Abstract
Abstract An exterior automotive vehicle component which is provided for exterior appearance purposes or is of such large size as to materially contribute to the exterior appearance of the vehicle. The component comprises a substrate of thermoplastic polyolefin composition defining the shape of the component having pigmentation therein defining the color of the exterior surface means and a coating of clear material on the exterior surface of the substrate enabling the exterior color and configurational appearance to have an enhanced luster and improved mar resistance. The composition has an ultraviolet radiation deterioration preventing agent therein and the clear material has an ultraviolet radiation screening agent therein. The amount of ultraviolet radiation screening in the clear material cooperating with the amount of ultraviolet radiation deterioration preventing agent in the composition such as to provide a level of resistance to UV deterioration acceptable in the exterior vehicular environment of the component while accommodating a tenacity of adherence in the exterior vehicular environment of the component.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
179 words
An exterior automotive vehicle component which is provided for exterior appearance purposes or is of such large size as to materially contribute to the exterior appearance of the vehicle comprising a substrate of thermoplastic polyolefin composition defining the shape of the component, said substrate having exterior surface means defining the exterior configurational appearance of the component, said composition having pigmentation therein defining the color of said exterior surface means, a coating of clear material on said exterior surface means enabling the exterior color and configurational appearance to have an enhanced luster and mar resistance, said composition having an ultraviolet radiation deterioration preventing agent therein, said clear material having an ultraviolet radiation screening agent therein, the amount of ultraviolet radiation screening agent in said clear material cooperating with the amount of ultraviolet radiation deterioration preventing agent in said composition such as to provide a level of resistance to UV deterioration acceptable in the exterior vehicular environment of the component while accommodating a tenacity of adherence of the coating to the substrate acceptable in the exterior vehicular environment of the component.
Claim 2
Dependent Claim
179 words
An exterior automotive vehicle component which is provided for exterior appearance purposes or is of such large size as to materially contribute to the exterior appearance of the vehicle comprising a substrate of thermoplastic polyolefin composition defining the shape of the component, said substrate having exterior surface means defining the exterior configurational appearance of the component, said composition having pigmentation therein defining the color of said exterior surface means, a coating of clear material on said exterior surface means enabling the exterior color and configurational appearance to have an enhanced luster and mar resistance, said composition having an ultraviolet radiation deterioration preventing agent therein, said clear material having an ultraviolet radiation screening agent therein, the amount of ultraviolet radiation screening agent in said clear material cooperating with the amount of ultraviolet radiation deterioration preventing agent in said composition such as to provide a level of resistance to UV deterioration acceptable in the exterior vehicular environment of the component while accommodating a tenacity of adherence of the coating to the substrate acceptable in the exterior vehicular environment of the component.
Claim 3
Dependent Claim
55 words
A component as defined in claim 1 wherein said clear material includes fine metallizing particles generally evenly distributed in the coating, the amount of said particles being such that the color of the substrate is presented as the color appearance of the component with the particles imparting a three-dimensional metallized enhancement to the color appearance.
Claim 4
Dependent Claim
14 words
