Decorative glass laminate containing an ultraviolet printed image thereon and a method for preparing said decorative glass laminate
View Patent ↗This invention is directed to a plastic composite comprising color images printed onto a polymeric support film using UV ink. The polymeric support film layer may be bonded to a polymeric film selected from the group consisting of aliphatic polyurethane and ethyl vinyl acetate. The combined laminate can then optionally be 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. Preferably, when the UV image is printed on the polymeric support film, the image is only partially cured by a UV lamp. After the polymeric support film is contacted with the polymeric film, with the partially cured UV image therebetween, the laminate is exposed to a second UV lamp operating at full power so as to completely cure the UV image.
