    摘要: A multilayer coating is produced on a substrate by a process in which an aqueous dispersion containing(A) a carbonyl-containing copolymer of monoolefinically unsaturated compounds, not less than 10% by weight of which have carbonyl groups which react with hydrazide groups, and(B) polyhydrazides,is applied as a base coat to the substrate, the water is flashed off and one or more further conventional coats are applied to this base coat as a dispersion or solution, the solvent is flashed off and, if required, the resulting multilayer coating is baked for from 10 to 60 minutes at from 70.degree. to 180.degree. C.

    摘要: Coated substrates include a metal substrate and a polytriazole polymer applied to a surface of the metal substrate. The polytriazole polymer may include substituted phenyls, substituted benzyls, or both substituted phenyls and substituted benzyls. The substituted phenyls and the substituted benzyls may be independently substituted with hydrogen, bromo, fluoro, chloro, iodo, hydroxy, methyl, trifluoromethyl, dimethylamino, tert-butyl, carboxyl, triphenylmethyl, tris(4-fluorophenyl)methyl, tris(4-methylphenyl)methyl, (4-hydroxyphenyl)diphenylmethyl, and difluoromethoxy groups. The polytriazole polymer may have a degree of polymerization from 50 to 400.
