Claim:
1. A film-forming composition characterized by comprising a triazine ring-containing hyperbranched polymer which includes a recurring unit structure of formula (1) below and an aromatic polyamide-based hyperbranched polymer which includes a recurring unit structure of formula (2) below wherein R 1 to R 4 are each independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aralkyl group, Ar is at least one moiety selected from the group consisting of moieties of formulas (3) to (14) and A is at least one moiety selected from the group consisting of moieties of formulas (3) to (27) in which R 5 to R 85 are each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfonic acid group, an alkyl group of 1 to 10 carbons which may have a branched structure, or an alkoxy group of 1 to 10 carbons which may have a branched structure; R W X wherein R 103 to R 106 are each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfonic acid group, an alkyl group of 1 to 10 carbons which may have a branched structure, or an alkoxy group of 1 to 10 carbons which may have a branched structure; and Y 1 and Y 2 are each independently a single bond or an alkylene group of 1 to 10 carbons which may have a branched structure; and n is an integer from 1 to 20, wherein the aromatic polyamide-based hyperbranched polymer is obtained by reacting a benzenetricarboxylic acid or a derivative thereof with a diamine compound in the presence of at least a monofunctional substance having one functional group capable of reacting with the benzenetricarboxylic acid or a derivative thereof.
