Abstract
PURPOSE: To lower the rate of reaction of the thermosetting resin base binder and improve its pot life by adding nitrocellulose to a vinyl choloride-vinyl acetate copolymer-polyurethane system.
CONSTITUTION: The binder composed of polymerizable polyurethane resin and vinyl chloride-vinyl acetate copolymer being compatible is added with nitrocellulose of 5 to 50wt% thereof. This binder is kneaded with magnetic powder in a solvent. The resultant magnetic coating is coated on a polyester base. After surface finishing, it is heat-set.
