ABSTRACT:
A linear polyester comprising residues of an acid component comprising 45 to 55 mole percent of a residue of terephthalic acid or its esterifieable derivatives; 35 to 45 mole percent of a residue of another aromatic dicarboxylic acid or esterifiable derivatives; 0 to 20 mole percent of a cycloaliphatic and/or aliphatic dicarboxylic acid; and residues of an alcohol component comprising 20 to 30 mole percent of a residue of hydroxypivalic acid neopentyl glycol ester; 20 to 30 mole percent of a residue of an aliphatic diol with a branched carbon atom; 40 to 60 mole percent of a residue of ethylene glycol of which up to 10 mole percent can be replaced by ether diols or by diprimary aliphatic diols of more than two carbon atoms in the chain; a coating composition containing moieties of terephthalic acid which is soluble without turbidity and soluble at room temperature further containing moieties of an aminoplastic resin, a coating composition comprising 10 to 25 weight percent aminoplastic resin and 75 to 90 weight percent of the above-named linear polyester; and the use of such coating composition in the coating of sheet metal substrates.
