ABSTRACT:
A powdery single-layer film laminate having excellent scratch resistance and stain resistance is produced. The powdery single-layer film laminate comprises a substrate, a binder layer and a powdery single-layer film composed of a large number of powdery particles embedded in a single-layer in a partially protruded state on the surface of said binder layer, and said binder layer has Tg of at least 60° C. or has substantially no Tg. An example of the method of producing it comprises applying a coating liquid of a polymer resin in an organic solvent to a substrate and drying to form a coating layer in which the organic solvent partially remains, attaching powdery particles to and embedding in the surface of the formed coating layer, and removing the excess powder attaching to the surface of the coating layer and removing the residual organic solvent.
