PURPOSE: To provide a coating compsn. for precoating, excellent in hardness, film performance, and fabrication, by mixing two kinds of linear polyesters having particular formulations, methoxymelamine compds., and butoxymelamine compds. n CONSTITUTION: 40W97wt% linear polyester (A) composed of an acid component consisting of 20W80mol% terephthalic acid and 80W20mol% isophthalic acid, with a glycol component consisting of 20W80mol% ethylene glycol and 80W 20mol% neopentyl glycol, 40W97wt% linear polyester (B) composed of an acid component consisting of 20W80mol% terephthalic acid, 19W0mol% isophthalic acid, and 40W20mol% aliphatic dicarboxylic acid, with the same glycol component as in component A, 1W59wt% methoxymelamine compd. (c), and 1W 59wt% butoxymelamine compd. (D) are mixed to yield the intended coating compsn. n COPYRIGHT: (C)1984,JPO&Japio |
