Abstract
Abstract A method for manufacturing a color filter comprises a step for charging an ink comprising a thermosetting resin composition onto an opening of a black matrix provided on a transparent substrate and a step for curing the ink by heat treatment. The thermosetting resin composition comprises either a coloring agent, a multifunctional epoxide having at least two glycidyl groups and a compound crosslinked by the multifunctional epoxide; or a coloring agent, a cellulose-reactive compound and a compound crosslinked by the cellulose-reactive compound.
