Document Type and Number:
Japanese Patent JPH04304240
Kind Code:
A
Abstract:
PURPOSE:To produce a marking film by the calendering method which enables fine adjustment of hardness which is impossible when a polyurethane/vinyl chloride copolymer resin is used alone as a resin based. CONSTITUTION:A process for producing a marking a film having a Shore hardness in the range of 70-90 from a polyurethane/vinyl chloride copolymer resin as a main resin base, which comprises calendering a resin composition prepared by mixing 70-90wt.% above copolymer resin with 30-1wt.% ethylene/vinyl chloride copolymer resin having an ethylene content of 2-12wt.% and an average degree of polymerization of 400-1050.
