PURPOSE:To increase the adhesive strength between a paper base material and a magnetic layer, by using a material containing mainly a styrene-acrylic ester copolymer for an adhesive layer which is used to form the magnetic layer on the paper base material. CONSTITUTION:A transferable magnetic sheet containing an adhesive layer composed mainly of a styrene-acrylic ester copolymer (wt. ratio of stylene to acrylic ester is preferably 7/3-3/7) is pressed with heat onto a paper base material for transfer. Otherwise a transferable magnetic sheet containing a base film, a mold releasing layer and a magnetic layer is provided on the above-mentioned adhesive layer and pressed with heat onto the paper base material, or otherwise the said adhesive layer is formed on the paper base material, and the magnetic layer is formed on the adhesive layer without using the transfer method. Thus a magnetic recording medium like a magnetic card, etc. is obtained. |
