Abstract

PURPOSE: To extend the pot life of paint, by using the binder blending the hardened system binder blended with specific surface active agent for the surface active agent of phosphate ester type to form the magnetic paint.
CONSTITUTION: To the hardened system binder including the sorbitanester type surface active agent (e.g., sorgen 40, made by Daiichi Kogyosha), mono, di, tri phosphate ester (alcohol phosphate ester type surface active agent) represented in equations I, II, III (where: R is alkyl, alkylphenyl and n is 0 or more) is also blended and the magnetic paint is formed by taking this as a binder. The said magnetic paint is longer in the pot life, and the effect of head attachment prevention with sorbitanester can sufficiently be kept longer, and the magnetic recording substance excellent in electromagnetic performance can be formed by coating it on the base.
