1. A method for making a decorative film having a heat-activatable transfer layer for affixation to a substrate to be decorated, comprising:

  • (a) providing a carrier sheet having a decorative layer applied to a first surface of the carrier sheet;

    (b) heating a heat-activatable thermoplastic adhesive formulation to a temperature in excess of a softening temperature of a thermoplastic in the formulation such that the adhesive formulation is molten;

    (c) applying a layer of the molten thermoplastic adhesive formulation on the decorative layer thereby forming a heat-activatable transfer layer on top of the carrier sheet, wherein the transfer layer comprises the decorative layer and the layer of the adhesive formulation, the transfer layer having a transfer surface for affixation to a substrate and said transfer layer and said carrier sheet form a decorative film; and

    (d) chilling said decorative film such that the decorative film comprises a solidified layer of a molten adhesive formulation, wherein said molten adhesive formulation is solvent-free.
