(57) [Abstract] [Purpose] It is possible to store at room temperature without the need for refrigeration equipment, and to maintain the viscosity and the development speed and resolution of the coating stable over a long period (2 months or more). Provided is an ink for an alkali development type photosensitive color filter, and a color filter having high dimensional accuracy of a pixel portion formed using the ink and excellent in color reproducibility. [Structure] (A) The following general formula (1): An unsaturated group-containing compound obtained by reacting a compound mainly composed of epoxy (meth) acrylate represented by: with a polybasic acid or an acid anhydride thereof, and (B) a photopolymerization initiator or a sensitizer, (C) Pigment, and the ratio of the B component and the C component is 0.1 to 100 parts by weight of the A component, respectively. The color filter ink is 30 parts by weight and 10 to 200 parts by weight, and the ratio of the epoxy compound having an epoxy group is 4 parts by weight or less and is excellent in storage stability. A color filter manufactured using such a color filter ink. |
