Abstract

PURPOSE: To give the lubricity on the surface of the parting layer and to give excellent parting property and wear-proof performance, by commonly using the cellulosic resin and silicone resin to the parting layer provided on the substrate.
CONSTITUTION: On the substrate 1 such as polyester, acetate and peeling paper, the cellulosic resin such as nitrocellulose and the silicone resin having molecular weigth of 5,000W100,000 are dissolved into a suitable solvent and this paint is coated with dried thickness of 0.5W2μ to form the parting layer 2. The magnetic substance layer 3 is formed by painting the magnetic powder with the binder on this parting layer 2. The layer 2 of this magnetic sheet is excellent in foil cut and the adherence of the magnetic layer 3 to the mirror polish finish plate is not caused.
