Abstract

PURPOSE: To provide a coated steel sheet which has excellent film performance and can be bonded to each other by using an adhesive, by providing an epoxy primer coat layer and the baked film layer of a mixture composed of an acrylic copolymer and an amino resin on a steel sheet.
CONSTITUTION: At least 3wt% carboxyl group-contg. monomer (a) such as acrylic acid, 3W30wt% hydroxyl group-contg. monomer (b) such as β-hydroxyethyl acrylate, not more than 94wt% (meth)acrylate (c), such as isobutyl acrylate, copolymerizable with components (a) and (b), and 0W50wt% other monomer such as styrene, are copolymerized to produce an acrylic copolymer. Then an epoxy primer is coated in a film thickness of 1W5μ on a steel sheet. On the primer film layer there is formed a baked coated film layer (in a thickness of 5W40μ) of a mixture composed of 50W90wt% above copolymer and 50W10wt% amino resin to obtain a coated steel sheet.
