Multi-layer dry paint decorative laminate having discoloration prevention barrier

A multi-layer decorative laminate for applying a layer of color to a substrate surface, the laminate comprising:

• a flexible decorative dry paint layer comprising a color layer which includes a resinous binder and a pigment;
• a pressure-sensitive adhesive layer overlying the decorative dry paint layer;
• and
• a flexible barrier coat between the adhesive layer and the color layer, the barrier coat made from an emulsion of ethylene-vinyl alcohol copolymer and a migratory polymeric material in dry film form to provide a barrier layer as a stable emulsion with an internal boundary layer formed by the migratory polymeric material, the barrier layer and its internal boundary layer effective to inhibit migration of discoloration-causing azo-type pigments from a painted surface of the substrate through the adhesive layer to the color layer sufficiently to essentially prevent migrating pigments from a painted surface of the substrate from causing noticeable color change in the color layer under room temperature conditions, said barrier layer having a thickness of less than about 0.25 mils.

A multi-layer decorative wall film for applying a layer of color to a substrate surface, the wall film comprising:

• a flexible decorative dry paint layer comprising a color layer which includes a resinous binder and a pigment;
• a pressure-sensitive adhesive layer overlying a surface of the dry paint layer and adapted for adhering the wall film to a substrate surface;
• a release liner overlying a surface of the dry paint layer opposite from the adhesive layer, the release liner removable from the dry paint layer for exposing an outer surface of the decorative dry paint layer when the pressure-sensitive adhesive layer adheres the wall film to the substrate surface and the release liner is peeled away from the decorative dry paint layer;
• and
• a thin, flexible barrier layer disposed between the adhesive layer and the color layer, the barrier layer made from an ethylene-vinyl alcohol material that in dry film form inhibits migration of discoloration-causing pigments from a painted surface of the substrate through the adhesive layer to the color layer sufficiently to retard noticeable color change, caused by such pigments, from occurring in the color layer under room temperature conditions, said barrier layer having a thickness of less than about 0.25 mils.

• a thin, flexible barrier layer disposed between the adhesive layer and the color layer, the barrier layer made from an ethylene-vinyl alcohol material that in dry film form inhibits migration of discoloration-causing azo-type pigments from a painted surface of the substrate through the adhesive layer to the color layer, in which the barrier layer produces a color shift of less than about 0.4 Δb* C.I.E. color units at 60° C. for 400 hours, said barrier layer having a thickness of less than about 0.25 mils.

A multi-layer decorative wall film for applying a layer of color to a substrate surface, the wall film comprising:

• a flexible decorative dry paint layer comprising a color layer which includes a resinous binder and a pigment;
• a decorative pressure-sensitive adhesive layer overlying a surface of the dry paint layer and adapted for adhering the wall film to a substrate surface;
• and
• a thin, flexible barrier layer disposed between the adhesive layer and the color layer, the barrier layer comprising an emulsion of ethylene-vinyl alcohol copolymer and a dispersed urethane material in either a thermoplastic or crosslinked dry film form that reduces migration of discoloration-causing pigments from a painted surface of the substrate through the adhesive layer to the color layer, said barrier layer having a thickness of less than about 0.25 mils.
