Abstract
A toner comprised of pigment, and an addition polymer resin generated from about 55 to about 80 weight percent of styrene, from about 1 to about 25 weight percent of acrylate, from about 1 to about 20 weight percent of acrylonitrile, and from about 0.5 to about 5 weight percent of acrylic acid.
Claims18
A toner consisting essentially of pigment, and an addition polymer resin generated from about 55 to about 80 weight percent of styrene, from about 1 to about 25 weight percent of acrylate, from about 1 to about 20 weight percent of acrylonitrile, and from about 0.5 to about 2 weight percent of acrylic acid.
A toner consisting essentially of pigment, and an emulsion of a styrene-acrylate-acrylonitrile-acrylic acid resin obtained from the polymerization of from about 55 to about 80 weight percent of styrene, from about 5 to about 25 weight percent of acrylate, from about 1 to about 20 weight percent of acrylonitrile, and from about 0.5 to about 5 weight percent of acrylic acid, and wherein said resin possesses a weight average molecular weight (M.sub.w) of from about 18,000 to about 35,000 and a number average molecular weight (M.sub.n) of from about 5,000 to about 10,000, relative to styrene standards.
A developer comprised of a toner comprised of pigment, and an addition polymer resin generated from about 55 to about 80 weight percent of styrene, from about 1 to about 25 weight percent of acrylate, from about 1 to about 20 weight percent of acrylonitrile, and from about 0.5 to about 5 weight percent of acrylic acid, and carrier.
A toner consisting essentially of colorant, and an addition polymer resin generated from about 55 to about 80 weight percent of styrene, from about 1 to about 25 weight percent of acrylate, from about 1 to about 20 weight percent of acrylonitrile, and from about 0.5 to about 5 weight percent of acrylic acid.
