PHOTOSENSITIVE RESIN COMPOSITION AND USES THEREOF

摘要

The invention relates to a photosensitive resin composition for black matrix, a color filter formed by the black matrix, and a liquid crystal display element. The photosensitive resin composition comprises an alkali-soluble resin (A), a compound containing an ethylenically unsaturated group (B), a photoinitiator (C), a solvent (D), a black pigment (E), and a compound (F) containing Formula (1). The photosensitive resin composition for black matrix has the advantage of good linearity of pattern with high finesse.

1. A photosensitive resin composition comprising:
an alkali-soluble resin (A); a compound (B) containing an ethylenically unsaturated group; a photoinitiator (C); a solvent (D); a black pigment (E); and a compound (F) having a structure represented by Formula (1); wherein: the alkali-soluble resin (A) comprises a resin (A-1) having an unsaturated group, and the resin (A-1) having the unsaturated group is obtained by polymerizing a mixture comprising an epoxy compound (a-1-1) containing at least two epoxy groups, and a compound (a-1-2) containing at least one carboxylic acid group and at least one ethylenically unsaturated group; in Formula (1), R′ is selected from the group consisting of a hydrogen atom, a substituted or unsubstituted C1-C20 hydrocarbon group and a substituted or unsubstituted C1-C20 acyl group; each R′ is the same or different; R″ is selected from the group consisting of a hydrogen atom, a substituted or unsubstituted C1-C15 hydrocarbon group, a substituted or unsubstituted C1-C15 acyl group and a substituted or unsubstituted C1-C15 nitro group; each R″ is the same or different; s represents 0, 1 or 2; and W represents  wherein, Z represents a hydrogen atom or a C1-C4 alkyl group.
