Description
本發明係將具有面狀表面的對象物之前述表面的全部或一部分(以下稱為表面部)之顏色,使用光致變色化合物,以及對前述光致變色化合物使用產生光致變色的波長之光來可逆地使其變色之方法。In the present invention, a photochromic compound is used for the color of all or a part of the surface (hereinafter referred to as a surface portion) of an object having a planar surface, and light of a wavelength that produces photochromic is used for the photochromic compound. A method of reversibly discoloring it.
從前,在指甲(包括指甲貼片,以下亦同)或手提包等具有面狀的表面的對象物之該表面,利用光致變色來著色的技術可由專利文獻1、2等得知。In the past, techniques for coloring the surface of an object having a planar surface such as nails (including nail patches, the same applies hereinafter) and handbags by photochromism are known from
關於有機電致變色(electrochromic)化合物,CMY(青、洋紅、黃)等鮮明的發色反應之電氣控制已經成功,但停止供電的話,短時間內就會回到原來的顏色。此外,有機、無機之混成(混合)電致變色化合物的開發也在進行著,但這也是停止供電的話,變色狀態就只能維持一段時間而已,無法持續地回復原來顏色這一點,與習知的電致變色材料是相同的。因此,並不適合於改變製品(對象物)的顏色而長時間保持在此狀態之利用方式。此外,根據習知的電致變色化合物之面狀部的顏色變化,為了電氣控制發色反應,諸如電源之類的電氣系統是不可欠缺的,這點仍有欠缺泛用性的遺憾。Regarding organic electrochromic compounds, the electrical control of vivid color-developing reactions such as CMY (cyan, magenta, yellow) has been successful, but if the power supply is stopped, the original color will return to the original color in a short time. In addition, the development of organic and inorganic hybrid (mixed) electrochromic compounds is also underway, but if the power supply is stopped, the discoloration state can only be maintained for a period of time, and the original color cannot be restored continuously. The electrochromic materials are the same. Therefore, it is not suitable for a utilization method in which the color of a product (object) is changed and kept in this state for a long time. In addition, according to the color change of the planar portion of the conventional electrochromic compound, an electrical system such as a power source is indispensable in order to electrically control the color-developing reaction, which unfortunately lacks universality.
然而,照到光時單一化合物不改變分子量而可逆地產生顏色不同的二個異性體(A、B)的現象,為已知的光致變色機制。發生光致變色機制的光致變色材,是照射特定波長的光時顏色會可逆地改變之化合物。其中,應用了銀化合物之「固體多色光致變色」,是對固體照射特定波長的光時固體變色為對應於該照射的光的波長之色,照射紫外區域以外的光會回到原來顏色的可逆性現象。 順帶一提,有種化學構造極為類似而且分子狀態不同的三種化合物分別照射特定波長的光時會由無色變成藍色(1a)、紅色(2a)、黃色(3a)之化合物混合而成的單晶(混晶)之光致變色化合物。此光致變色化合物,照射特定波長的光時,發出藍/紅/黃色,進而由偏光吸收光譜解析,確認了三成分的光致變色反應(光致變色機制)是保持在結晶狀態下進行的。此光致變色化合物,為單晶之二芳乙烯,即使為單晶也可以呈現可逆地變化為各種顏色之多色光致變色機制。又,二芳乙烯的光致變色反應,於紫外區域的狹窄頻帶的波長受到影響而變色,變色之色具有容易以可見光區域的波長之光照而回到原來顏色的特性。 However, a phenomenon in which a single compound reversibly produces two isoforms (A, B) with different colors without changing the molecular weight when exposed to light is a known photochromic mechanism. A photochromic material with a photochromic mechanism is a compound whose color changes reversibly when irradiated with light of a specific wavelength. Among them, "solid polychromatic photochromism" using a silver compound is a process in which the solid changes color to the color corresponding to the wavelength of the irradiated light when the solid is irradiated with light of a specific wavelength, and the light outside the ultraviolet region returns to the original color. reversible phenomenon. By the way, there is a single compound in which three compounds with very similar chemical structures and different molecular states are mixed from colorless to blue (1a), red (2a), and yellow (3a) when irradiated with light of a specific wavelength. Crystalline (mixed crystal) photochromic compounds. This photochromic compound emits blue/red/yellow when irradiated with light of a specific wavelength, and further analysis of the polarized light absorption spectrum confirms that the three-component photochromic reaction (photochromic mechanism) is maintained in a crystalline state. . This photochromic compound is a single crystal of diarylene, and even a single crystal can exhibit a polychromatic photochromic mechanism of reversibly changing into various colors. In addition, the photochromic reaction of vinylidene is affected by the wavelength of a narrow band in the ultraviolet region and changes color, and the discolored color has the characteristic that it is easy to return to the original color by the light of the wavelength of the visible light region.
另一方面,在銀鹽彩色相片等相片用感光材料(銀鹽相片感光材料等)的領域,以提高該材料的光牢固性為課題,所以把自然光等光照射所導致的濃度降低(光致變色機制=光致變色反應)當作是負面的現象,為了抑制此一現象而進行種種的研究開發。例如,富士軟片(Fuji Film)公司製造的可遮斷特定波長的波長截止劑,係以防止銀鹽照片的褪色/色再現性為目的可以選擇性截止(遮斷)特定的不要波長之特定波長的波長截止劑以「COMFOGUARD」之商品名在市面上銷售。此波長截止劑,能夠以20nm為單位調整所欲截止的光的波長,可以在紫外區域到紅外區域之間因應需要自由地選擇要截止的波長區域。On the other hand, in the field of photosensitive materials for photographs such as silver halide color photographs (silver halide photographic photographic materials, etc.), it is an issue to improve the light fastness of the material, so the density caused by exposure to light such as natural light is reduced (photosensitive materials, etc.). Discoloration mechanism = photochromic reaction) is regarded as a negative phenomenon, and various research and development are carried out in order to suppress this phenomenon. For example, a wavelength cutoff agent that can block specific wavelengths manufactured by Fuji Film Co., Ltd. can selectively block (block) specific wavelengths of specific unwanted wavelengths for the purpose of preventing fading/color reproducibility of silver salt photographs. The wavelength cut-off agent is sold in the market under the trade name of "COMFOGUARD". This wavelength cut-off agent can adjust the wavelength of light to be cut off in units of 20 nm, and can freely select the wavelength range to be cut off between the ultraviolet region and the infrared region according to needs.
本案發明人,著眼於前述包含二芳乙烯的光致變色化合物接受到特定帶域的光時就可逆地變色之光致變色材的特性,以及在紫外區域到紅外區域之間可以截止掉任意的波長之波長截止劑的機能,而得到使變色為目的色的前述光致變色材的顏色,在使用截止所要的帶域的波長之波長截止劑時,於自然光之下可以維持所要的時間之想法。 例如,對以特定的光致變色化合物覆蓋表面之對象物,照射可發生光致變色機制的特定波長的紫外區域的光時,可以使前述對象物的表面顏色變色為目的色。為了維持變色後之色,以遮斷包含於自然光的紫外區域的波長之波長截止劑覆蓋前述對象物表面的話,可以在所要的時間內維持變化後之色而抑制顏色的褪色。 The inventors of the present application have paid attention to the characteristics of the photochromic material that the aforementioned photochromic compound containing diarylidene reversibly changes color when it receives light in a specific band, and that it can cut off any arbitrary color between the ultraviolet region and the infrared region. The function of the wavelength cut-off agent to obtain the color of the photochromic material that makes the color change the target color, and the idea that when a wavelength cut-off agent that cuts the wavelength of the desired band is used, it can be maintained under natural light for a desired time. . For example, when an object whose surface is covered with a specific photochromic compound is irradiated with light in the ultraviolet region of a specific wavelength that can generate a photochromic mechanism, the color of the surface of the object can be changed to a desired color. In order to maintain the color after discoloration, if the surface of the object is covered with a wavelength-cutting agent that blocks wavelengths included in the ultraviolet region of natural light, the changed color can be maintained for a desired time and fading of the color can be suppressed.
本案發明人等,進而著眼於二芳乙烯,雖容易受到紫外區域的波長的影響,另一方面有不容易受到可見光區域的波長的影響的特性,而使對象物的表面(製品的表面部)以二芳乙烯覆蓋,於該二芳乙烯的表面照射紫外區域的光而使前述二芳乙烯變色為目的顏色,其後,使前述表面部以截止自然光所包含的紫外區域的波長之波長截止劑來塗覆,可以截止自然光所含的紫外區域的波長而使前述變色後之色彩維持一定時間之見解。 [先前技術文獻] [專利文獻] The inventors of the present application have further focused on vinylidene, although it is easily affected by the wavelength of the ultraviolet region, on the other hand, it is not easily affected by the wavelength of the visible light region, and the surface of the object (surface part of the product) Covering with vinylene, irradiating the surface of the vinylaryne with light in the ultraviolet region to discolor the vinylidene to the desired color, and then applying a wavelength cutoff agent that cuts the wavelength of the ultraviolet region included in the natural light on the surface. By coating, it is possible to cut off the wavelength of the ultraviolet region contained in natural light and maintain the color after the aforementioned discoloration for a certain period of time.

在本發明利用之紫外區域的光,依波長分類,可分成波長380-200nm的近紫外線(near UV)、波長200-10nm的遠紫外線或真空紫外線(farUV(FUV)或vacuumUV(VUV))、波長121-10nm的極紫外線或極端紫外線(extremeUV,EUVorXUV)。此外,由人類健康或對環境的影響之觀點而言,近紫外線可進一步分為UVA(400-315nm)、UVB(315~280nm)、UVC(未滿280nm)。又,光蝕刻或雷射技術上,遠紫外線(deepUV(DUV))與前述FUV不同,指波長300nm以下的紫外線。太陽光中,包含波長為前述UVA、UVB、UVC的紫外線,其中UVA、UVB會通過臭氧層而到達地表。但是,UVC被物質大量吸收,通常無法通過大氣。到達地表的紫外線的99%為UVA(又,有些UVC是由臭氧層的反應而被生成的)。The light in the ultraviolet region used in the present invention can be classified according to wavelength, and can be divided into near ultraviolet (near UV) with wavelength of 380-200 nm, far ultraviolet or vacuum ultraviolet (farUV (FUV) or vacuumUV (VUV)) with wavelength of 200-10 nm, Extreme ultraviolet or extreme ultraviolet (extremeUV, EUVorXUV) with a wavelength of 121-10nm. In addition, from the viewpoint of human health or environmental impact, near-ultraviolet rays can be further classified into UVA (400-315 nm), UVB (315-280 nm), and UVC (less than 280 nm). In addition, in photolithography or laser technology, deep UV (DUV) refers to ultraviolet rays with a wavelength of 300 nm or less, which is different from the aforementioned FUV. Sunlight includes ultraviolet rays with wavelengths of the aforementioned UVA, UVB, and UVC, among which UVA and UVB pass through the ozone layer to reach the surface. However, UVC is heavily absorbed by substances and generally cannot pass through the atmosphere. 99% of the ultraviolet rays reaching the surface are UVA (also, some UVC is generated by the reaction of the ozone layer).
於本發明,被塗布於製品表面之二芳乙烯,在藉由光照射手段而接收紫外區域的波長時會同時發出藍綠、洋紅、黃之三原色因而製品表面呈黑色。於是,藉由光照射手段來控制供使發出的三原色的每一種顏色分別褪色之用的可見光區域的特定波長的光之照射輸出與時間而作成目的之發出色調。 另一方面,本發明係將可以截止自然光中包含許多的UVA(400~315nm)之波長截止劑塗布於前述二芳乙烯。因此,藉由光照射手段照射於二芳乙烯的紫外區域的波長,係自然光中幾乎不包含UVB(315~280nm)或UVC(未滿280nm)等的特定波長。在此,增加光照射手段的輸出可以補充最大濃度的發色。 本發明係對於二芳乙烯的發色使用可以遮斷自然光中包含許多的UVA之波長截止劑,因此發色不受自然光中所含紫外線之影響而僅受可見光引起的褪色變化之影響。由可見光引起的褪色需要數分鐘到數小時的褪色。 本發明,活用根據二芳乙烯之紫外區域波長的照射導致的瞬間三原色所產生之黑色發色與特定波長的可見區域之光照射於黑色發色之調色、藉由截止UVA之波長截止劑的使用而僅使不受到紫外線影響的可見光線導致和緩的褪色的特性,而使發色的任意色彩在自然光或照明光之下可以維持一定時間。 In the present invention, the vinylidene coated on the surface of the product will simultaneously emit three primary colors of blue-green, magenta and yellow when it receives wavelengths in the ultraviolet region by means of light irradiation, so the surface of the product is black. Then, by controlling the light irradiation output and time of a specific wavelength of light in the visible light region for fading each of the emitted three primary colors, the intended emission color tone is made. On the other hand, in the present invention, a wavelength cut-off agent capable of cutting off a large amount of UVA (400-315 nm) contained in natural light is applied to the aforementioned diarylidene. Therefore, the wavelength of the ultraviolet region irradiated to the vinylidene by the light irradiation means hardly includes specific wavelengths such as UVB (315 to 280 nm) and UVC (less than 280 nm) in natural light. Here, increasing the output of the light irradiation means can supplement the color development of the maximum density. The present invention uses a wavelength cut-off agent that can block a lot of UVA contained in natural light for the color development of vinylidene, so the color development is not affected by ultraviolet rays contained in natural light, but only affected by fading changes caused by visible light. Fading caused by visible light takes minutes to hours. In the present invention, the black color generated by the instantaneous three primary colors caused by the irradiation of the ultraviolet region wavelength of vinylidene and the light in the visible region of a specific wavelength are utilized to irradiate the black color tones, and the UVA-cutting wavelength cut-off agent Use only visible light that is not affected by ultraviolet light to cause gentle fading, and any color of the color can be maintained for a certain period of time under natural light or illumination light.
