[0146] The present invention will be described below based on examples.

Synthetic example 1

[0148]First, according to the method described in JP-A-2001-354735, compound 1 represented by the above formula (I) was synthesized.

[0149] That is, in a 500ml four-necked flask, add 235g bisphenol fluorene type epoxy resin (epoxy equivalent 235), 110mg tetramethylammonium chloride, 100mg2,6-di-tert-butyl-4-methylphenol and 72.0g acrylic acid. While blowing air thereinto at a rate of 25 ml / min, it was heated to 90 to 100° C. for dissolution. Next, the temperature was gradually raised while the solution was kept cloudy, and it was heated to 120° C. to completely dissolve it. At this time, the solution gradually became transparent and viscous, and stirring was continued as it was. Meanwhile, heating and stirring were continued until the measured acid value was less than 1.0 mgKOH / g. It takes 12 hours for the acid value to reach the target value. Then, it cooled to room temperature, and the bisphenol fluorene type epoxy acrylate represented by following formula (V) of the c...

Abstract

A photosensitive-resin layered product which, when used in forming a resinous black matrix, is excellent in sensitivity, light-shutting properties, thin-line adhesion, line-width stability in overdevelopment, transferability, and productivity. When used in forming color pixels, the photosensitive-resin layered product has high sensitivity. The photosensitive-resin layered product comprises a support layer and a photosensitive resin layer superposed thereon, wherein the photosensitive resin layer is made of a photosensitive resin composition comprising: 3-40 mass% alkali-soluble polymer represented by the following formula (I); 1-40 mass% specific alkali-soluble polymer; 3-25 mass% photopolymerizable compound having an ethylenically unsaturated double bond; 0.1-20 mass% photopolymerization initiator; and 40-70 mass% coloring pigment, the proportion of the alkali-soluble polymer represented by the formula (I) to the specific alkali-soluble polymer (mass ratio) being from 1:5 to 16:1.

Description

technical field [0001] The present invention relates to a photosensitive resin laminate useful for producing a substrate with a black matrix, a substrate with color pixels, and a color filter. Background technique [0002] In a liquid crystal display, there is generally a component called a color filter (Color filter) for coloring the backlight. A color filter consists of red, green, and blue colored pixels separated by a black matrix. In general, color pixels are required for colorization, and black matrices are arranged between color pixels in a grid pattern for purposes such as preventing TFT malfunction, improving contrast, and preventing color mixing. [0003] In addition, in recent years, liquid crystal displays are increasingly required to be of high quality. For example, in order to improve the color reproducibility of a display, it is required to increase the color purity (color purity) of a color pixel. If the color purity is increased, the transmittance of the ...
