Laminate having improved dimensional stability and heat resistance

A laminate comprising (A) a thermosetting resin-impregnated prepreg layer constituting a surface layer, (B) a rubber or thermoplastic resin layer having a good flexibility and (C) a hot melt resin adhesive layer, said hot melt resin adhesive layer being interposed between said thermosetting resin-impregnated prepreg layer and said rubber or thermoplastic resin layer;

• wherein said layer (A) is a prepreg impregnated with a thermosetting resin selected from a diallyl phthalate resin or an unsaturated polyester;
• the rubber or resin of the layer (B) is a rubber or a thermoplastic resin selected from chlorinated polyethylene or polyvinyl chloride;
• and said hot melt resin adhesive layer (C) comprises a hot melt resin having a melting point of 60.degree. to 165.degree. C. and a solubility parameter (SP value) of 7.4 to 10.9, selected from an ethylene-vinyl acetate copolymer, an ethylene-acrylic acid copolymer, carboxylated polyethylene, polyurethane, polybutylene terephthalate and a modified ethylene-vinyl acetate copolymer, and wherein said hot melt resin adhesive layer (C) is formed by applying or laminating said hot melt resin on both surfaces of a reinforcing core material comprising a metal foil, a punching metal foil or a plain weave net made of ribbon metal yarns, said reinforcing core material having a thickness of 10 to 200 .mu.m, said metal being selected from the group consisting of aluminum, iron, copper, zinc and lead.
