Abstract
A decorative film is provided which has a heat-activatable transfer layer for affixation to a substrate to be decorated. The film includes a carrier sheet and a transfer layer in contact with the carrier sheet. The transfer layer includes a decorative layer and a heat-activatable adhesive layer for affixing the film to a substrate, wherein the heat-activatable adhesive layer is a solidified layer of a molten adhesive formulation. In a method of making such a decorative film, a thermoplastic adhesive formulation is heated to a temperature in excess of the softening temperature of the thermoplastic in the formulation to form a molten adhesive formulation, which is then applied to a decorative layer on the carrier sheet thereby forming a transfer layer having a transfer surface. The second surface of the carrier sheet and the transfer surface are chilled.
