Abstract
PURPOSE: To improve magnetic characteristics while increasing the strength of adhesion to the base of magnetic layer, by forming, on the base, a copolymerized polyester resin layer containing a metallic sulfonate group, as a substratum and by providing a magnetic layer onto this layer.
CONSTITUTION: On a base, a substratum consisted of copolymerized polyester resin containing a metallic sulfonate group obtained by copolymerizing a component, containing the metallic sulfonate group such as 5-sodium sulfoisophthalate, 5- potassium sulfoisophthalate, 2-sodium sulfoterephtalate, and 2-potassium sulfoterephtalate or the like into polyester resin, is formed in 0.05W0.3μm dry thickness and, a magnetic layer is provided onto it.
