Abstract

A thermal transfer sheet comprises a base material that has a concave-convex shape on a surface thereof, a mold release layer that is disposed on the surface of the base material which has the concave-convex shape, and a protective layer that is disposed on the mold release layer. The mold release layer does not include particulate matter, includes a resin in which an amino resin and a hydroxyl group-containing resin are three-dimensionally cross-linked, and has a concave-convex shape reflecting the concave-convex shape of the base material on a surface where the protective layer is disposed. Preferably, a thickness of the mold release layer is between 30% and 120% of an arithmetic average roughness (Ra) of the base material. The protective layer and a colored layer are transferred onto an adherend by heating and adhering a surface where the colored layer of the thermal transfer sheet is disposed to the adherend after the colored layer is formed on the protective layer of the thermal transfer sheet. The concave-convex shape can be provided on the surface of the thermally transferred protective layer, and thus the transferred protective layer has excellent matte properties, and it is possible not to impair the texture of the adherend using gloss of the protective layer.

Description

熱転写用シートおよび印画物の製造方法Sheet for thermal transfer and method for producing printed matter
　本発明は、布などの繊維製品や、紙や木材などに模様や文字などの図柄を転写する際に使用する熱転写用シートに関し、特に、熱転写時に剥離性が良好で、転写された図柄上に保護層を形成することができる熱転写用シートに関する。 The present invention relates to a thermal transfer sheet used when transferring a pattern such as a pattern or a character to a textile product such as cloth or paper or wood, and in particular, it has a good releasability during thermal transfer and is on the transferred pattern. The present invention relates to a thermal transfer sheet capable of forming a protective layer.
　布などの繊維製品や、紙や木材などに模様や文字などの図柄を転写する際には、図柄などを施したい部分に、直接、シルク印刷などにより、着色層を設ける方法や、離型性を有する転写基材上に、図柄などの着色層を形成した後、着色層を転写する方法が用いられている。特に、着色層を保護するための保護層を着色層上に設けやすいため、保護層と着色層とを転写するための転写用シートが用いられている（特許文献１）。 When transferring patterns such as patterns and letters to textile products such as cloth, paper and wood, a method of providing a colored layer directly on the part where the pattern is to be applied, such as silk printing, and releasability A method of transferring a colored layer after a colored layer such as a pattern is formed on a transfer substrate having the above has been used. In particular, since a protective layer for protecting the colored layer is easily provided on the colored layer, a transfer sheet for transferring the protective layer and the colored layer is used (Patent Document 1).
　このような熱転写用シートを用いて転写された図柄は、表面が平滑なものが多く、光沢がある。しかし、被着体として用いられる部材に光沢がないものも多く、転写された図柄にもつや消し感が求められる場合がある。つや消し感を付与するためには、保護層に顔料などを含有せしめ、不透明にすることが考えられるが、保護層を不透明にすることは、着色層の視認性を妨げるため好ましくない。 図 Many of the designs transferred using such a thermal transfer sheet have a smooth surface and are glossy. However, many members used as adherends are not glossy, and there are cases where a transferred pattern has a dull feeling. In order to impart a matte feeling, it is conceivable to make the protective layer contain a pigment or the like to make it opaque, but making the protective layer opaque is not preferable because it hinders the visibility of the colored layer.
　これに対し、つや消し（マット状）表面を持つ印画物を熱転写により形成する手法として、硬化型バインダー樹脂中にフィラーを含む離型層を形成し、その表面を粗面化する技術が知られている（特許文献２）。この技術によれば、離型層の粗面形状が保護層表面に転写され、印画につや消し感を与えることができる。 On the other hand, a technique for forming a release layer containing a filler in a curable binder resin and roughening the surface is known as a technique for forming a printed matter having a matte (matte) surface by thermal transfer. (Patent Document 2). According to this technique, the rough surface shape of the release layer is transferred to the surface of the protective layer, and a matte feeling can be given to the print.

　図柄等を繊維製品などの被転写材に熱転写する場合、所望の図柄だけを転写するために、熱転写用シートを所望の形状にカッティングしたり、着色層と保護層の部分のみをカッティング（ハーフカッティングという）した後、着色層と保護層を加熱転写する方法や、所望の形状の加圧面を持つ加熱・加圧部材を用いて加熱転写することにより、着色層と保護層を加熱加圧部材の形状に転写する方法が採用される。この場合、保護層が転写されるまでは、浮きや剥がれを生じないように保護層と離型層とは良好な接着性で接着し、転写後には両者がきれいに剥がれることが要求される。 When transferring a pattern to a transfer material such as a textile product, in order to transfer only the desired pattern, the thermal transfer sheet is cut into a desired shape, or only the colored layer and the protective layer are cut (half-cutting). After that, the colored layer and the protective layer are heated and transferred using a heating / pressurizing member having a pressurizing surface having a desired shape. A method of transferring to a shape is adopted. In this case, until the protective layer is transferred, it is required that the protective layer and the release layer are bonded with good adhesion so as not to be lifted or peeled off, and that both are neatly peeled off after the transfer.
　しかしマット状印画物を得るために離型層にフィラーを含有せしめた場合には、保護層との関係で適切に選択された離型層の、保護層に対する性質（接着性や剥離性）が変化してしまい、転写前の接着不良による浮きや剥がれを生じたり、熱転写後の剥離不良などを引き起こす可能性がある。 However, when a filler is included in the release layer to obtain a mat-like print, the properties (adhesiveness and releasability) of the release layer appropriately selected in relation to the protective layer with respect to the protective layer It may change and may cause floating or peeling due to poor adhesion before transfer, or may cause poor peeling after thermal transfer.
　そこで、本発明は、熱転写するまで保護層と離型層との接着性が優れ、且つ熱転写後の保護層と離型層との剥離性に優れた熱転写用シートを提供すること、また上記接着性及び剥離性に優れ、つや消し感を付与することができる熱転写用シートを提供することを目的とする。 Therefore, the present invention provides a thermal transfer sheet that has excellent adhesion between the protective layer and the release layer until thermal transfer and has excellent releasability between the protective layer and the release layer after thermal transfer. It aims at providing the sheet | seat for thermal transfer which is excellent in property and peelability, and can provide a matte feeling.

　本発明の熱転写用シートは、基材に、離型層と保護層とをこの順に有する熱転写用シートであって、基材は、表面に凹凸形状を有し、離型層は、アミノ樹脂と、水酸基含有樹脂とを三次元架橋した樹脂を含み、保護層は、セルロース系樹脂を含む。離型層の厚みは、その表面に基材の凹凸形状を反映した凹凸形状が形成される厚みである。
　以下、本発明の熱転写用シートを構成する各要素について詳述する。 The thermal transfer sheet of the present invention is a thermal transfer sheet having a release layer and a protective layer in this order on a substrate, the substrate has an uneven shape on the surface, and the release layer includes an amino resin and In addition, the protective layer contains a cellulosic resin. The thickness of the release layer is a thickness at which an uneven shape reflecting the uneven shape of the substrate is formed on the surface.
Hereafter, each element which comprises the sheet | seat for thermal transfer of this invention is explained in full detail.
　本発明の熱転写用シートに用いられる基材は、表面に凹凸形状を有するものである。このような表面に凹凸形状を有する基材としては、例えば、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタレート等のポリエステル系フィルムや、ポリイミド系フィルム、ポリアラミド系フィルムなどの各種プラスチックフィルムを使用することができる。これらプラスチックフィルムの一方の表面に凹凸形状を形成する方法としては、ブラスト処理、エンボス処理、賦形処理などのほか、凹凸を有する塗膜を形成するなどを適宜選択することができる。特に、凹凸形状を安価に得ることができ、高温でも凹凸形状を維持することができるブラスト処理が好ましい。 The base material used for the thermal transfer sheet of the present invention has an uneven shape on the surface. As such a substrate having a concavo-convex shape on the surface, for example, polyester films such as polyethylene terephthalate, polybutylene terephthalate, and polyethylene naphthalate, and various plastic films such as polyimide films and polyaramid films can be used. it can. As a method for forming a concavo-convex shape on one surface of these plastic films, in addition to a blast treatment, an embossing treatment, a shaping treatment, etc., it is possible to appropriately select formation of a coating film having concavo-convex. In particular, a blast treatment that can obtain an uneven shape at low cost and can maintain the uneven shape even at high temperatures is preferable.
　このような凹凸形状としては、ＪＩＳ　Ｂ０６０１：２００１に準拠した算術平均粗さ（Ｒａ)が、０．３μｍ以上であることが好ましく、さらに好ましくは、０．７μｍ以上である。上限としては、１．３μｍ以下であることが好ましく、さらに好ましくは、１．０μｍ以下である。算術平均粗さ（Ｒａ）を０．３μｍ以上とすることにより、離型層を介して保護層表面に凹凸形状を確実に付与することができる。１．３μｍ以下とすることにより、むらなく離型層を形成することができる。 As such an uneven shape, the arithmetic average roughness (Ra) based on JIS B0601: 2001 is preferably 0.3 μm or more, and more preferably 0.7 μm or more. As an upper limit, it is preferable that it is 1.3 micrometers or less, More preferably, it is 1.0 micrometers or less. By setting the arithmetic average roughness (Ra) to 0.3 μm or more, an uneven shape can be reliably imparted to the surface of the protective layer via the release layer. By setting the thickness to 1.3 μm or less, the release layer can be formed without unevenness.
　プラスチックフィルムの各々の厚みは、２５～２００μｍであることが好ましく、５０～１００μｍであることがより好ましい。２５μｍ以上とすることにより、熱転写用シートとしたときの取り扱い性に優れるものとすることができる。また、２００μｍ以下とすることにより、被貼着物に貼着する際の作業性の低下を防止することができる。 The thickness of each plastic film is preferably 25 to 200 μm, more preferably 50 to 100 μm. By setting the thickness to 25 μm or more, it is possible to obtain excellent handling properties when a thermal transfer sheet is obtained. Moreover, the fall of workability | operativity at the time of sticking to a to-be-adhered thing can be prevented by setting it as 200 micrometers or less.
　離型層は、基材と保護層との間の接着性を調整する役割を担うと共に、基材表面の凹凸形状を保護層に伝える役割を担うものである。そこで、離型層には、離型層を形成した後に、凹凸形状を維持していることが求められる。そのため、離型層は、基材表面の凹凸形状に反映した凹凸形状を持つ厚みとする。図１に、基材の凹凸形状と離型層の厚みとの関係を示す。 The release layer plays a role of adjusting the adhesion between the base material and the protective layer, and also plays a role of transmitting the uneven shape of the base material surface to the protective layer. Therefore, the release layer is required to maintain an uneven shape after the release layer is formed. Therefore, the release layer has a thickness having a concavo-convex shape reflected in the concavo-convex shape on the surface of the substrate. In FIG. 1, the relationship between the uneven | corrugated shape of a base material and the thickness of a release layer is shown.
　凹凸形状を持つ基材１１の表面に、離型層１２を塗工して形成する場合、図１（ｂ）に示すように、離型層１２用塗料の塗工量（坪量）が多すぎる場合には、基材１１の凹凸形状はすべて離型層１２の厚みの中に埋もれてしまい、離型層１２表面には基材１１の凹凸形状を反映した凹凸形状は形成されない。逆に、図１（ｃ）に示すように、離型層１２用塗料の塗工量（坪量）が少なすぎる場合には、離型層１２の厚みのムラが大きくなり、離型層１２で覆われない凸部、すなわち離型層１２が形成されない部分ができてしまう。 When the release layer 12 is formed on the surface of the substrate 11 having an uneven shape, the coating amount (basis weight) of the release layer 12 coating is large as shown in FIG. When too large, all the uneven | corrugated shape of the base material 11 will be buried in the thickness of the release layer 12, and the uneven | corrugated shape reflecting the uneven | corrugated shape of the base material 11 will not be formed in the mold release layer 12 surface. On the contrary, as shown in FIG. 1C, when the coating amount (basis weight) of the paint for the release layer 12 is too small, the unevenness of the thickness of the release layer 12 becomes large, and the release layer 12 As a result, a convex portion that is not covered with, that is, a portion where the release layer 12 is not formed is formed.
　本発明の熱転写シートでは、離型層１２は、図１（ａ）に示すように、基材１１表面全体を覆い且つ基材１１表面の凹凸形状に倣った凹凸形状を持つ。このような離型層１２の厚みは、離型層１２を塗工して形成する場合、均一な厚みではなく、基材の凹部で厚く凸部で薄いものとなる。そこで離型層１２の厚みを次式（１）で定義すると、
［厚み（μｍ）］＝［乾燥塗布量（ｇ／ｍ2）］÷［離型層の密度（ｇ／ｃｍ3）］（１）
離型層の厚みは、基材表面の算術平均粗さ（Ｒａ）の、３０％以上の厚みであることが好ましく、５０％以上の厚みであることがより好ましい。また、上限としては、１２０％以下の厚みであることが好ましく、さらに、８０％以下の厚みであることがより好ましい。基材表面の算術平均粗さ（Ｒａ）の３０％以上とすることにより、むらなく離型層を形成することができ、基材表面の算術平均粗さ（Ｒａ）の１２０％以下とすることにより、離型層で凹凸形状を維持し、保護層表面に凹凸形状を確実に付与することができる。具体的な厚みとしては、０．２～１．５μｍであることが好ましい。 In the thermal transfer sheet of the present invention, the release layer 12 has an uneven shape that covers the entire surface of the substrate 11 and follows the uneven shape of the surface of the substrate 11 as shown in FIG. When the release layer 12 is formed by coating, the thickness of the release layer 12 is not a uniform thickness, but is thick at the concave portion of the substrate and thin at the convex portion. Therefore, when the thickness of the release layer 12 is defined by the following formula (1),
[Thickness (μm)] = [Dry coating amount (g / m 2 )] ÷ [Density of release layer (g / cm 3 )] (1)
The thickness of the release layer is preferably 30% or more, more preferably 50% or more of the arithmetic average roughness (Ra) of the substrate surface. Moreover, as an upper limit, it is preferable that it is 120% or less of thickness, and it is more preferable that it is 80% or less of thickness. By setting it to 30% or more of the arithmetic average roughness (Ra) of the substrate surface, a release layer can be formed uniformly, and to be 120% or less of the arithmetic average roughness (Ra) of the substrate surface. Thus, the uneven shape can be maintained in the release layer, and the uneven shape can be reliably imparted to the surface of the protective layer. The specific thickness is preferably 0.2 to 1.5 μm.

In particular, the use of a hydroxyl group-containing resin copolymerized with a long-chain alkyl improves the releasability. Therefore, it is preferable.
　アミノ樹脂と水酸基含有樹脂とを三次元架橋させた樹脂を用いることによって、後述する保護層との熱転写前までの接着性を維持することができ、本発明の熱転写シートを使用する前に保護層が離型層から剥がれたり浮いたりするのを防止することができる。また熱転写後の剥離性を良好なものとすることができる。 By using a resin obtained by three-dimensionally cross-linking an amino resin and a hydroxyl group-containing resin, it is possible to maintain the adhesiveness before thermal transfer with a protective layer described later, and before using the thermal transfer sheet of the present invention, the protective layer Can be prevented from peeling off or floating from the release layer.

And By setting it as such a range, it is easy to adjust the adhesiveness before thermal transfer with the protective layer and the peelability after thermal transfer.
　なお、離型層には、基材や保護層との接着性や保護層との剥離性などの離型層として必要な性質を阻害しない範囲で、アミノ樹脂と水酸基含有樹脂とを三次元架橋させた樹脂以外の他の樹脂を含有することができる。他の樹脂としては、例えばエポキシ樹脂等の熱硬化性樹脂やポリエステル系樹脂やアクリル系樹脂等の熱可塑性樹脂を用いることができる。他の樹脂として熱硬化性樹脂を用いる場合には、全樹脂成分の８０％以下であることが好ましく、５０％以下がより好ましい。他の樹脂として熱硬化性樹脂以外の樹脂を用いる場合には、全樹脂成分の２０％以下であることが好ましく、１０％以下がより好ましい。 For the release layer, amino resin and hydroxyl group-containing resin are three-dimensionally cross-linked within a range that does not impair the properties required for the release layer, such as adhesion to the base material and protective layer, and peelability from the protective layer. Resins other than the resin made can be contained. Examples of other resins that can be used include thermosetting resins such as epoxy resins, and thermoplastic resins such as polyester resins and acrylic resins. When a thermosetting resin is used as the other resin, it is preferably 80% or less, more preferably 50% or less of the total resin component. When a resin other than a thermosetting resin is used as the other resin, it is preferably 20% or less of the total resin component, and more preferably 10% or less.

As the cellulose resin, for example, cellulose esters such as cellulose acetate butyrate, cellulose acetate propionate, nitrocellulose, and cellulose acetate can be used. By using such a cellulose-based resin as a protective layer, even when transferred to a textile product such as a cloth, it is possible to follow the elongation of the fiber and prevent the protective layer from cracking. it can.

Moreover, by setting it as 2 micrometers or less, while being able to maintain the texture of a to-be-adhered body, cutting property can be acquired. Here, the cutting property means that when only a part of the protective layer is thermally transferred to the adherend together with the colored layer, the part of the protective layer that has been thermally transferred can be cleanly cut with the other part (the part that is not thermally transferred). To tell.
　各層には、上述した樹脂のほかに、レベリング剤、酸化防止剤、紫外線吸収剤などの添加剤を添加してもよい。 In addition to the resin described above, additives such as a leveling agent, an antioxidant, and an ultraviolet absorber may be added to each layer.

　次に、本発明の印画物の製造方法を説明する。本発明の印画物の製造方法は、上述した本発明の熱転写用シートを用いるものであり、熱転写用シートの着色層が設けられた面を被着体へ加熱貼着することにより、保護層と着色層とを被着体上へ転写するものである。 Next, a method for producing a printed material according to the present invention will be described. The method for producing a printed product of the present invention uses the thermal transfer sheet of the present invention described above, and heat-sticks the surface provided with the colored layer of the thermal transfer sheet to the adherend, thereby providing a protective layer and The colored layer is transferred onto the adherend.
　所望の形状（文字、図形など）の着色層と保護層を転写する方法には、図２～図４に示すようにいくつかの方法がある。保護層１３上に着色層１４を形成した後、熱転写用シート１０を所望の形にカッティングし、熱転写用シート１０の着色層が設けられた面を被着体２０へ加熱貼着する方法（図２：方法１）、保護層１３上に着色層１４を形成した後、基材１１及び離型層１２を切り離すことなく保護層１３と着色層１４だけを所望の形にカッティング（ハーフカット）し、所望の形以外の部分の保護層（と着色層）を離型層１２から剥がして除去し、残った着色層とその上にある保護層の部分を被着体２０上へ転写する方法（図３：方法２）、保護層１３上に着色層１４を形成した後、熱転写用シート１０の着色層１４が設けられた面を被着体２０に接触させて、所望の形状の加圧面を持つ加熱・加圧手段３０を熱転写用シートの基材側から加熱・加圧することにより、加圧面の形状と同形状の着色層１４とその上にある保護層１３の部分とを被着体２０上へ転写する方法（図４：方法３）などである。 There are several methods for transferring a colored layer and a protective layer having a desired shape (characters, figures, etc.) as shown in FIGS. After forming the colored layer 14 on the protective layer 13, the thermal transfer sheet 10 is cut into a desired shape, and the surface of the thermal transfer sheet 10 on which the colored layer is provided is heated and adhered to the adherend 20 (FIG. 2: Method 1) After forming the colored layer 14 on the protective layer 13, only the protective layer 13 and the colored layer 14 are cut (half cut) into a desired shape without separating the base material 11 and the release layer 12. A method of removing the protective layer (and the colored layer) in a portion other than the desired shape by peeling off the release layer 12 and transferring the remaining colored layer and the portion of the protective layer on the layer onto the adherend 20 ( FIG. 3: Method 2) After forming the colored layer 14 on the protective layer 13, the surface of the thermal transfer sheet 10 on which the colored layer 14 is provided is brought into contact with the adherend 20 to form a pressure surface having a desired shape. The heating / pressurizing means 30 is heated and pressed from the substrate side of the thermal transfer sheet. And a method of transferring a colored layer 14 of the same shape of the pressing surface and the portion of the protective layer 13 located thereon to the adherend 20 above (Figure 4: Method 3), and the like.
　いずれの場合にも、加熱貼着時の温度は、１４０～２００℃程度が好ましく、適宜圧力を加えることが好ましい。被着体としては、布などの繊維製品や、紙や木材などを用いることができる。 In any case, the temperature at the time of heating and sticking is preferably about 140 to 200 ° C., and it is preferable to apply pressure appropriately. As the adherend, fiber products such as cloth, paper, wood and the like can be used.
　本発明の熱転写用シートは、離型層の表面を粒子状物質によって凹凸にするのではないので、保護層と離型層との熱転写前（常温）における適切な接着性を維持することができ、方法１や方法２でカッティングする際に、保護層が離型層から剥がれたり浮いたりすることがなく作業性がよい。また、保護層のカッティング性（熱転写される部分を他の部分からきれいに切り離すことができる性質）が良好であり、方法３の熱転写方法を採用した時に、きれいな印画が得られる。 In the thermal transfer sheet of the present invention, the surface of the release layer is not made uneven by the particulate matter, so that it is possible to maintain appropriate adhesion between the protective layer and the release layer before the thermal transfer (at room temperature). When the cutting is performed by the method 1 or the method 2, the workability is good because the protective layer is not peeled off or floated from the release layer. In addition, the protective layer has good cutting properties (property that allows a portion to be thermally transferred to be separated cleanly from other portions), and when the thermal transfer method of Method 3 is adopted, a beautiful print can be obtained.
　また本発明の熱転写用シートは、表面に凹凸形状を有する基材を用い、離型層の厚みを適切な厚みとすることによって、熱転写された保護層表面に、凹凸形状を付与することができるため、転写された保護層は、つや消し性に優れており、保護層の光沢により被着体のもつ風合いを損なわないものとすることができる。 In addition, the thermal transfer sheet of the present invention can impart a concavo-convex shape to the surface of the heat-transferred protective layer by using a substrate having a concavo-convex shape on the surface and setting the release layer to an appropriate thickness. For this reason, the transferred protective layer has excellent matte properties, and the gloss of the protective layer does not impair the texture of the adherend.

The results are shown in Table 1.
（２）剥離性
　実施例１～５、比較例１～３の熱転写用シートの保護層上に、ウレタン系着色層を厚み３０μｍとして設け、ハーフカッティングした後、着色層面をナイロン製布地と向かい合わせ、１８０℃、５０ｋＰａ、１０秒で加熱貼着し、熱転写シートの離型層と基材を剥離し、着色層と保護層とが布地に転写された印画物を作製した。離型層と保護層との間の剥離強度を測定した。剥離強度の測定は、熱転写シート側を１８０°方向、３００ｍｍ／ｍｉｎの速度で剥離した時の剥離に必要な力（単位幅あたりの平均荷重）を測定することにより行った。その結果、剥離強度が０．１（Ｎ／２５ｍｍ幅）以下（極めて容易に剥離）あるいは１．５（Ｎ／２５ｍｍ幅）以上（剥離しない）の場合を「×」、０．１～０．５（Ｎ／２５ｍｍ幅）（容易に剥離）の場合を「○」、０．５～１．５（Ｎ／２５ｍｍ幅）（剥離感は重いが剥離したもの）を「△」とした。結果を表１に示す。 (2) Peelability A urethane-based colored layer having a thickness of 30 μm is provided on the protective layer of the thermal transfer sheet of Examples 1 to 5 and Comparative Examples 1 to 3, and after half-cutting, the colored layer surface faces the nylon fabric. At 180 ° C., 50 kPa, heated for 10 seconds, the release layer and the base material of the thermal transfer sheet were peeled off, and a printed material in which the colored layer and the protective layer were transferred to the fabric was produced. The peel strength between the release layer and the protective layer was measured. The peel strength was measured by measuring the force (average load per unit width) required for peeling when the thermal transfer sheet side was peeled off at a speed of 300 mm / min in the 180 ° direction. As a result, when the peel strength is 0.1 (N / 25 mm width) or less (peeling very easily) or 1.5 (N / 25 mm width) or more (not peeled), “x”, 0.1-0. In the case of 5 (N / 25 mm width) (easy peeling), “◯” was assigned, and 0.5 to 1.5 (N / 25 mm width) (heavy peeling feeling but peeled) was assigned as “Δ”. The results are shown in Table 1.

　実施例１～５の熱転写用シートは、離型層が、アミノ樹脂と水酸基含有樹脂とを三次元架橋した樹脂を含み、離型層の厚みが、基材の算術平均粗さ（Ｒａ）の３０～１２０％の範囲内であり、保護層が、セルロース系樹脂を含むものであるため、転写前の保護層と離型層との接着性が良好であり、転写後の保護層と離型層との剥離性が良好であった。また、離型層に凹凸形状を維持することができるものであるため、保護層表面がつや消し性を有するものであった。 In the thermal transfer sheets of Examples 1 to 5, the release layer includes a resin in which an amino resin and a hydroxyl group-containing resin are three-dimensionally cross-linked, and the thickness of the release layer is the arithmetic average roughness (Ra) of the substrate. Since it is within the range of 30 to 120% and the protective layer contains a cellulose-based resin, the adhesion between the protective layer before transfer and the release layer is good, and the protective layer and release layer after transfer The peelability of was good. Moreover, since the uneven | corrugated shape can be maintained in a mold release layer, the protective layer surface had frosting property.
　比較例１の熱転写用シートは、離型層の厚みが、基材の算術平均粗さ（Ｒａ）の２５％未満であって、離型層が基材の凹凸形状全体を覆うように形成されなかったため、転写前の保護層と離型層との接着性が劣るものとなった。 The thermal transfer sheet of Comparative Example 1 is formed so that the thickness of the release layer is less than 25% of the arithmetic average roughness (Ra) of the substrate, and the release layer covers the entire uneven shape of the substrate. As a result, the adhesion between the protective layer and the release layer before transfer was inferior.
　比較例２の熱転写用シートは、離型層の厚みが、基材の算術平均粗さ（Ｒａ）の１３０％以上であって、離型層に凹凸形状を維持することができなかったため、転写後に保護層と離型層との接着力が若干強まり、剥離性が劣るものとなった。また、離型層に凹凸形状を維持することができなかったため、保護層表面に凹凸形状を転写することができず、印画物につや消し性を付与することができなかった。 In the thermal transfer sheet of Comparative Example 2, the thickness of the release layer was 130% or more of the arithmetic average roughness (Ra) of the base material, and the uneven shape could not be maintained in the release layer. Later, the adhesive force between the protective layer and the release layer was slightly increased, and the peelability was poor. Further, since the uneven shape could not be maintained on the release layer, the uneven shape could not be transferred to the surface of the protective layer, and the matte property could not be imparted to the printed material.
　比較例３の熱転写用シートは、離型層がシリコーン樹脂であるため、熱転写前の保護層との接着性が悪く、カッティング時に浮や剥がれを生じた。また、熱転写後の保護層との接着性も悪いものとなった。 Since the release layer of the thermal transfer sheet of Comparative Example 3 is a silicone resin, the adhesiveness to the protective layer before thermal transfer was poor, and floating and peeling occurred during cutting. Moreover, the adhesiveness with the protective layer after thermal transfer was also poor.
