Abstract

PURPOSE:To form a colored magnetic sheet having a colored layer whose adhesiveness is satisfactory, and also a distinct color tone, by providing a concealed layer containing nonmagnetic metallic powder, between a magnetic layer and a colored layer. CONSTITUTION:A concealed layer is formed by use of a coating material consisting of about 30-80wt% metallic powder such as aluminum, silver, zinc, thin, etc., and about 70-20wt% a binder (example: vinyl chloride-vinyl acetate resin, butyral resin, etc.). That is to say, a magnetic layer 2 is provided on the base body 1 of polyester, etc. by applying the magnetic powder together with a binder, a concealed layer 3 of about 3mum thickness is formed on said layer by use of said coating material, and after that, moreover a color paint which has mixed a color pigment and a binder is applied on said layer, a colored layer is formed, and it is made a colored magnetic sheet. Said sheet is used by providing an adhesive agent layer 5 on the lower surface side of the base body 1, and thermally sticking to a base material such as vinyl sheet, cloth paper, etc. through said layer.
