ABSTRACT:
A yellow-resistant vinyl film laminate comprising a plasticized polyvinylchloride layer and a UV cured top which contains active UV-activatable, free radical-generating species, wherein the free radical-generating species and the plasticizer are sufficiently immiscible so as to avoid reactions in the presence of UV light which produce yellowing of the polyvinylchloride layer.
