Abstract

PURPOSE: To increase the heat-resistance, anti-chemicals and hardwearing properties each by providing the colored layer, in which the pigment is scattered via the binder of the polyisocyanate of low molecular amount as well as the copolymer of vinyl chloride - vinyl acetate - vinyl alcohol, on the surface of the magnetic layer of the magnetic card or the like.
CONSTITUTION: Such binder is used for colored layer 3 on base film 1 as the mixture of two monomers of the vinyl chloride and vinyl acetate with the composition ratio of 98W70:2W30, the polyvinyl alcohol of composition ratio of 98W70:2W30 to form the ternary copolymer to the above monomers plus the polyisocyanate of the low molecular amount featuring the branched isocyanate group with 2W20wt% mixture to the copolymer provided at the areas excepting the both terminals each. Such pigment is used by 10W80wt% to the binder. For the binder of magnetic layer 2, the copolymer of vinyl chloride - vinyl acetate - vinyl alcohol is used as sell. Then heat-sensitive adhesive layer 4 is formed to the lower surface of film 1 and then adhered to cross paper 5 or the like in order to obtain the colored magnetic card.
