ABSTRACT:
A patterned decorative material is prepared by a method which comprises application of a thermosetting powder coating material to a base plate; melting of the thermosetting powder coating material by heating; embossing of the coating layer alone while the melt thermosetting powder coating material has a gel fraction formed by a hardening reaction of 15 to 75 weight percent; and further heating to form a hardened coating on the base plate. The prepared patterned decorative material is excellent in appearance, corrosion resistance, weathering resistance and abrasion resistance and free from the defects of conventional steel plates coated with polyvinyl chloride and the like, such as formation of craze and loss of luster.
