Embodiment

[0227] Next, an Example is given and this invention is demonstrated concretely. "%" and "part" in an example are mass % and a mass part, unless there is special mention.

Synthetic example 1

[0229] In a flask equipped with a stirrer, a thermometer, a reflux condenser, and a dropping funnel, flow nitrogen at 0.02 L / min to make a nitrogen atmosphere, add 257 parts by mass of propylene glycol monomethyl ether acetate, and heat to 70°C while stirring . Next, 8 parts of acrylic acid, 70 parts of N-cyclohexylmaleimide, 3,4-epoxytricyclo[5.2.1.0 2，6 ]decane-8-ylacrylate and 3,4-epoxytricyclo[5.2.1.0 2，6 ] Decane-9-base acrylate mixture (containing ratio is 50:50 in molar ratio) 32 mass parts are dissolved in 140 mass parts of propylene glycol monomethyl ether acetate to prepare solution, use dropping funnel through 4 The solution was added dropwise to a flask kept at 70° C. over several hours.

[0230] On the other hand, 15 parts by mass of the polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) was dissolved in 225 parts by mass of propylene glycol monomethyl ether acetate to obtain a solution, and another drop The liquid funnel was added dropwise to the ...

Synthetic example 2

[0233] An appropriate amount of nitrogen gas was flowed in a flask equipped with a reflux condenser, a dropping funnel, and a stirrer to replace it with a nitrogen atmosphere, and 371 parts of propylene glycol monomethyl ether acetate was added, and heated to 85° C. while stirring. Next, 54 parts of acrylic acid, 3,4-epoxytricyclo[52.1.0 2，6 ]decane-8-ylacrylate and 3,4-epoxytricyclo[5.2.1.0 2，6 ] 225 parts of a mixture of decane-9-yl acrylate (the molar ratio is 50:50), 81 parts of vinyl toluene (isomer mixture) are dissolved in 80 parts of propylene glycol monomethyl ether acetate and prepared A mixed solution was obtained, which was dropped into the flask over 4 hours.

[0234] On the other hand, 30 parts of the polymerization initiator 2,2-azobis(2,4-dimethylvaleronitrile) was dissolved in 160 parts of propylene glycol monomethyl ether acetate to obtain a solution, and the solution was added dropwise over 5 hours. . After dropping the initiator solution, it was kept at ...

Abstract

The invention provides a colored photopolymer composition containing colorant, resign, polymerism composition, polymerization initiator and solvent; the colorant comprises C.I. pigment green 58, yellow pigment, and at least one from a group formed by blue pigment, red pigment, purpose pigment and orange pigment; compared with total amount of solid constituent, content rate of the colorant is above 20 mass / % and below 50 mass / %.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition. Background technique [0002] The colored photosensitive resin composition is used for the production of a color filter used for display devices such as a liquid crystal display panel, an electroluminescence panel, and a plasma display panel. As such a colored photosensitive resin composition, there is known a composition containing C.I. Pigment Green 58, C.I. Pigment Yellow 138, and C.I. Pigment Red 177 as colorants, and the solid content of the colored photosensitive resin composition is The content of the coloring agent was 14% by mass (JP2011-118051-A). [0003] In the conventionally known colored photosensitive resin composition described above, when a colored patterned coating film is formed by a photolithography method, unexposed portions cannot be sufficiently removed by development, and residues and film residues may occur. Contents of the invention [0004] The p...
