Problems solved by technology

[0010] However, in this method, there are many cumbersome treatment steps called embossing formation, electroless plating catalyst application, heat treatment, electroless plating treatment water including exposure and development steps.
Therefore, it is not possible to manufacture a light-shielding layer for a display device at low cost.

Embodiment 1～5

[0153]

[0154] In 1000ml of pure water, dissolve 23.1g of silver (I) acetate, 65.1g of tin (II) acetate, 54g of gluconic acid, 45g of sodium pyrophosphate, 2g of polyethylene glycol (molecular weight 3,000) and E735 (ISP・Japan Co., Ltd. ) system; vinylpyrrolidone / vinyl acetate copolymer) 5g to obtain solution 1.

[0155] Separately, 36.1 g of hydroxyacetone was dissolved in 500 ml of pure water to obtain a solution 2.

[0156] The obtained solution 1 was vigorously stirred while being kept at 25° C., and at the same time, the solution 2 was added thereto over 2 minutes, and stirring was continued slowly for 6 hours. In this way, the mixed solution turned black, and metal particles having silver-tin alloy parts (particles containing silver-tin alloy parts) were obtained. Next, the solution was centrifuged to precipitate the silver-tin alloy-containing particles. Centrifugation was divided into small portions of 150 ml, and was performed for 30 minutes at a rotation speed o...

Embodiment 6～10

[0248] The average particle sizes of the silver-tin alloy part-containing particles in the silver-tin alloy part-containing particle dispersion liquid A1 used in Example 3 are 20 nm, 60 nm, 100 nm, 250 nm, and 500 nm, respectively, in the same manner as in Example 3 Then, a light-shielding layer for a display device was formed. The results are shown in Table 2.

[0249] The optical density, film thickness, black tone, heating change of tone, and air bubbles all meet the practical level.

Embodiment 11～20

[0254] In Examples 1-10, except not having provided the protective layer on the photosensitive layer, it carried out similarly to Examples 1-10, respectively, and produced the light-shielding layer for display devices. These samples cannot be used in the 70mJ / cm2 ultra-high pressure mercury lamp 2 The light-shielding layer for display devices can be formed under the exposure of 500mJ / cm 2 A good light-shielding layer for a display device was obtained under a certain exposure. Therefore, when making samples used in film thickness measurement, optical density measurement, and volume fraction measurement, the exposure conditions were changed from 70mJ / cm 2 Changed to 500mJ / cm 2 . The results are shown in Table 3.

Abstract

This invention provides a colored composition that contains metal particles having a silver tin alloy part, has an optical density, after film formation, of not less than 3.5 per [mu]m of the dried film thickness, preferably has a volume fraction of the metal particles having a silver tin alloy part in the solid matter of 0.05 to 0.7 and can satisfy the requirement that, in a light shielding layer formed by coating the colored composition, XYZ colorimetric chromaticity coordinates (x, y) of C light source transmitted light and the chromaticity coordinates (x0, y0) of the above light source have a relationship represented by (x-x0)<2> + (y-y0)<2> <= 0.01.

Description

technical field [0001] The present invention relates to a coloring composition, a photosensitive transfer material, a light-shielding layer for a display device using them, a method for producing the same, a color filter, a liquid crystal display element, and a substrate with a light-shielding layer for a display device. Background technique [0002] For color filters used in color liquid crystal displays, etc., colored pixel layers (R, G, B) are formed on a transparent substrate, and then, in order to improve display contrast, etc. A light-shielding layer for a display device is formed between the colored pixels. In particular, in an active-matrix-driven liquid crystal display element using a thin-film transistor (TFT), in order to prevent the reduction of image quality caused by the light-induced current leakage of the thin-film transistor, it is also required that the light-shielding layer for the display device has a high of shading. [0003] As a method of forming a l...
