Thermally curable resin composition for protective film

摘要

The present invention provides an overcoat film which has excellent degree of planarization by optimizing the molecular weight of a binder resin included in a thermally curable resin composition for a protective film and the content of each component including the same. In a color filter according to the present invention, it is not necessary to light up all the red, green, and blue (RGB) pixels for eliciting a white light and perform a separate application process of a white portion because an overcoat film according to the present invention may serve as the white portion.

主权项

1. A thermally curable resin composition, comprising:
about 1 to about 28% by weight of a binder resin; about 68 to about 95% by weight of a polyfunctional monomer; and about 4 to about 31% by weight of other additives comprising a thermal polymerization initiator, a curing agent, an adhesion promoting agent, and a surfactant based on a total weight of solid content of the composition, wherein the binder resin is a copolymer of an epoxy group-containing unsaturated compound and an ethylenic unsaturated compound, the ethylenic unsaturated compound comprises a styrene monomer, an ethylenic unsaturated compound having a functional group exhibiting acidity by hydrolysis and an ethylenic unsaturated compound having a silyl group, and wherein the curing agent is one or more selected from the group consisting of phthalic acid anhydride, tetra-hydrophthalic acid anhydride, hexa-hydrophthalic acid anhydride, methyltetra-hydrophthalic acid anhydride, methylendomethylene tetra-hydrophthalic acid anhydride, hexachloroendomethylene tetra-hydrophthalic acid anhydride, dodecyl succinic acid anhydride, and trimellitic acid anhydride.
