Abstract
Toners comprised of a mixture of a cyan toner, a magenta toner, a yellow toner, and an optional black toner, each of said toners being comprised of resin and pigment, and wherein the pigment for the cyan toner is a .beta. type copper phthalocyanine, the pigment for the magenta toner is a quinacridone, the pigment for the yellow toner is a diazo benzidine, and the pigment for the black toner is carbon black.

Toners comprised of a mixture of a cyan toner, a magenta toner, a yellow toner, and an optional black toner, each of said toners being comprised of resin and pigment, and wherein the pigment for the cyan toner is a .beta. type copper phthalocyanine, the pigment for the magenta toner is a quinacridone, the pigment for the yellow toner is a diazo benzidine, and the pigment for the black toner is carbon black, and wherein each of said cyan, magenta, and yellow pigments are dispersed by flushing said cyan, magenta or yellow pigment into said toner resin, wherein a cyan, magenta or yellow pigment water wet cake is mixed with toner resin and the water is removed to generate pigmented resin.
A combination of four color toners comprised of a cyan toner, a magenta toner, a yellow toner, and a black toner, each of said toners being comprised of resin and pigment, and wherein the pigment for the cyan toner is a .beta. type copper phthalocyanine, the pigment for the magenta toner is a quinacridone, the pigment for the yellow toner is a diazo benzidine, and the pigment for the black toner is carbon black, and wherein each of said cyan, magenta, and yellow pigments are dispersed by flushing said cyan, magenta or yellow pigment into said toner resin, wherein a cyan, magenta or yellow pigment water wet cake is mixed with toner resin and the water is removed to generated pigmented resin;
- and wherein each of the resulting pigmented resin concentrate product is mixed and diluted with additional toner resin to generate cyan, magenta and yellow toners containing each of said magenta, cyan or yellow pigment, respectively.
Toners comprised of a cyan toner, a magenta toner, a yellow toner, and an optional black toner, each of said toners being comprised of resin and pigment;
- and wherein the pigment for the cyan toner is a .beta. or beta type copper phthalocyanine, the pigment for the magenta toner is a xanthene silicomolybdic acid salt of Rhodamine 6G basic dye, the pigment for the yellow toner is a diazo benzidine, and the pigment for the black toner is carbon black, and wherein said cyan pigment, said magenta pigment, and said yellow pigment are prepared by a flushing process, and which process comprised of mixing a wet cake of said magenta pigment, a wet cake of said yellow pigment, and a wet cake of said cyan pigment with said resin, thereafter heating to remove water, and wherein each of the resulting pigmented resin concentrate products is mixed and diluted with additional toner resin to generate cyan, magenta and yellow toners.
