Method of producing scale-like composite particles
First Claim
1. A method of producing scale-like composite particles, comprising the steps of:
- preparing a dispersion liquid including scale-like inorganic particles coated with resin and spherical fine particles having an average particle diameter in a range from 0.1 to 3.0 μ
m, said scale-like inorganic particles coated with the resin and the spherical fine particles being dispersed in water, alcohol, or a mixture thereof, andspraying the dispersion liquid in a heated air stream for drying so that the spherical fine particles are adhered on the scale-like inorganic particles coated with resin by a static electricity generated by contact between the particles.

Abstract
In a method of producing scale-like composite particles, a dispersion liquid is prepared to include scale-like inorganic particles coated with resin and spherical fine particles having an average particle diameter in a range from 0.1 to 3.0 μm. The scale-like inorganic particles coated with the resin and the spherical fine particles is dispersed in water, alcohol, or a mixture dispersant of the water and the alcohol. Then, the dispersion liquid is sprayed in a heated air stream for drying so that the spherical fine particles are adhered on the scale-like inorganic particles coated with resin by an electrostatic force generated by contact between the particles.
