Abstract
In-situ polymerized polymer film facilitates improved paint film appliques with reduced defects. The paint film appliques comprise the in-situ polymerized polymer film as a carrier layer and at least one color layer assembled as a laminate, optionally further comprising at least one topcoat layer on one major surface of the laminate and an adhesive layer on the other major surface of the laminate.
Claims30
A method of forming a paint film applique, the method comprising steps of:
- forming an in-situ polymerized color layer from a polymerizable composition for the color layer, wherein the color layer is a reactive polymer film;
- forming an in-situ polymerized carrier layer from a polymerizable composition for the carrier layer, wherein the carrier layer is in-situ polymerized on the color layer and covalent bonds form with the color layer at an interface between the color layer and the carrier layer;
- optionally, forming a topcoat layer;
- and
- optionally, forming an adhesive layer opposite the topcoat layer,
- wherein at least the in-situ polymerized carrier layer and the in-situ polymerized color layer are formed by co-extrusion of the polymerizable compositions to simultaneously form the at least two layers.
