AQUEOUS DISPERSION CONTAINING COLORED FINE PARTICLE

摘要

PURPOSE: To obtain a colored fine particle aqueous dispersion containing fine particles mainly comprising a colored and cross-linked polyester resin and fine particles comprising a thermoplastic resin component and realizing high recording dignity and not generating clogging, etc., according to sedimentation of particles and a dried film formation. CONSTITUTION: The objective dispersion contains (A) 5-40wt.% fine particles mainly comprising a cross-linked polyester resin colored with a dye or a pigment containing 20-2000eq./ton ionic group preferably composed of an organic amine salt of carboxylic acid group and (B) 1-40wt.% fine particles comprising a thermoplastic resin composed of a (co)polymer preferably including >=50wt.% ethylene and/or propylene and having >=35 deg.C softening temperature. The component B is not swollen in a lower alcohol, an alkylene glycol and an alkanolamine.
