Abstract The present invention is a method of applying a heat activated transfer to a cloth substrate. The transfer includes a thermoplastic adhesive layer and printed thereon a thermoset ink layer. The thermoset ink layer is discontinuous leaving exposed areas of thermoplastic material. The transfer is applied by setting the thermoplastic layer against a substrate, such as a cloth shirt, placing a piece of blotting paper or other absorbent material above the transfer in contact with the thermoset layer and applying heat and pressure forcing the thermoplastic material to melt. The thermoplastic material which contacts the blotting material is absorbed by the blotting paper whereas the thermoplastic material covered with the thermoset ink absorbs into the substrate bonding the thermoset ink to the substrate providing an emblem or the like. The invention also includes the article itself which is a heat activated transfer including a continuous thermoplastic layer and a discontinuous thermoset layer leaving voids in between the portions of the thermoset material.
A method of applying a heat activated transfer to a substrate wherein the transfer comprises a continuous thermoplastic adhesive layer and an upper discontinuous heat resistant layer bonded to said thermoplastic adhesive layer with said transfer positioned on said substrate with said thermoplastic adhesive layer against said substrate and an absorbing sheet positioned against said upper layer, said absorbing sheet being effective to absorb said thermoplastic adhesive when said adhesive is molten; said method comprising (a) applying heat and pressure against said absorbing sheet towards said substrate thereby softening said thermoplastic layer; and (b) pressing said transfer against said substrate whereby the portion of said thermoplastic layer not underneath said heat resistant layer is absorbed by said absorbing sheet; (c) separating said absorbing sheet from said thermoset layer whereby a second portion of said thermoplastic layer underneath said heat resistant layer remains, bonding said heat resistant layer to said substrate.
