Abstract: The colored copolymer microspheres with negative charge and high dye content were prepared by dyeing poly (styrene-butyl acrylate-vinylbenzyl trimethylammonium chloride) microspheres with reactive red 24.The morphology,particle size and zeta potential of microspheres were characterized.The effects of their applications in cotton fabrics pigment printing were studied.The results indicated that the microspheres were uniformly spherical.After dyeing,the particle size increased from 63nm to 85nm,the zeta potential decreased from +56.9mV to -28.9mV,and the dye content was 561mg/g.When the microsphere amount in paste was increased from 0.1% to 0.3%,the brightness of prints decreased from 67.4 to 58.0.The fabric had better color saturation when there was no binder in paste.The prints had favorable rubbing and washing color fastness,which were more than 4 grades.
