PURPOSE: To provide titled compsn. which forms a coating film having excellent smoothness, gloss, brilliancy and weathering resistance, consisting of a dibasic acid and a vinyl copolymer contg. a glycidyl gp.-contg. vinyl monomer and a phosphated vinyl monomer as copolymer components. n CONSTITUTION: (II) An aliph. dibasid acid (e.g. sebacic acid) and, if necessary, a curing reaction catalyst (e.g. an amine) and an epoxy resin are blended with (I) a vinyl copolymer having a number-average MW of 1,500W30,000 and a softening point of 80W150°C, consisting of (i) 5W50wt% of a glycidyl gp.-contg. vinyl monomer (e.g. glycidyl acrylate), (ii) 0.001W10wt% of a phosphated vinyl monomer (e.g. phosphoric monoester of β-hydroxyethyl acrylate) and (iii) 94.999W40wt% of another vinyl monomer to obtain the desired powdered paint. The paint is coated on a steel plate, etc. by electrostatic coating, fluidization dip coating, etc. and baked to form a coating film. n COPYRIGHT: (C)1981,JPO&Japio |
