摘要： 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.
