is, the diffusion angle when light enters the lens portion (lens portion forming surface) from the vertical direction (incidence angle 0°).
本實施形態離型片的基材係支撐著離型層。 The base material of the release sheet of this embodiment supports the release layer.
上述基材係在能形成離型層之前提下,其餘並無特別的限定,可例如一般樹脂皮革製造用離型片或加工紙(process paper)所使用的習知公知材質之基材。具體係可舉例如:不織布、織布、或該等的積層體等。可使用例如:牛皮紙、高級紙、塗料紙等紙;聚對苯二甲酸乙二酯、聚萘二甲酸乙二酯等聚酯;各種尼龍等聚醯胺;聚丙烯等樹脂薄膜;合成紙、金屬箔、織布、不織布等。該等係可單獨使用、或適當積層使用。 The above-mentioned substrate is mentioned before the release layer can be formed, and the rest is not particularly limited. For example, it can be a substrate of a conventionally known material used in a release sheet or process paper for general resin leather production. Specific examples include nonwoven fabrics, woven fabrics, and laminates of these. Can be used for example: Kraft paper, high-grade paper, coated paper and other paper; polyethylene terephthalate, polyethylene naphthalate and other polyesters; various nylon and other polyamides; polypropylene and other resin films; synthetic paper, Metal foil, woven cloth, non-woven cloth, etc. These systems can be used alone or appropriately stacked.
其中,就從使用本實施形態離型片製造樹脂皮革時,不易發生熱劣化、且與離型層間之密接性高的觀點,上述基材較佳係紙。 Among them, the base material is preferably paper from the viewpoints that when the resin leather is manufactured using the release sheet of the present embodiment, thermal degradation is unlikely to occur and the adhesion to the release layer is high.
再者,於上述基材為樹脂薄膜的情況,樹脂薄膜所使用的樹脂亦可與上述形成離型層的樹脂相同。此情況,基材與離型層亦可成一體。 Furthermore, when the substrate is a resin film, the resin used for the resin film may be the same as the resin forming the release layer. In this case, the substrate and the release layer can also be integrated.
相關上述基材的厚度並無特別的限定,可配合基材的材質等再行適當設定,較佳係設定於例如50μm~200μm範圍內。 The thickness of the above-mentioned base material is not particularly limited, and can be appropriately set in accordance with the material of the base material, etc. It is preferably set in the range of, for example, 50 μm to 200 μm.
針對上述基材靠離型層側之一面,在提升與離型層間之密接性目的下,亦可施行例如電暈放電處理、臭氧處理等易接著性處理、 或底漆塗佈等表面處理。 For the surface of the base material close to the release layer side, for the purpose of improving the adhesion between the release layer and the release layer, easy adhesion treatment such as corona discharge treatment, ozone treatment, etc., Or surface treatment such as primer coating.
本實施形態的離型片係至少設有在表面上已形成有透鏡部的離型層及基材,但視需要亦可設有任意的層。 The release sheet of this embodiment is provided with at least a release layer and a substrate on which the lens portion has been formed, but any layer may be provided as necessary.
例如基材表面為非平滑的情況,為了能均勻地形成離型層,亦可在基材與離型層之間設置平滑性提升層。平滑性提升層係可例如由日本專利特開2002-086622號公報等所揭示般組成構成的平滑性提升層、或黏粒層(clay court layer)等。 For example, when the surface of the substrate is non-smooth, in order to form the release layer uniformly, a smoothness improvement layer may be provided between the substrate and the release layer. The smoothness improvement layer system may be, for example, a smoothness improvement layer composed of a composition disclosed in Japanese Patent Laid-Open No. 2002-086622 or the like, or a clay court layer.
再者,亦可在基材與離型層之間設置密接層。理由係可提升基材與離型層間之密接性。底漆層的材料係可例如氟系塗佈劑、矽烷偶合劑等。 Furthermore, an adhesion layer may be provided between the base material and the release layer. The reason is to improve the adhesion between the substrate and the release layer. The material system of the primer layer may be, for example, a fluorine-based coating agent or a silane coupling agent.
本實施形態的離型片亦可離型層與基材呈一體。所謂「離型層與基材呈一體」,係如圖8(a)、(b)所例示,離型層2與基材1由同一材料形成的單層5。構成上述單層的材料係可例如在「1.離型層」項中所說明的材料。 In the release sheet of this embodiment, the release layer may be integrated with the substrate. The so-called "the release layer is integrated with the substrate" is a single layer 5 formed of the same material as the release layer 2 and the substrate 1 as illustrated in Figs. 8(a) and (b). The material constituting the above-mentioned single layer can be, for example, the material described in the item “1. Release layer”.
相關離型層與基材呈一體的離型片中之透鏡部等,係與前所說明的內容同樣,因而在此不再贅述。 The lens part and the like in the release sheet in which the relevant release layer is integrated with the base material are the same as those described above, and therefore will not be described here.
本實施形態的離型片係利用表面所設置的單位透鏡及屬於其集合體的透鏡部,而對由透鏡部形成面所反射光的散射分佈進行調 整。 The release sheet of the present embodiment uses the unit lens provided on the surface and the lens portion belonging to the assembly thereof to adjust the scattering distribution of the light reflected by the lens portion forming surface whole.
本實施形態的離型片係透鏡部形成面的S(80-20)及光擴散角,較佳呈現上述「1.離型層」項中所說明的S(80-20)及光擴散角。相關此項理由因為在上述「1.離型層」項中已有說明,故不再贅述。 S (80-20) formed in the surface of the release sheet based lens unit according to the present embodiment and the light diffusing angle, preferably exhibit the above "1. the release layer" as described in item S (80-20) and the light diffusing angle . The reason for this is already explained in the above item "1. Release layer", so it will not be repeated here.
本實施形態離型片之其他態樣,係表面設有具備複數個具曲面之單位透鏡的透鏡部,且上述單位透鏡的曲率半徑係15μm以上且150μm以下。 In another aspect of the release sheet of this embodiment, a lens portion having a plurality of unit lenses with curved surfaces is provided on the surface, and the radius of curvature of the unit lens is 15 μm or more and 150 μm or less.
本實施形態的離型片,因為表面所設置的透鏡部係由具既定範圍內曲率半徑的單位透鏡複數設置所構成,因而可使上述S(80-20)及各自的擴散角分別在既定範圍內。藉此,利用本實施形態離型片所獲得的樹脂皮革,能調整表面所產生之反射光的散射分佈,故能呈現油光經抑制的高光澤感,且配合觀察區域可顯現出由光澤感變化所產生之設計性。 In the release sheet of this embodiment, since the lens portion provided on the surface is composed of a plurality of unit lens complexes with a radius of curvature within a predetermined range, the above S (80-20) and their respective diffusion angles can be respectively within a predetermined range Inside. In this way, the resin leather obtained by the release sheet of the present embodiment can adjust the scattering distribution of the reflected light generated on the surface, so that it can exhibit a high gloss feeling with suppressed oil shine, and the change of gloss feeling can be displayed in conjunction with the observation area The resulting design.
相關上述其他態樣的離型片詳細內容,係如同前所說明。 The details of the release films related to the other aspects mentioned above are as described above.
本實施形態離型片的製造方法係在基材其中一表面上所形成的離型層表面上,在能賦予所需形狀之複數單位透鏡及屬於其集合體之透鏡部的方法前提下,其餘並無特別的限定,可配合離型層形成時所使用的材料再行適當選擇。 The manufacturing method of the release sheet of the present embodiment is on the surface of the release layer formed on one surface of the base material, on the premise of a method that can give a plurality of unit lenses of a desired shape and a lens portion belonging to the assembly thereof, the rest There is no particular limitation, and the material used when forming the release layer may be appropriately selected.
例如若離型層形成用組成物中所含的樹脂係游離輻射線硬化樹脂,則藉由在基材其中一表面上塗佈離型層形成用組成物後,再 將已形成相當於所需單位透鏡形狀之凹部或凸部的轉印版,壓抵於塗佈層,並照射游離輻射線而使之硬化,便可形成表面具有透鏡部的離型層。 For example, if the resin-based free radiation hardening resin contained in the composition for the release layer is formed by coating the composition for the release layer on one surface of the substrate, then A transfer plate that has formed concave or convex portions corresponding to the desired unit lens shape is pressed against the coating layer and irradiated with free radiation to harden it, thereby forming a release layer having a lens portion on the surface.
另一方面,若離型層形成用組成物中所含的樹脂係熱可塑性樹脂,則可採取一邊將屬於離型層形成用組成物的樹脂擠出層壓於基材表面上,一邊壓抵已形成相當於所需單位透鏡形狀之凹部或凸部的轉印版,而形成表面設有透鏡部之離型層的方法。又,亦可採取在基材其中一表面上,塗布離型層形成用組成物後,再將已形成相當於所需單位透鏡形狀之凹部或凸部的轉印版,加熱按押於塗佈層,而形成表面設有透鏡部之離型層的方法等。 On the other hand, if the resin-based thermoplastic resin contained in the composition for forming the release layer, the resin belonging to the composition for forming the release layer may be pressed against the substrate surface while being pressed against A transfer plate corresponding to a concave or convex portion corresponding to a desired unit lens shape has been formed, and a method of forming a release layer having a lens portion on the surface is formed. Alternatively, after applying the composition for forming the release layer on one surface of the substrate, the transfer plate having the concave or convex portions corresponding to the desired unit lens shape may be heated and pressed onto the coating Layer, and a method of forming a release layer provided with a lens portion on the surface.
本實施形態的離型片係頗適用為合成皮革或人工皮革等樹脂皮革製造時的加工剝離紙(process release paper),惟併不僅侷限於此。本實施形態離型片係除樹脂皮革製造用的離型片用途之外,尚可使用為例如橡膠片、碳薄片、其他樹脂片或薄膜的製造模。 The release sheet system of the present embodiment is quite suitable as process release paper when manufacturing resin leather such as synthetic leather or artificial leather, but it is not limited to this. The release sheet of the present embodiment can be used as a production die for, for example, rubber sheets, carbon sheets, other resin sheets, or films in addition to the use of release sheets for resin leather production.
本發明一實施形態的樹脂皮革(以下亦稱「本實施形態的樹脂皮革」)係具備有支撐層及樹脂表皮層。該樹脂表皮層係設置於上述支撐層上,且表面設有由具曲面之單位透鏡形狀複數配置所構成的透鏡形狀部。 The resin leather of one embodiment of the present invention (hereinafter also referred to as "resin leather of this embodiment") is provided with a support layer and a resin skin layer. The resin skin layer is provided on the support layer, and the surface is provided with a lens-shaped portion composed of a plurality of unit lens shapes with curved surfaces arranged in plural.
相關本實施形態的樹脂皮革,參照圖式進行說明。圖9(a)與圖 10(a)所示係本實施形態樹脂皮革一例及另一例的概略立體示意圖,圖9(b)與圖10(b)所示係圖9(a)與圖10(a)中的X-X線剖視圖。樹脂皮革20係具備有支撐層11與樹脂表皮層12。該樹脂表皮層12係配置於支撐層11上,且表面設有由具曲面之單位透鏡形狀13a複數配置所構成的透鏡形狀部13。 The resin leather of this embodiment will be described with reference to the drawings. Figure 9(a) and figure 10(a) is a schematic perspective view showing an example and another example of resin leather of the present embodiment, and FIG. 9(b) and FIG. 10(b) are the lines XX in FIGS. 9(a) and 10(a). Sectional view. The resin leather 20 is provided with a support layer 11 and a resin skin layer 12. The resin skin layer 12 is disposed on the support layer 11, and the surface is provided with a lens shape portion 13 composed of a plurality of curved unit lens shapes 13 a arranged in plural.

An example of a concave curved surface shape in which the unit lens shape 13a is recessed on the surface of the resin leather layer 12 shown in FIG. The lens shape part 13 of FIGS. 9 and 10 has a microlens array shape.
根據本實施形態的樹脂皮革,在樹脂皮革的樹脂表皮層表面上,設有由具曲面之單位透鏡形狀複數配置所構成的透鏡形狀部,因為利用上述透鏡形狀部調整反射光的散射分佈,故可呈抑制油光的高光澤感,且配合觀察區域能顯現出由光澤感變化所產生之設計性。 According to the resin leather of the present embodiment, the surface of the resin skin layer of the resin leather is provided with a lens shape portion composed of a plurality of unit lens shapes with curved surfaces. Because the lens shape portion adjusts the scattering distribution of the reflected light, It has a high gloss feeling that suppresses the shine, and it can show the design due to the change of gloss feeling in conjunction with the observation area.
以下,針對本實施形態的樹脂皮革,依各構成進行說明。 Hereinafter, the resin leather of this embodiment will be described according to each configuration.
本實施形態樹脂皮革的樹脂表皮層係形成(配置)於上述支撐層上,且表面設有由具曲面之單位透鏡形狀複數配置所構成之透鏡形狀部。 The resin skin layer of the resin leather of this embodiment is formed (arranged) on the above-mentioned support layer, and the surface is provided with a lens-shaped portion composed of a plurality of curved unit lens shapes arranged in plural.
上述樹脂表皮層係使用為樹脂皮革的表皮,具有類似天然皮革的質感與色澤。 The resin skin layer is made of resin leather, and has a texture and color similar to natural leather.
相關樹脂表皮層的單位透鏡形狀及透鏡形狀部,係與「A.離型片」項中說明的離型層所具備有單位透鏡及透鏡部同樣,故在此不再贅述。 The unit lens shape and lens shape portion of the relevant resin skin layer are the same as the unit lens and lens portion provided in the release layer described in the section of “A. Release sheet”, so they will not be repeated here.
其中,本實施形態如圖10所例示,複數上述單位透鏡形狀較佳係相對於上述樹脂表皮層的表面呈凹形狀。理由係藉由將複數單位透鏡形狀設為凹形狀,便可利用透鏡形狀部顯現出所需的設計性,且相較於具備凸形狀單位透鏡形狀的情況下,可達降低樹脂表皮層所使用的材料量。 In this embodiment, as shown in FIG. 10, it is preferable that the plurality of unit lens shapes have a concave shape with respect to the surface of the resin skin layer. The reason is that by setting the complex unit lens shape to a concave shape, the required designability can be exhibited by the lens shape portion, and the use of the resin skin layer can be reduced compared to the case where the unit lens shape having a convex shape is provided The amount of material.
樹脂表皮層所使用的樹脂係可適用一般合成皮革或人工皮革製造時所使用的剛性樹脂,例如尼龍、聚胺酯、聚氯乙烯等。樹脂係可單獨使用1種、亦可併用2種以上。 The resin system used for the resin skin layer can be applied to rigid resins generally used in the manufacture of synthetic leather or artificial leather, such as nylon, polyurethane, and polyvinyl chloride. One type of resin type may be used alone, or two or more types may be used in combination.
再者,上述樹脂表皮層亦可含有可塑劑、安定劑、著色劑等添加劑。 Furthermore, the resin skin layer may contain additives such as plasticizers, stabilizers, colorants and the like.
樹脂表皮層的厚度係在能設置所需單位透鏡形狀及屬於其集合體之透鏡形狀部的厚度前提下,其餘並無特別的限定,可配合用途等再行適當設計。 The thickness of the resin skin layer is based on the premise that the required unit lens shape and the thickness of the lens shape part belonging to the aggregate can be provided, and the rest is not particularly limited, and can be appropriately designed according to the use and the like.
本實施形態樹脂皮革的支撐層係支撐著樹脂表皮層。 The support layer of the resin leather of this embodiment supports the resin skin layer.
支撐層係例如:木綿、麻、羊毛等天然纖維;縲縈、醋酸酯等 再生或半合成纖維;由聚醯胺、聚酯、聚丙烯腈、聚乙烯醇、聚烯烴等合成纖維的纖維所構成織布、不織布、網布、紙、聚酯或聚烯烴的樹脂薄膜;金屬板、金屬箔、玻璃板、玻璃纖維織布等,可配合樹脂皮革的種類與用途,從一般合成皮革或人工皮革所使用的材料中適當選擇。 Support layer system such as: natural fibers such as kapok, hemp, wool, etc.; rayon, acetate, etc. Recycled or semi-synthetic fibers; woven cloth, non-woven cloth, mesh cloth, paper, polyester or polyolefin resin film composed of fibers of synthetic fibers such as polyamide, polyester, polyacrylonitrile, polyvinyl alcohol, and polyolefin; Metal plates, metal foils, glass plates, fiberglass woven fabrics, etc., can be selected from materials generally used for synthetic leather or artificial leather in accordance with the types and uses of resin leather.
支撐層的厚度係在能支撐樹脂表皮層的厚度前提下,其餘並無特別的限定。 The thickness of the support layer is based on the premise that it can support the thickness of the resin skin layer, and the rest is not particularly limited.
本實施形態的樹脂皮革係藉由表面所設置的透鏡形狀部,而調整反射光之散射光強度的非等向性、擴散角大小等反射光的散射分佈,因而可呈油光經抑制的高光澤感,且配合觀察區域能顯現出由光澤感變化所產生之設計性。 The resin leather of this embodiment adjusts the scattering distribution of the reflected light such as the anisotropy of the scattered light intensity of the reflected light and the size of the diffusion angle by the lens-shaped portion provided on the surface, so that it can exhibit high gloss with suppressed oil shine Sense, and the observation area can show the design caused by the change of gloss.
本實施形態的樹脂皮革亦可為樹脂表皮層與支撐層呈一體。所謂「樹脂表皮層與支撐層呈一體」係指離型層與基材係由同一材料形成的單層。構成上述單層的材料係可例如「1.樹脂表皮層」項中所說明的材料。 In the resin leather of this embodiment, the resin skin layer and the support layer may be integrated. The so-called "resin skin layer and support layer are integrated" means that the release layer and the base material are a single layer formed of the same material. The material constituting the above-mentioned single layer may be, for example, the material described in the item “1. Resin skin layer”.
相關樹脂表皮層與支撐層呈一體的樹脂皮革中之透鏡形狀部等,係與前已說明的內容同樣,故在此不再贅述。 The lens-shaped portion and the like in the resin leather in which the relevant resin skin layer and the support layer are integrated are the same as those previously explained, so they will not be repeated here.
本實施形態的樹脂皮革較佳係由透鏡形狀部所產生反射光的散射光強度之非等向性較小。所謂「散射光強度的非等向性較小」,即指「散射光強度分佈曲線具有急遽的斜率」。 In the resin leather of this embodiment, it is preferable that the anisotropy of the scattered light intensity of the reflected light generated by the lens shape portion is small. The so-called "the anisotropy of the scattered light intensity is small" means that the "scattered light intensity distribution curve has a sharp slope".
具體而言,光朝樹脂皮革的透鏡形狀部(具備透鏡形狀部之一面)從鉛直方向(入射角0°)入射時,在相對於散射角的散射光強度分佈曲線中,散射光強度為20%時的散射角、與散射光強度為80%時的散射角的差之絶對值S(80-20),較佳係4°以上且15°以下、其中更佳S(80-20)係4°以上且8°以下。S(80-20)值越大,則散射光強度分佈曲線的斜率越平緩,散射光強度的非等向性越大,因而由擴散反射所造成的影響越大。所以,樹脂皮革的光澤度降低,成為偏白色澤,較難顯現高光澤的設計性。另一方面,若S(80-20)小於上述範圍,則樹脂皮革表面較難具有所需形狀的透鏡形狀部。 Specifically, when light is incident from the vertical direction (incident angle 0°) toward the lens-shaped portion of the resin leather (a surface provided with the lens-shaped portion), the scattered light intensity distribution curve with respect to the scattering angle is 20 The absolute value of the difference between the scattering angle at% and the scattering angle at 80% of the scattered light intensity S (80-20) is preferably 4° or more and 15° or less, and S (80-20) is more preferable Above 4° and below 8°. The larger the value of S (80-20) , the smoother the slope of the scattered light intensity distribution curve and the greater the anisotropy of the scattered light intensity, so the greater the impact caused by diffuse reflection. Therefore, the glossiness of the resin leather is reduced and becomes whiter, making it difficult to exhibit high-gloss design. On the other hand, if S (80-20) is smaller than the above range, it is difficult for the surface of the resin leather to have a lens-shaped portion of a desired shape.
再者,本實施形態的樹脂皮革係能在所需觀察區域顯示出高光澤性。所謂「樹脂皮革能檢視到高光澤性的觀察區域」係指「樹脂皮革的透鏡形狀部之擴散角範圍內」。 Furthermore, the resin leather system of this embodiment can show high gloss in a desired observation area. The so-called "observation area where resin leather can be observed with high glossiness" refers to "within the diffusion angle range of the lens shape portion of resin leather".
具體而言,上述樹脂皮革的透鏡形狀部(具備透鏡形狀部之一面)的光擴散角較佳係大於5°且在90°以下、其中更佳係10°以上且60°以下。若樹脂皮革的透鏡形狀部之擴散角超過上述範圍,則因擴散反射所造成的影響會變大,會有不易獲得高光澤感的情況。另一方面,若擴散角小於上述範圍,則因鏡面反射所造成的影響會變大,會有油光較高光澤感更容易被檢視到的情況。透鏡形狀部的光擴散角,即光朝透鏡形狀部從鉛直方向(入射角0°)入射時的擴散角。 Specifically, the light diffusion angle of the lens-shaped portion (including one surface of the lens-shaped portion) of the resin leather is preferably greater than 5° and 90° or less, and more preferably 10° or more and 60° or less. If the diffusion angle of the lens-shaped portion of the resin leather exceeds the above range, the influence due to diffusion reflection will increase, and it may be difficult to obtain a high gloss feeling. On the other hand, if the diffusion angle is smaller than the above range, the influence due to specular reflection will become larger, and there may be a case where the glossiness is higher and the glossiness is more easily inspected. The light diffusion angle of the lens shape portion, that is, the diffusion angle when light enters the lens shape portion from the vertical direction (incidence angle 0°).
觀察者在相當於上述擴散角的觀察角度區域內,可檢視到樹脂皮革的高光澤感。 The observer can observe the high gloss feeling of the resin leather in the observation angle region corresponding to the above-mentioned diffusion angle.
本實施形態樹脂皮革的另一態樣係表面有設有複數個具曲面之單位透鏡形狀的透鏡形狀部,且上述單位透鏡形狀的曲率半徑係15μm以上且150μm以下。 In another aspect of the resin leather of this embodiment, a plurality of lens-shaped portions having a unit lens shape with a curved surface are provided on the surface, and the radius of curvature of the unit lens shape is 15 μm or more and 150 μm or less.
本實施形態的樹脂皮革係表面所設置的透鏡形狀部,由具有既定範圍內曲率半徑的單位透鏡形狀複數設置所構成,因而上述S(80-20)及各擴散角均分別可在既定範圍內。藉此,本實施形態的樹脂皮革可調整表面所產生反射光的散射分佈,故能呈現油光經抑制的高光澤感,且配合觀察區域能顯現出由光澤感變化所產生之設計性。 The lens shape portion provided on the surface of the resin leather system of this embodiment is composed of a plurality of unit lens shapes having a radius of curvature within a predetermined range, so the above S (80-20) and each diffusion angle can be within a predetermined range, respectively . In this way, the resin leather of the present embodiment can adjust the scattering distribution of the reflected light generated on the surface, so that it can exhibit a high gloss feeling with suppressed oil shine, and the design property resulting from the change in gloss feeling can be exhibited in conjunction with the observation area.
相關上述另一態樣樹脂皮革的詳細內容,係如前所說明。 The details of the resin leather in another aspect described above are as described above.
本實施形態樹脂皮革之製造方法,係在使用「A.離型片」項所說明的離型片,能於樹脂皮革的樹脂表皮層表面上形成所需單位透鏡形狀及屬於其集合體的透鏡形狀部之方法前提下,其餘並無特別的限定,可採取使用離型片的習知公知合成皮革或人工皮革之製造方法。樹脂皮革的製造方法係可為乾式法、亦可為濕式法 The manufacturing method of the resin leather of this embodiment uses the release sheet described in the section "A. Release sheet" to form the desired unit lens shape and the lens belonging to the aggregate on the surface of the resin skin layer of the resin leather On the premise of the method of the shape part, the rest is not particularly limited, and a conventionally known method of manufacturing synthetic leather or artificial leather using a release sheet can be adopted. The manufacturing method of resin leather can be dry method or wet method
例如當利用乾式法製造樹脂皮革時,在「A.離型片」項所說明離型片的離型層表面上,塗佈樹脂表皮層形成用組成物,經乾燥而形成樹脂表皮層,再於上述樹脂表皮層上經由接著層積層支撐層,經乾燥及熟成後,將離型片予以剝離,便可製得樹脂皮革。上述接著層係可使用樹脂皮革製造時所使用的習知公知組成。 For example, when the resin leather is manufactured by the dry method, the resin skin layer forming composition is coated on the surface of the release layer of the release sheet described in the section "A. Release sheet", and dried to form the resin skin layer, and then After the support layer is laminated on the above resin skin layer, after drying and aging, the release sheet is peeled off to obtain resin leather.

針對使用由實施例1~10及比較例1~2所獲得之離型片而獲得的合成皮革施行以下評價。各評價結果係如表1與表2所示。 The following evaluation was performed about the synthetic leather obtained using the release sheet obtained by Examples 1-10 and Comparative Examples 1-2. The evaluation results are shown in Table 1 and Table 2.
測量將使用實施例1的離型片而獲得之合成皮革的聚胺酯量(含著色劑)設為1時,使用實施例2~10及比較例1~2的離型片所獲得之合成皮革的聚胺酯量(含著色劑)之重量比。 When the amount of polyurethane (containing a colorant) of the synthetic leather obtained using the release sheet of Example 1 was set to 1, the synthetic leather obtained using the release sheets of Examples 2 to 10 and Comparative Examples 1 to 2 was measured. The weight ratio of the amount of polyurethane (including colorant).
針對使用實施例1~10及比較例1~2所獲得之離型片而獲得的合成皮革施行散射光強度測定,從所獲得散射光強度分佈曲線計算出擴散角及S(80-20)值。散射光強度係使用三維變角分光測色系統(GCMS-13型、村上色彩技術研究所股份有限公司製),朝樹脂皮革具備有透鏡形狀部之一面,射入鉛直方向(入射角0°)的光,依受光角度在-60°~60°範圍內、變角間隔1°的條件,測定每個散射角的強度。又,散射光強度分佈曲線係將散射角設為X軸、散射光強度設為Y軸,將散射光強度相對於各散射角進行描點描繪。 The synthetic leather obtained using the release sheets obtained in Examples 1 to 10 and Comparative Examples 1 to 2 was subjected to scattered light intensity measurement, and the diffusion angle and S (80-20) value were calculated from the obtained scattered light intensity distribution curve . The intensity of the scattered light is a three-dimensional variable-angle spectrophotometric color measurement system (GCMS-13 type, manufactured by Murakami Color Technology Research Institute Co., Ltd.), which is directed toward the surface of the resin leather with a lens-shaped part and enters the vertical direction (incident angle 0°) The intensity of each scattering angle is measured according to the condition that the light receiving angle is within the range of -60°~60° and the variable angle interval is 1°. In addition, the scattered light intensity distribution curve system uses a scattering angle as the X axis and a scattered light intensity as the Y axis, and plots the scattered light intensity with respect to each scattering angle.
從使用實施例1~10的離型片所獲得合成皮革切取100mm四方的樣品,將上述樣品放置於桌子上,從上方500mm位置處施行單位透鏡形狀的識別。 A 100 mm square sample was cut from the synthetic leather obtained using the release sheets of Examples 1 to 10, the sample was placed on a table, and unit lens shape recognition was performed from a position of 500 mm above.
再者,從使用比較例1~2的離型片所獲得合成皮革切取100mm四方的樣品,將上述樣品放置於桌子上,從上方500mm位置處施行噴砂粗面的凹凸形狀識別。 In addition, a 100 mm square sample was cut from the synthetic leather obtained using the release sheets of Comparative Examples 1 and 2, the sample was placed on a table, and the rough shape of the sandblasted rough surface was identified from a position of 500 mm above.
試驗環境係設為照度400lux(相當於明亮的辦公室)。從受測者10位(20歲至60歲)計算能檢視到的人數,並施行下述判定。 The test environment is set to 400 lux (equivalent to a bright office). Calculate the number of people that can be inspected from 10 subjects (20 years old to 60 years old) and make the following judgment.
◎◎:0位(完全無法看到) ◎◎: 0 digits (not visible at all)
◎:1~2位(幾乎無法看到) ◎: 1~2 digits (can hardly be seen)
○:3~7位(稍微能看到) ○: 3 to 7 (slightly visible)
△:8位以上(可看到) △: 8 digits or more (visible)
將「(3)單位透鏡形狀檢視性」所使用的各樣品放置於桌子上,在照度400lux(相當於明亮的辦公室)環境下,確認樣品的外觀。在受測者10位(20歲至60歲)中,有感覺光澤感的人數達7位以上的情況便評為樣品的「光澤感高(高光澤感)」。油光感係在受測者10位(20歲至60歲)中,強烈感覺油光感的人數達7位以上的情況便評為樣品「具油光感」。 Place each sample used in "(3) Unit lens shape visibility" on a table, and confirm the appearance of the sample in an environment with an illumination of 400 lux (equivalent to a bright office). Among the 10 subjects (20 years old to 60 years old), when the number of people who felt the glossiness reached 7 or more, the sample was evaluated as "high glossiness (high glossiness)". The oily sensation system is rated as “oily sensation” in the sample of 10 people (20 to 60 years old), and the number of people who strongly feel the oily sensation is 7 or more.
上述外觀評價的結果、實施例1~10的離型片,因為表面設有由具曲面之單位透鏡複數配置所構成的透鏡部,因而使用上述離型片所獲得合成皮革感受到油光經抑制的高光澤感,確認到配合觀察區域的光澤感變化而顯現之設計性。另一方面,比較例1~2的離型 片並未設有具曲面之單位透鏡、及屬於其集合體的透鏡部,使用上述離型片獲得的合成皮革並未感受到高光澤度,而呈偏白色澤,又無法確認到配合觀察區域的光澤感變化而顯現的設計性。 As a result of the above-mentioned appearance evaluation, the release sheets of Examples 1 to 10 are provided with a lens portion composed of a complex arrangement of unit lenses with curved surfaces on the surface, so the synthetic leather obtained using the release sheet feels that the gloss is suppressed The high gloss feel confirms the design that appears in accordance with the change in gloss of the observation area. On the other hand, the release of Comparative Examples 1-2 The sheet is not provided with a unit lens with a curved surface and a lens part belonging to its assembly. The synthetic leather obtained using the release sheet does not feel high gloss, but appears whiteish, and it is impossible to confirm the matching observation area The design of the gloss is changed.
利用比較例1~2的離型片所獲得之合成皮革,因為S(80-20)值並未在所需範圍(4°以上且15°以下)內,因而呈現上述檢視結果。 The synthetic leather obtained by using the release sheets of Comparative Examples 1 and 2 shows the above-mentioned inspection results because the S (80-20) value is not within the required range (4° or more and 15° or less).
再者,由上述外觀評價的結果,使用實施例1~10的離型片所獲得之合成皮革中,使用實施例7與8的離型片所獲得之合成皮革的光澤感較高,但油光感卻較其他實施例強。利用實施例1~6及實施例9~10的離型片所獲得之合成皮革,因為擴散角在所需範圍內(大於5°且在90°以下),因而相較於利用擴散角未在所需範圍內的實施例7~8之離型片所獲得之合成皮革,顯示出能獲得更高的油光抑制效果。 Furthermore, from the results of the above-mentioned appearance evaluation, among the synthetic leathers obtained using the release sheets of Examples 1 to 10, the synthetic leathers obtained using the release sheets of Examples 7 and 8 had a high glossiness, but they were shiny The feeling is stronger than other embodiments. The synthetic leather obtained by using the release sheets of Examples 1 to 6 and Examples 9 to 10 has a diffusion angle within the required range (greater than 5° and below 90°), so it is not The synthetic leathers obtained from the release sheets of Examples 7 to 8 within the required range show that they can obtain a higher gloss effect.
再者,實施例4~6、實施例8及實施例10,因為離型片的單位透鏡設為相對於離型層的透鏡部形成面呈凸形狀,因而相較於實施例1~3、實施例7及實施例9,可降低合成皮革製造時所使用的聚胺酯量。 In addition, in Examples 4 to 6, Example 8, and Example 10, the unit lens of the release sheet is formed to have a convex shape with respect to the lens portion forming surface of the release layer, so compared to Examples 1 to 3, Example 7 and Example 9 can reduce the amount of polyurethane used in the manufacture of synthetic leather.
