N-ALKYLPHTHALIMIDE MIXTURES FOR USE AS CARRIERS IN DYEING AND OPTICAL BRIGHTENING

摘要

A highly emulsifiable mixture of N-alkylphthalimides consists essentially of: (a) N-(n-propyl)-phthalimide (b) N-(sec.-C4-6-alkyl)-phthalimide and (c) N-(n-C4-6-alkyl)-phthalimide wherein the weight ratio (a)/(P) is in the range of 3/100 to 14/100. They may be used as carriers for the dyeing of fibrous material.
