Abstract

A stoving lacquer comprises at least one organic solvent and a mixture containing (i) at least 30 wt. per cent of an alkyd resin from (a) a C8- 20 aliphatic monocarboxylic acid; (b) a mixture of C4- 10 dicarboxylic acids, 1 to 80% being, 1,2-dihydrophthalic acid; (c) a C3- 10 higher than dihydric alcohol; and optionally (d) a C4- 10 higher than dicarboxylic acid; and (e) a C2- 10 dihydric alcohol, and (ii) up to 70% of an "aminoplast resin." The term "aminoplast resin" is defined as including copolymers of N-alkoxymethyl amides of ethylenically unsaturated carboxylic acids as well as conventional etherified urea- or melamine-formaldehyde condensates but no specific example of the use of such co-polymers is given. The lacquers may include curing catalysts, flow promoters and other binders, e.g. epoxy resins. They may be used to lacquer metals, e.g. sheet metals. In the example the solvent is xylene and TiO2 pigment is included.ALSO:A stoving lacquer comprises an organic solvent and a mixture containing (i) at least 30 wt. % of an alkyd resin from (a) a C8-20 monocarboxylic acid; (b) a mixture of C4-10 dicarboxylic acids, 1 to 80% being 1,2 dihydrophthalic acid; (c) a C3-10 higher than dihydric alcohol; and optionally (d) a C4-10 higher than di-carboxylic acid; and (e) a C2-10 dihydric alcohol, and (ii) up to 70% of an "aminoplast resin".

In the Example the solvent is xylene and TiO2 pigment is included; the lacquer is sprayed onto degreased and derusted iron sheets.
