ABSTRACT:
A polymer composition is provided comprising an ultraviolet light sensitive phosphite and an amount of a polyamine effective to enhance the resistance of the color formation upon exposure to ultraviolet light. A process is also provided for applying ink to a thermoplastic substrate involving ultraviolet light curing of the ink. The thermoplastic compositions are useful for making article which contain UV sensitive phosphites for oxidative stability and also exhibit resistance to ultraviolet light yellowing of the phosphite. The inking process resists detrimental yellowing of the composition upon exposure to high levels of ultraviolet light radiation.
