A color filter including a transparent substrate, a colored layer on the substrate, and a protective layer on the colored layer. The protective layer is the product formed by exposing, developing, and heating a coating containing an epoxy-containing copolymer resin having 0 to 55% by mole of formula (1), 5 to 95% by mole of formula (2), and 5 to 95% by mole of formula (3), the formula (1) units having been partially reacted, through carboxyl groups, with a (meth)acryloylalkyl isocyanate compound, the formula (2) units having been partially reacted, through hydroxyl groups, with a (meth)acryloylalkyl isocyanate compound, the copolymer resin containing 5 to 95% by mole of (meth)acryloyl groups, an acid value of 0 to 400 mg KOH/g, and a weight average molecular weight of 5,000 to 1,000,000: |
