| 摘要 |
Textile materials and foils are dyed or printed by treatment with an aqueous preparation containing (a) the reaction product of diketene with a polyalkylene glycol (or oxide)-modified polyvinyl alcohol, (b) a stabilized diazosium compound and optionally (c) an aminoplast precondensate of which the methylol radicals may be partly or fully etherified; and the colorations or prints fixed by heating to 90 DEG C or above. Suitable materials are fabrics, knitted fabrics and fibre fleeces made from natural, regenerated or acetylated cellulose, wool, silk, polyamides, polyesters, polyacrylonitriles, polyvinyl chloride, glass fibres or asbestos, as well as foils based on cellulose or synthetic materials, paper and cardboard.
