摘要： The invention relates to the fixing of disperse dyestuffs which are printed by transfer from support webs onto fabric webs. Fabrics which are cellulosic or part cellulosic are treated with suitable resins which are uncured or part cured and are chosen to have hydroxymethyl, alkoxymethyl and/or aldehyde groups capable of reacting with corresponding reactive amino, hydroxy and/or hydroxyalkylamino groups of the dye or dyes used in the printing inks. The heat treatment for transfer of the print from the support to the textile fabric is effected under such conditions of temperature and time that either curing or end curing of the resins takes place with simultaneous fixing of the dyes onto the textile fabric through reaction between the reactive groups of the dyes and corresponding unreacted end groups of the resins.
