Synthetic example 1

[0440] [Synthesis Example 1: Synthesis of Specific Polymer (P-1)]

[0441] 171.2 g of ε-caprolactone, 8.6 g of methacrylic acid, and 0.2 g of 2,6-di-tert-butyl-4-methylphenol were introduced into a 500 mL three-necked flask, and stirred and dissolved while blowing nitrogen. 0.1 g of monobutyltin oxide was further added thereto, followed by heating to 100°C. Eight hours later, after confirming the disappearance of the raw material from the mixed liquid by gas chromatography, the mixture was cooled to room temperature, and 100 mL of N-methyl-2-pyrrolidone was added to dissolve the mixed liquid. 18.0 g of DBU was added thereto, and after stirring at room temperature for 30 minutes, 12.1 g of allyl bromide was further added.

[0442] Then, the mixed liquid was heated to 60° C., and after 6 hours, it was confirmed by gas chromatography that the raw materials had disappeared from the mixed liquid, and then cooled to room temperature. Then, the reaction mixture was poured into 1 L ...

[0447]228.2 g of ε-caprolactone, 8.6 g of methacrylic acid, and 0.2 g of 2,6-di-tert-butyl-4-methylphenol were introduced into a 500 mL three-necked flask, and stirred and dissolved while blowing nitrogen. 0.1 g of monobutyltin oxide was further added thereto, followed by heating to 100°C. Eight hours later, after confirming the disappearance of the raw materials from the mixed solution by gas chromatography, the mixture was cooled to room temperature, and 100 mL of N-methyl-2-pyrrolidone was added to dissolve it. 18.0 g of DBU was added thereto, and after stirring at room temperature for 30 minutes, 13.1 g of epibromohydrin was further added.

[0448] Then, the mixed liquid was heated to 50° C., and after 6 hours, it was confirmed by gas chromatography that the raw materials had disappeared from the mixed liquid, and then cooled to room temperature. The reaction mixture was poured into 1 L of water to preci...

Abstract

The present invention provides a pigment disperse combination, a coloring photosensitive combination, a color filter, a liquid crystal display element and a solid camera shooting element; the pigmentdisperse combination is capable of dispersing minute pigment in a manner of one particle, has an excellent disperse stability and may be formed coloring tunica with an excellent contrast grade; the coloring photosensitive combination contains the pigment disperse combination, has an excellent curing sensitivity, and may be formed high strength coloring curing membrane with an excellent contrast grade. The pigment disperse combination of the invention is characterized in that the pigment disperse combination contains (a) a high molecular compound, (b) a pigment and (c) an organic solvent, the high molecular compound contains at least one repetitive unit of repetitive units represented by formula (I) and formula (II), in the formula (I) and (II), R<1>-R<6> represent hydrogen atom and the like, X<1> and X<2> represent -CO- and the like, L<1> and L<2> represent two-valency organic linking groups and the like, Y<1> represents an oxygen atom and the like, Y<2> represents -C(=O)O- and the like, Z<1> and Z<2> represent groups containing a C-C double bond, m and n represent integers from 2 to 8, and p and q represent integers from 1 to 100.

Description

technical field [0001] The present invention relates to a pigment dispersion composition, a colored photosensitive composition containing the pigment dispersion composition, a color filter having a colored region formed from the colored photosensitive composition, a liquid crystal display element using the color filter, and Solid-state imaging element. Background technique [0002] The color filter is manufactured as follows: A colored photosensitive composition is prepared by containing a pigment dispersion composition obtained by dispersing an organic pigment or an inorganic pigment, a multifunctional monomer, a polymerization initiator, an alkali-soluble resin, and other components. , using the composition to form a colored pattern by a photolithography method, an inkjet method, or the like. [0003] In recent years, color filters tend to be used not only in monitors but also in televisions (TVs) in liquid crystal display (LCD) applications. As the use tends to expand, ...
