Abstract: A SYSTEM FOR SEMI-PERMANENTLY DYEING HUMAN HAIR BY PLATING OUT A WATER INSOLUBLE PHTHALOCYANINE DYESTUFF ONTO A CATIONIC LAYER ENSHEATHING HAIR STRANDS AND ACTING AS A DYE COUPLER FOR THE DYESTUFF. THE CATIONIC LAYER IS APPLIED TO THE HAIR STRANDS FROM AN AQUEOUS MEDIUM IN WHICH THE CATIONIC MATERIAL AND WATER INSOLUBLE PHTHALOCYANINE DYESTUFF CONSTITUTE A SINGLE COMPOSITE MIXTURE WITH THE CATIONIC COMPOUND AS AN INGREDIENT IN INTIMATE CONTACT WITH THE DYESTUFF AND ACTING AS A DISPERSANT SO AS TO OBTAIN UNIFORM DISTRIBUTION OF THE DYESTUFF IN THE AQUEOUS MEDIUM AND LEVELING OF THE DYESTUFF AS A WATERFAST DYE ON THE HAIR SUBSTRATE.
