Abstract

PURPOSE: To secure both an excellent square ratio and the maximum residual magnetic flux density, by using a new binder component.
CONSTITUTION: The binder is composed mainly of the copolymer composed of the 70W95% (weight) vinyl chloride, 1W25% hydroxyethyl acrylate or hydroxyethyl methacrylate and 0W10% acryic acid or methacrylic acid along with the polyisocyanate added when necessary as the hardening agent component. The ferromagnetic powder is stuck to the supporter via the binder mentioned above. In such way, the magnetic properties can be obtained with about 0.80W0.84 square ratio and about 1,210W1,400 gauss of the maximum residual magnetic flux density each.
