PURPOSE:To provide a rigid vinyl chloride resin sheet which is used for covering a steel sheet, retains its surface pattern without being adversely affected even under load, and is excellent in processibility in covering the steel sheet. CONSTITUTION:This resin sheet, which is bonded to the surface of a metal sheet such as a steel or aluminum sheet, is obtd. from a rigid vinyl chloride resin compsn. obtd. by compounding 100 pts.wt. vinyl chloride-vinyl acetate copolymer resin having a vinyl acetate content of 3-15wt.% as the base resin, up to 3 pts.wt. plasticizer, and 10-20 pts.wt. methyl methacrylate-butadiene- styrene terpolymer. |
