Abstract

PURPOSE: An emulsion coating is made from a binder containing more than a specific amount of nitrated cotton, an inorganic pigment, an organic solvent and water, then the coating is applied to the base surface and dried to form the titled coating film suitable for magnetic cards or other purposes, because of its high wearing resistance.
CONSTITUTION: A binder containing more than 30% of nitrated cotton, an inorganic pigment, preferably synthetic calcium carbonate treated with a silane, of 1W3 micron major axis, an organic solvent such as a ketone or ester, preferably boiling at a temperature equal to or lower than water, and water (more than 20% based on the liquid components) are used to prepare an emulsion coating. Then, the coating is applied to a base for magnetic recorder such as magnetic card on the surface. Then, the coating is forcibly dried.
