PURPOSE:To obtain a laminated sheet having excellent adhesion to ultraviolet- curable ink, by laminating substrates impregnated with a resin contg. pentabromodiphenyl ether and molding the laminate. CONSTITUTION:100pts.wt. thermosetting resin such as phenolic resin, epoxy resin or unsaturated polyester resin and 2-60pts.wt. pentabromodiphenyl ether are dissolved in such a proportion as to give 1-30pts.wt. latter per 100ts.wt. varnish, thus obtaining varnish. A substrate such as paper, glass or (non)woven fabric is impregnated with said varnish to obtain a resin-impregnated substrate. Optionally, a metallic foil such as copper foil is laminated thereon. One to several sheets of said substrates are laminated and the laminate is molded by heating under pressure.
