manufacture example 1

[0158] [Production Example 1] Production of Fluorinated Copolymer No.1

[0159] Add 100 g of ModiperF-600 (fluorine-containing copolymer, manufactured by NOF Corporation), 16.4 g of 1,2,3,6-tetrahydrophthalic anhydride and 400 g of propylene glycol-1-monomethyl ether-2- Acetate, stirred at 120°C until the peak of the acid anhydride disappeared, and obtained as the target fluorine-containing copolymer No.1 (mass average molecular weight: 33000, the acid value is 57.9mgKOH / g).

manufacture example 2

[0160] [Production Example 2] Production of Fluorinated Copolymer No. 2

[0161] Except for changing the polybasic acid anhydride to 20.7 g of trimellitic anhydride, the target fluorinated copolymer No. 2 was obtained as a propylene glycol-1-monomethyl ether-2-acetate solution in the same manner as in Production Example 1. (The mass average molecular weight is 33000, and the acid value is 116 mgKOH / g).

manufacture example 3

[0162] [Production Example 3] Production of Fluorinated Copolymer No.3

[0163] Except that the block copolymer is changed to ModiperF-220 (fluorine-containing copolymer, manufactured by NOF Corporation), and the polybasic acid anhydride is changed to 19.7 g of trimellitic anhydride, follow the same steps as in Production Example 1 with propylene glycol-1-monomethyl The target fluorinated copolymer No. 3 (mass average molecular weight: 36,000, acid value: 64.5 mgKOH / g) was obtained as an ether-2-acetate solution.

Abstract

Disclosed is an alkaline-developable photosensitive colored composition containing at least a binder resin, a fluorine-containing copolymer, a photopolymerization initiator, a colorant and a solvent. This alkaline-developable photosensitive colored composition is characterized in that a photopolymerizable unsaturated compound obtained by reacting an epoxy adduct (C), which is obtained by adding an unsaturated monobasic acid (B) to a polyfunctional epoxy resin (A), with a polybasic acid anhydride (D) is used as the binder resin.

Description

technical field [0001] This invention relates to the alkali developing type photosensitive coloring composition used for manufacture of the color filter used for a color liquid crystal display device, an imaging sensor, etc. Background technique [0002] Alkali-developing photosensitive coloring compositions containing an alkali-soluble binder resin having an ethylenically unsaturated bond, a photopolymerization initiator, a color material such as a pigment or a dye, and a solvent are widely used in the manufacture of color liquid crystal display devices, In the color filter of the main components such as imaging sensors. [0003] Generally, the manufacturing method of the color filter using an alkali-developing type photosensitive coloring composition is as follows. The alkali-developing photosensitive coloring composition containing a black coloring material is coated on a substrate, exposed through a photomask having a predetermined pattern, and developed to remove unexp...
