  • Digital color-design composite for use in laminated glass
    Patent number: 6824868
    Abstract: This invention is directed to a plastic composite comprising color images printed onto a polyethylene terephthalate (PET) substrate using thermal transfer (TT) printing technology. The PET layer is then bonded to a second PET layer using a thermally activated adhesive, preferably ethylene vinyl acetate copolymer (EVA). The bonded PET layers are then disposed between two layers of plasticized PVB, forming the plastic composite. The plastic composite can then be placed between two sheets of glass forming the final laminated glass product.
