Abstract
The present invention relates to one-solution type thermosetting resin composition for a protective film of a color filter, and a color filter including the same. The one-solution type thermosetting resin composition includes a copolymer (A) including (meth)acrylate with an epoxy cyclic structure at the side chain, (meth)acrylate with a hydroxyl terminal, acid anhydride, and maleimide with a substituent; an epoxy resin (B); a base-generating agent (C); and an organic solvent (D). When a protective film of a color filter is prepared by using the one-solution type thermosetting resin composition according to the present invention, it has excellent storage stability as well as excellent flatness, close-contacting property, transmission properties, heat resistance, and chemical resistance.
