Abstract: Provided are a coating film-forming composition for forming a coating film on a metal surface that exhibits excellent adhesiveness between a metal and a resin, and a surface-treated metal member having a coating film formed by using the composition. The coating film-forming composition is a solution containing a silane coupling agent having an amino group, a metallic ion and a halide ion. The metallic ion is preferably a copper ion, and a copper ion concentration in the solution is preferably 0.1 to 60 mM. The amount of Si based on the amount of Cu in the solution is preferably 30 or less, in terms of molar ratio. The pH of the solution is preferably 2.8 to 6.2.

Abstract: Provided is a chemical compound represented by the general formula (A), in which each of substituents Q1 to Q6 is bonded to a nitrogen atom of melamine backbone. In the general formula (A), at least one of Q1 to Q6 is X, and at least one of Q1 to Q6 is Y R1 is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms. R2 is a hydrogen atom, or a monovalent hydrocarbon group selected from the group consisting of an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 25 carbon atoms, and an aralkyl group having 7 to 30 carbon atoms. Each of R51 and R52 is a divalent organic group, and a is an integer of 1 to 3.
