COLOR FILTER INK, COLOR FILTER, IMAGE DISPLAY DEVICE, AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide inkjet-type color filter ink which can be stably and suitably used to manufacture a color filter which reduces color unevenness and density unevenness in each part and has superior durability and superior uniformity of characteristics between color filters.

SOLUTION: The color filter ink which is used to manufacture such a color filter by an inkjet method, includes a colorant, a liquid medium in which the colorant dissolves and/or disperses, and a curable resin material. The liquid medium has a characteristic in which, when a cured urethane-based adhesive material is put into the liquid medium under a sealed condition in an environment at an atmospheric pressure and 40°C and left for ten days, the swelling ratio of the cured urethane-based adhesive material is ≤130%. The liquid medium includes a compound containing at least one of a ≥4C alkoxyl group and an acetyl group at the end of a molecule chain. The curable resin material includes a polymer A containing at least an epoxy-containing vinyl monomer as a monomer component.
