PROCEDIMIENTO PARA LA ESTAMPACION RESISTIVA O DE DESCARGA DEMATERIALES TEXTILES SINTETICOS

摘要

A "wet-on-wet" process for the resist or discharge printing of synthetic textile materials using alkali-dischargeable disperse dyestuffs which are free from sulphonic acid and carboxylic acid groups, and free from carboxylic acid ester groups which if hydrolysed would leave carboxylic acid groups attached to the dyestuff molecule, and using sodium or potassium silicate as the alkali. The prints have much better definition than when conventional alkalies are used.
