<p>PROBLEM TO BE SOLVED: To impart satisfactory anti-corrosion property and adhesive property with lacquer with simple pretreatment of metal by forming an adhesive layer of a metal board having an anti-corrosion adhesive layer containing adhesive polymer of organic compound base out of adhesive polymer containing a specific polybismaleimide. SOLUTION: A metal plate of steel, aluminum, zinc, plated steel or magnesium is cleaned with ethyl acetate, then coated with solution of bismaleimide mixture dissolved in dioxane, dried, then covered with polyurethane acrylate cover lacquer, and dry cured to form a bismaleimide layer. The polybismaleimide in the layer is formed of homopolymer or copolymer of the bismaleimide and/or maleimide end oligomer and/or maleimide end polymer; and/or copolymer with organic compound containing a functional group polymerizable with compound.</p> |
