    摘要： A polyester resin particle dispersion material, in which the average particle size can be easily controlled within a broad range and is less likely to form irregular particles, and which is also suited for use in adhesives, is produced by dispersing a resin melt containing, as an essential component, a polyester resin (A) having a terminal structure in which an alkyl group having 4 to 20 carbon atoms or an alkenyl group having 4 to 20 carbon atoms is bonded to a carbon atom to which a carboxyl group is attached, or a carbon atom adjacent to this carbon atom, a portion or all of carboxyl groups in the polyester resin (A) being neutralized with a basic compound, in a heated aqueous medium in a melted state, and cooling the dispersed resin melt.

    摘要： A novel manufacturing method for toner used in electrophotography employing no organic solvent is disclosed. The method comprises the steps of: (1) combing a colored melted resin (a) and an aqueous medium (b), wherein the colored melted resin (a) is prepared by heating and melting a kneaded material containing a synthetic resin for use in an electrophotographic toner having an ionic group and a coloring pigment, and the aqueous medium (b) contains a substance capable of neutralizing the ionic group, and possesses a raised temperature not lower than the softening point of the synthetic resin by way of heating with application of pressure where necessary; (2) dispersing the colored melted resin (a) in the aqueous medium (b) by mechanical means while maintaining a mixture of the colored melted resin (a) and the aqueous medium (b) at a temperature not lower than the softening point of the synthetic resin; (3) producing an aqueous suspension of colored resin microparticles by means of sudden cooling; (4) separating the colored resin microparticles from the suspension; and (5) drying the separated colored resin microparticles.

    摘要： A toner containing at least a colorant and a resin, in which the resin is a polyester resin having a total acid radical content of 2 to 50 mg equivalents per 100 g and having a weight-average molecular weight of 2,000 to 100,000, and the toner particles are spherical and have an average particle diameter of 3 to 13 .mu.m. The toner is produced by a process comprising adding an aqueous medium to a dispersion of at least a colorant and an anionic self-emulsifiable resin in a water-miscible organic solvent to cause phase inversion to obtain an emulsion, and separating the produced particles from the aqueous medium, followed by drying, in which the anion self-emulsifiable resin is a polyester resin having a neutral salt structure, having a total acid radical content of 2 to 50 mg equivalents per 100 g and having a weight-average molecular weight of 2,000 to 100,000.
