ABSTRACT:
A composite vehicle-interior finish material having high adhesive strength and excellent heat resistance is composed of three layers, namely, a first layer formed of a polyvinyl chloride sheet or leather, a second layer formed by impregnated and coating a soft foam with a vinylidene chloride-based copolymer latex composed of 64-95 wt. % of vinylidene chloride monomer, 4-35 wt. % of at least one vinyl monomer other than vinylidene chloride monomer and 1-10 wt. % of an unsaturated organic acid monomer and then drying the soft foam, and a third layer formed by coating a base material with the vinylidene chloride-based copolymer latex and then drying the base material. These three layers have been bonded together by high-frequency welding.
