ABSTRACT:
A transfer sheet comprising a releasable substrate and a heat-foamable pattern, and preferably a further foaming inhibiting pattern formed thereon is prepared, and these patterns are transferred onto a foamable resin layer such as a polyvinyl chloride plastisol containing a blowing agent. The entire structure is heated, whereupon there is obtained a decorative article in which a resin layer, as a whole, has foamed, and at the same time, at the parts where the foamable resin pattern has been transferred, projecting convex parts are formed by the foaming of the heat-foamable pattern, while depressed concave parts are formed at parts onto which the foaming inhibiting pattern has been transferred.
