摘要： PURPOSE:The titled composition forming a film improved in the resistance to water, boiling water, and alkali, prepared by emulsion-polymerizing a polymerizable monomer having conjugated unsaturated bonds and containing a polymerizable dibasic acid in the presence of an anionic surfactant and colloidal silica. CONSTITUTION:A polymerizable monomer having conjugated unsaturated bonds and containing 0.1-1wt% polymerizable dibasic acid is emulsion-polymerized in the presence of 0.1-1wt%, based on the total monomer, anionic surfactant and 0.1-4wt%, in terms of solids, colloidal silica. When the amount of the polymerizable dibasic acid used is below 0.1wt%, based on the total monomer, the object can be not be attained, while when it is above 1wt%, no improvement in the resistance to water and alkali can be obtained. When the amount of the surfactant used is below 0.1wt%, the dispersion becomes unstable, while when it exceeds 1wt%, the water resistance, etc., of the formed resin are adversely affected, which are not desirable.

The magnetic distortion of the amorphous soft magnetic metal foils 1 are to be less than approximately 5 ppm, and the volume resistance ratio is to be more than approximately 100 uΩ.cm. Insulating resin layers 2, 3 are formed on both sides of the amorphous soft magnetic metal foils 1 to make a film. The film is properly cut to meet the size of E-type core 4 which is a part of magnetic core constituting a coil or a transformer. Then, the film is adhered on an end 6 of the E-type core 4. As a result, electromagnetic characteristics such as Q-factor of the coil or the transformer, and the effective permeability can be improved drastically and leakage of an electro-magnetic field can be restrained.
