Hardenable synthetic resin mixtures

Claim 1

A coating or printing composition comprising a non-aromatic solvent or solvent mixture and, as a binder, a hardenable synthetic resin mixture comprising (A) a glycidyl compound having more than one epoxy group per molecule and an epoxy value from 0.4 to 0.7; (B) a solid synthetic resin component having free amino groups which is an adduct formed between (1) an excess of a polyaminoamide in turn formed between (a) a dimeric fatty acid, (b) ethylenediamine, and (c) a diamine which is a member selected from the group consisting of aliphatic diamines having from 3 to 20 carbon atoms, such aliphatic amines wherein the carbon chain is interrupted by at least one oxygen atom to form an oxa-compound, cycloaliphatic diamines having 5 or 6 ring members, and heterocyclic diamines having 5 or 6 ring members, and (2) a glycidyl compound having more than one epoxy group per molecule and an epoxy value from 0.4 to 0.7, in which resin component (B) the ratio of (B)(1)(b) to (B)(1)(c) may range from 0.95:0.05 to 0.5:0.5 and from 0.05 to 0.30 equivalent of amine hydrogen atoms of polyaminoamide (B)(1) have been preadducted by reaction with glycidyl compound (B)(2); and (C) a solid polyamide formed between (1) a dimeric fatty acid, (2) ethylenediamine, and (3) a diamine which is a member selected from the group consisting of aliphatic diamines having from 3 to 20 carbon atoms, such aliphatic amines wherein the carbon chain is interrupted by at least one oxygen atom to form an oxa-compound, cycloaliphatic diamines having 5 or 6 ring members, and heterocyclic diamines having 5 or 6 ring members, and (4) a short chain, linear aliphatic monocarboxylic acid in an amount from 0.4 to 0.8 equivalent, based on the total acid equivalents, in which polyamide (C) the equivalent ratio of (C)(1) to (C)(2) is from 1.0:0 to 0.5:0.5 and substantially equivalent amounts of an acid component comprising compounds (C)(1) and (C)(4) and of a basic component comprising amino compounds (C)(2) and (C)(3) are reacted to form said polyamide (C), in which mixture (A) and (B) are present in substantially equivalent amounts and the weight ratio (A)+(B):(C) is from 9:1 to 1.5:1.
