Sheet of artificial leather made of polyvinyl chloride, the back of which is coated with a dry adhesive capable of being activated by heat, and use of this sheet for thermocovering of rigid articles

The process of thermocovering a rigid article comprised of a material selected from the group consisting of ABS resin, polyvinyl chloride, wood, wood mixtures, wood derivatives, and polyolefins with a sheet of polyvinyl chloride one side of which is coated with a dry adhesive capable of being activated by heat, the dry adhesive consisting of the product of reaction between a substantially linear hydroxypolyurethane derived from a polyester and a partially blocked aromatic triisocyanate in a proportion such that the dry adhesive has an isocyanate value of at least 100, the process comprising:

• contacting the rigid article with the side of the sheet of artificial leather which is coated with the dry adhesive while heating to a temperature effective to activate the dry adhesive to cause adhesion of the sheet to the rigid article.
