を著しくそこなうので好ましくない。The other base material to be laminated with the soft vinyl chloride sheet in the present invention is a biaxially oriented polyester film, which is a biaxially oriented film of commonly used polyester such as unsaturated polyester resin, alkyd resin, and polyethylene terephthalate. Ru. As this biaxially stretched polyester film, one with a thickness of 5 to 100 μm can be used, but from the viewpoint of ease of handling and processing,
Preferably, the thickness is μm. If the thickness is less than 5 μm, wrinkles are more likely to occur during thermal welding, making it difficult to use.
If it exceeds 00 μm, the laminated sheet becomes too hard, which significantly impairs its marketability, which is not preferable.

ム表面を該′溶剤でふく程度で十分実用的である。The present invention is characterized in that a laminated layer of a soft vinyl chloride sheet and a biaxially oriented polyester film is thermally welded, and at that time, the surface of the polyester film is treated with an organic solvent or corona discharge. becomes possible. Examples of organic solvents that can be used include aromatic solvents such as benzene, toluene, and xylene, ketone solvents such as acetone and methyl ethyl ketone, and tetrahedral O7. Although the reason is not clear, alcohols such as methyl alcohol and ethyl alcohol, 1T, are not preferable because they do not have a thermal welding effect. As a treatment method, wiping the surface of the film with the solvent is sufficient and practical.
