Method for producing polyester resin particle dispersion material, method for producing polyester resin particles, and method for producing electrophotographic spherical toner |
摘要 |
<p>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.</p> |
