Patent ID: 8652755

Claim:
A positive photosensitive resin composition comprising: a component (A) comprising an acrylic polymer obtained by polymerizing a monomer mixture that contains a monomer having an acid dissociable group, a monomer having an aliphatic hydroxyl group, and an N-substituted maleimide monomer; a component (B) comprising an acrylic polymer containing an acid dissociable group and a blocked isocyanate group; a component (C) comprising an acrylic polymer containing an acid dissociable group, an aliphatic hydroxyl group, a C 3-10 fluoroalkyl group, and a silyl ether defined by the formula: —X 4 —Si(O—SiX 1 X 2 X 3 ) 3 where X 1 , X 2 , and X 3 are independently a C 1-3 alkyl group, and X 4 is a C 1-6 alkylene group; and a component (D) comprising a photoacid generator.
