POLYMER CONTAINING CARBOXYL GROUP AND AMINO GROUP, THERMOSETTING INKJET INK COMPOSITION FOR COLOR FILTER, AND THE RESULTANT COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a polymer containing carboxyl groups and amino groups capable of making the crosslink density of a cured resin layer higher, high in hardness, excellent in the dispersibility of micronized pigment, and eluting no pigment in the process following post-baking and a pixel formation such as oriented film formation, to provide a thermosetting inkjet ink composition for color filter, and to provide the resultant color filter.

SOLUTION: The polymer containing carboxyl groups and amino groups is represented by a structure of formula (1), having a number-average molecular weight of 3,000-50,000; wherein the molar fractions of k, m and n are 5-20 mol%, 60-90 mol% and 5-20 mol% respectively in formula (1) (wherein, R1, R2and R4are each H or methyl; R3is 6-12C cyclic hydrocarbon group; R5is 1-8C alkylene; and R6and R7are each 1-3C alkyl).
