Patent ID: 7776504

Claim:
A resist composition comprising a resin (A) selected from the group consisting of polyvinyl phenol or a copolymer thereof, a photoacid generator or a photobase generator (B), a crosslinking compound (C) and a dye mixture (D) containing a dye having a structure of amino sulfonate ester or ammonium sulfonate salt in a proportion of 40 to 95% by weight of total dye content, wherein the resist composition has an optical quality having at least a region with a transmittance of 70% or more and a region with a transmittance of 10% or less in wavelength range between 400 nm and 700 nm, and in which a variation in transmittance is 5% or less even when the composition is subjected to a temperature of 200° C. or more, wherein the dye mixture (D) is present in the resist composition in an amount of 55 to 95% by weight based on total solid content, and wherein the dye having a structure of amino sulfonate ester or ammonium sulfonate salt is a dye selected from the group consisting of: wherein R is an alkyl or aromatic group and R′ is a hydrogen atom or an alkyl group.
