Synthetic laminate structure and method for making same
摘要:
This invention relates to a synthetic laminate structure and a method for making the synthetic laminate structure. More particularly, the synthetic laminate structure contains an outer layer comprising a substantially transparent copolyester, a printed or colored film layer having opposed surfaces wherein at least one of the surfaces is colored or has an image printed thereon, a backing layer, and a laminating enhancer layer comprising a polyurethane disposed between the outer layer and the film layer, the laminated enhancer layer providing a bond between the outer layer and film layer characterized by a substantial absence of visible air pockets or adhesion discontinuities.
