Resin particles and process for producing the same

摘要

Subjects of the present invention are to provide resin particles having high ability and suitable for various purposes and to provide preparation method thereof.This invention provides resin particles each of which is formed by two curved surfaces or by one curved surface and one plane surface, has a boundary line between these two surfaces and satisfies the relationships:wherein D is particle diameter in horizontal direction and d is the maximum height in longitudinal direction in a side view in which the boundary line is placed in horizontal direction.
