1. 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.
