Abstract

PURPOSE: To extend the pot life of paint, by using the binder blending the surface active agent of phosphate ester type to the hardened system binder blending specific active agent to form magnetic paint.
CONSTITUTION: To the hardened system binder including R-C00H.M (where: M is amine and R is alkyl) type surface active agent [e.g., C11H23-COOH (C4H9)3N], 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 blended to form the magnetic paint by taking this as a binder. The said magnetic paint has long pot life and excellent magnetic recording excellent in the electromagnetic performance body can be formed by coating it on the base.
