Claim Text:
1. A film-forming composition comprising: (A) a triazine ring-containing polymer which comprises a recurring unit structure of formula (1) below: wherein R and R′ are each independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aralkyl group; and Ar is at least one moiety selected from the group consisting of moieties of formulas (2) to (13) below: wherein R 1 to R 92 are each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfone group, an alkyl group of 1 to 10 carbons, or an alkoxy group of 1 to 10 carbons; R 93 and R 94 are hydrogen atoms or alkyl groups of 1 to 10 carbons; W 1 and W 2 are each independently a single bond, CR 95 R 96 (wherein R 95 and R 96 are each independently a hydrogen atom or an alkyl group of 1 to 10 carbons, with the proviso that R 95 and R 96 may together form a ring), C═O, O, S, SO, SO 2 or NR 97 (wherein R 97 is a hydrogen atom or an alkyl group of 1 to 10 carbons); and X 1 and X 2 are each independently a single bond, an alkylene group of 1 to 10 carbons, or a group of formula (14) below: wherein R 98 to R 101 are each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfone group, an alkyl group of 1 to 10 carbons, or an alkoxy group of 1 to 10 carbons; and Y 1 and Y 2 being each independently a single bond or an alkylene group of 1 to 10 carbons; (B) a crosslinking agent; and 1 to 200 parts by weight of (C) an organic monomer capable of providing a linear polymer, wherein the organic monomer is a compound of formula (A) below wherein R 102 and R 104 are each independently a hydrogen atom, an alkyl group of 1 to 10 carbons or a polymerizable carbon-carbon double bond-containing group; and R 103 being a hydrogen atom or an alkyl group of 1 to 10 carbons, with the proviso that either of R 102 and R 104 is a polymerizable carbon-carbon double bond-containing group but R 102 and R 104 are not both at the same time polymerizable carbon-carbon double bond-containing groups, per 100 parts by weight of said triazine-ring containing polymer (A), wherein said film-forming composition is solvent-free.
