Abstract
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.
Claims8
An indicia bearing elastomeric article comprising:
- an elastomeric layer having a lower surface bonded to said elastomeric article, said elastomeric layer having an upper surface bonded to a clear high melting point polyester thermoplastic layer, indicia comprising a sublimation dye carried in said polyester thermoplastic layer.
A heat activated indicia bearing sheet comprising:
- a thermoplastic elastomeric lower layer bonded to a primer coated clear polyethylene terephthalate upper layer by a polyester adhesive layer;
- said transfer further including indicia comprising sublimation dye carried in said clear polyethylene terephthalate upper layer.
