Abstract
PURPOSE: A magnetic paint composition with enhanced adhesion to a substrate, lowering friction coefficient of a magnetic face, which is obtd. by compounding as a binder a specified amt. of nitrocellulose contg. an org. solvent inert to an isocyanate with a magnetic paint for a magnetic recording medium.
CONSTITUTION: At least 20wt% org. solvent dissolving nitrocellulose and inert to an isocyanate group, such as ethyl acetate or methyl ethyl ketone, or a mixt. consisting of said org. solvent and an org. solvent not dissolving nitrocellulose and inert to the isocyanate group, such as hexane or toluene, is incorporated in nitrocellulose. Then 0W50wt%, calculated on pure nitrocellulose, said nitrocellulose contg. the org. solvent and essentially contg. no water, alcohol, etc., is added as a binder to a paint composition for a magnetic recording medium consisting of a magnetic powder, a dispersant, etc., to prepare the purpose magnetic paint composition.
