Abstract: A METHOD OF DYEING, PRINTING OR OTHERWISE COLORING ACRYLONITRILE POLYMERS OR POLYVINYLIDENE DICYANIDES IN WHICH THERE IS ADDED THE POLYMER TO BE COLORED A BASIC DYE CONTAINING A FLAVYLIUM CATION. THE BASIC DYE CAN BE INCORPORATED DIRECTLY INTO A SOLUTION OF THE POLYMER OR CAN BE APPLIED TO THE POLYMER UNDER CONVENTIONAL CONDITIONS FOR DYEING OR PRINTING TEXTILE MATERIALS WITH BASIC DYES.
