Abstract:
1. A composition for forming anti-reflective coating, the composition comprising: a triazine trione oligomer compound having hydroxyalkyl structure as substituent on nitrogen atom, a triazine trione polymer compound having hydroxyalkyl structure as substituent on nitrogen atom or a mixture thereof; wherein the triazine trione oligomer compound having hydroxyalkyl structure as substituent on nitrogen atom, or the triazine trione polymer compound having hydroxyalkyl structure as substituent on nitrogen atom is a triazine trione oligomer compound, triazine trione polymer compound, or mixture thereof having a structure in which at least two triazine trione rings are linked through a linking group of formula (4) or (5) on the nitrogen atoms: wherein A 1 , A 2 and A 3 are independently of one another hydrogen atom, methyl or ethyl, each Y is independently a direct bond or —C(═O)—, Ar is benzene ring or naphthalene ring which may be substituted with C 1-6 alkyl, phenyl, naphthyl, halogen atom, C 1-6 alkoxycarbonyl, nitro, carboxy, cyano, C 1-6 alkoxy, hydroxy, thiol, C 1-6 alkylthio or amino, Q is C 1-6 alkyl, C 5-8 cycloalkyl, Ar or —CH 2 —Ar—CH 2 —, R 1 is C 1-6 alkyl, phenyl or benzyl, and a crosslinking agent having at least two crosslink-forming substituents.
