Problems solved by technology

On the other hand, there is a problem in that a vacuum film-forming process such as vapor deposition and sputtering and an etching process are required, and the cost increases.
However, on the other hand, there are problems such as poor temporal stability of the coating liquid containing the metal fine particles and aggregation.
Also, there is the issue of sensitivity deteriorating over time

Embodiment 1

[0200] (Example 1): coating method

[0201]

[0202] In 1000ml of pure water, dissolve 23.1g of silver acetate (I), 65.1g of tin (II) acetate, 54g of gluconic acid, 45g of sodium pyrophosphate, 2g of polyethylene glycol (molecular weight 3,000) and PVP-K30 Japan Co., Ltd.; polyvinylpyrrolidone polymer) 5 g, and a solution 1 was obtained.

[0203] Separately, 46.1 g of hydroxyacetone was dissolved in 500 ml of pure water to obtain a solution 2.

[0204]On the one hand, the above-obtained solution 1 was kept at 25° C., on the other hand, the above-mentioned solution 2 was added thereto over 2 to 2 minutes while vigorously stirring, and the stirring was continued slowly for 6 hours. Then, the mixed solution turns black, and metal particles having silver-tin alloy parts (hereinafter, sometimes referred to as "silver-tin alloy part-containing particles") are obtained. Then, the mixed solution was centrifuged to precipitate the silver-containing tin alloy particles. The operati...

Embodiment 2～6 and comparative example 1、2

[0297] (Examples 2-6 and Comparative Examples 1 and 2): Coating method

[0298] In the above-mentioned Example 1, except that the photosensitive coating liquid A1 for BM was changed to A2-A8 described in Table 1, a black matrix, a color filter, and a liquid crystal were prepared in the same manner as in Example 1. display device.

Embodiment 7

[0299] (Example 7) transfer method

[0300] In the said Example 1, except having changed the manufacturing method of the black matrix into the following transfer method, the color filter and the liquid crystal display device were manufactured by the same method.

[0301]

[0302] -Production of photosensitive transfer material-

[0303] On a polyethylene terephthalate film temporary support (PET temporary support) with a thickness of 75 μm, apply a coating liquid for a thermoplastic resin layer consisting of the following formulation H1 using a slit nozzle and let it dry , forming a thermoplastic resin layer. Then, an intermediate layer coating liquid composed of the following formulation P1 was further applied on the thermoplastic resin layer, dried, and the intermediate layer was laminated. Next, the photosensitive coating liquid A1 for BM prepared in Example 1 was apply|coated and dried on the intermediate layer, and the black photosensitive composition layer was furthe...

Abstract

The present invention provides a photosensitive compound and a photosensitive transfer-printing material using the photosensitive compound, and the lightproof film which is used for the display device and the making method, black matrix, cardinal plate with lightproof film and the display device, the photosensitive compound will not come out the agglomeration of the metal particle, and the sensitivity is good when it is used as photosensitive material in a long time. The photosensitive transfer-printing material of the invention is characterized in that it at least includes: (A) metal particles or particle comprising metal, (B) at least one photopolymerization initiator choosing from the free aminoacetophenone, acyl phosphine oxide and the group composed of oxime-ester, (C) resin and at least one kind of its precursors.

Description

technical field [0001] The present invention relates to a photosensitive composition suitable for producing a color filter constituting a display device, a photosensitive transfer material using the photosensitive composition, a light-shielding film for a display device, a method for producing the same, and a black matrix (black matrix). matrix), a substrate with a light-shielding film, and a display device. Background technique [0002] In recent years, in order to improve the contrast of displayed images, the optical density of the black matrix is ​​required to be as high as 4.0 or more. On the other hand, when the thickness of the black matrix is ​​thick, it affects the surface smoothness of the color filter. Therefore, it is necessary to thin the black matrix. [0003] Usually, a metal thin film is used to manufacture a black matrix for a display device with high light-shielding properties. It utilizes a method in which a photoresist is applied to a thin metal film su...
