ABSTRACT:
A method for preparing polyvinyl chloride sheets for membrane press forming which comprises contact bonding of a preheated first polyvinyl chloride sheet on the heating drum, contact bonding of at least one other layer of preheated polyvinyl chloride sheet thereon, contact bonding of a transfer film thereon and embossing by emboss-roll thereon, wherein said transfer film has a laminated structure comprising a polyester film, a release coat layer, a resin coat layer and a hot melt coat layer successively from the surface layer. The method of the present invention provides a sheet for membrane press forming which has excellent stain and scratch resistance. Furthermore, after this sheets is subjected to overlay-laminate forming on materials such as plywood and the like, splendid forms can be obtained without surface cracks caused by expansion.
