A decorative dry paint wall film includes a layer of dry paint, a pressure-sensitive adhesive layer on one side of the dry paint layer, and a release liner in releasable contact with the dry paint layer on a side opposite from the pressure-sensitive adhesive (PSA). The release liner has a matte release coat layer that contacts the dry paint layer. The release liner is released from the dry paint layer after the PSA side is attached to a wall. The matte release coat transfers a matte finish to the dry paint layer when the release liner is removed. The wall film includes a barrier layer to protect against significant discoloration of the color in the dry paint layer caused by migration of azo-type pigments from a painted wall surface. The barrier layer in one embodiment comprises a dry emulsion containing ethylene-vinyl alcohol and a dispersed polymeric material which in one embodiment comprises a urethane material.

What is claimed is: 1. 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 a surface of the decorative dry paint layer and adapted for adhering the laminate to a substrate surface; and a thin, flexible barrier layer disposed between the adhesive layer and the color layer, the barrier layer comprising an ethylene vinyl alcohol material forming a dry film form emulsion that retards 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. 2. The decorative laminate according to claim 1 in which the barrier layer produces a color shift of less than about 0.40 Δb* C.I.E. color units at 60° C. for 400 hours. 3. The decorative laminate according to claim 1 in which the barrier layer retards degradation of the adhesive layer caused by constituents migrating from the color layer toward the adhesive layer. 4. The decorative laminate according to claim 1 in which the barrier layer has a glass transition temperature (Tg) greater than about 50° C. 5. The decorative laminate according to claim 1 in which the barrier layer material inhibits migration of azo-type discoloration-causing pigments. 6. The decorative laminate according to claim 1 in which the barrier layer comprises an emulsion containing ethylene-vinyl alcohol blended with a dispersed polymeric material. 7. The decorative laminate according to claim 6 in which the dispersed polymeric material comprises a urethane material. 8. The decorative laminate according to claim 6 in which the barrier layer contacts both the pressure-sensitive adhesive layer and the color layer in the absence of separate adhesive tie layers. 9. The decorative laminate according to claim 6 in which the ethylene vinyl alcohol component is thermoplastic or crosslinked. 10. The decorative laminate according to claim 6 in which the dispersed polymeric material migrates to form a boundary layer on a side of the barrier layer. 11. 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. 12. The decorative laminate according to claim 11 in which the migratory polymeric material comprises a urethane material. 13. The decorative laminate according to claim 11 in which the barrier layer emulsion is a thermoplastic or crosslinked material. 14.
