PASTE COMPOSITION FOR PRINTING ON CELLULOSE-CONTAINING MATERIALS WITH VAT DYES Russian patent published in 2003 - IPC

FIELD: textile industry. SUBSTANCE: composition contains vat dye, sulfuric acid reducing agent, alkali agent, antioxidant, and thickening, said antioxidant being surfactant based on triethanolamine salt of alkylphenolpolyglycol sulfonic acid ester, surfactant based on alkylpolyoxyethylene glycol ether-acetaldehyde etherification product obtained in presence of butanol, and biological preparation containing oxidoreductases producing effect on hydroperoxide compounds and/or exo-activity amylases. Invention allows obtaining stable coloration in visible and IR spectrum regions with deviations in intensity index no more than 1.025 times and remission index no more than 5%, which is within technologically permissible limits. In addition, significant depolymerization of cellulose fiber capable of leading to losses in mechanical strength of textile is prevented. EFFECT: improved quality of coloration and eliminated damage of support material. 1 tbl, 5 ex
