A heat activated transfer which is particularly suitable for marking elastomeric articles comprises a lower elastomeric layer bonded to an upper polyester layer. The upper polyester layer in turn carries indicia which is a sublimation dye heat transferred into the polyester layer. The polyester is preferably a high temperature saturated polyester resin, preferably polyethylene terephthalate. The lower layer is preferably a thermoplastic elastomeric layer. The two layers are bonded together by a thermoplastic adhesive, preferably a polyester.
