Abstract
A cathode-precipitating electrodeposition coating having excellent low-temperature curability, said composition consisting essentially of PA0 (A) 100 parts by weight of a high molecular compound having a molecular weight of 500 to 10,000 and containing carbon-carbon double bonds with an iodine value of 50 to 500 and 30 to 300 millimoles of amino groups per 100 g, PA0 (B) 10 to 200 parts by weight of a product of reaction of a diglycidyl compound represented by the general formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 represent a hydrogen atom or a methyl group and n represents an integer of from 0 to 20, with at least one organic acid component selected from the group consisting of PA1 (a) both an alpha,beta-unsaturated dicarboxylic acid and an alpha,beta-unsaturated monocarboxylic acid, (b) an unsaturated fatty acid containing at least 10% by weight of carbon-carbon conjugated double bonds and having a molecular weight of 100 to 350, and (c) an alpha,beta-unsaturated monocarboxylic acid, a 1,2-dicarboxylic acid anhydride, and a monoepoxy compound in this sequence, and PA0 (C) 0.005 to 1.0 part by weight as metal of a manganese salt of an organic acid or manganese dioxide.
