MORDANTING PROCESS FOR COLOR PRINTING MATERIALS

A mordanting process for color printing materials which comprises using a dispersion of fine coacervate particles prepared by reacting a polymer having a cationic nitrogen-containing group which acts as a mordant for a dye having an anionic group and diffusible in an aqueous medium and a phthalic ac...

Beschreibung
Zusammenfassung:	A mordanting process for color printing materials which comprises using a dispersion of fine coacervate particles prepared by reacting a polymer having a cationic nitrogen-containing group which acts as a mordant for a dye having an anionic group and diffusible in an aqueous medium and a phthalic acid derivative of gelatin, polyvinyl alcohol or starch in an aqueous binder. Examples of said polymer having the nitrogen-containing group are poly-2-vinyl pyridine, methyl p-toluenesulfonate of poly-4-vinyl pyridine, poly-4-vinylbenzyl-trimethyl ammonium chloride, poly-4-vinylbenzyl-triethanol ammonium chloride, benzyl chloride of polymethacrylic acid dimethylamino ethanol ester, acetate of partially amino guanidized polyvinyl methyl ketone, and aminoguanidized dialdehyde starch.
