UV curable coating compositions, abrasion resistant UV stabilized thermoplastic composites and method

U.S. Patent Number: 5227240

Abstract: Organophosphorus compounds capable of being activated with light at from 360 nm to about 410 nm, such as, an acylphosphine oxide, have been found useful as photoinitiators for effecting the cure of various UV curable coating compositions, such as a UV curable organic material in the presence of up to 20% by weight of a UV absorber. UV stabilized thermoplastic composites of films, sheets, or laminates having thickness of up to an inch or more with improved optical clarity also are provided.
