Fluorocarbon resin content marking film

摘要

PURPOSE: To obtain a marking film excellent in long-term durability, adhesion to adherend, corrosion resistance and weather resistance by applying a pressure- sensitive adhesive to at least either surface of a specified fluororesin-containing film. ;CONSTITUTION: The marking film is prepared by applying a pressure-sensitive adhesive (e.g. acrylic pressure-sensitive adhesive) to at least either surface of a fluororesin-containing film prepared by adding 0.1-20 pts.wt. amorphous SiO₂, to 100 pts.wt. vinylidene fluoride resin comprising the two layers including an upper layer desirably containing 80-50 pts.wt. vinylidne fluoride resin and 20-50 pts.wt. methacrylic ester resin and a lower layer containing 20-50 pts.wt. vinylidene fluoride resin and 80-50 pts.wt. methacrylic ester.;COPYRIGHT: (C)1995,JPO
