DISPERSE DYESTUFF COMPOSITIONS |
摘要 |
Aqueous concentrates or printing pastes of disperse dyes or disperse optical brighteners contain a dispersing agent which is the product of reacting formaldehyde with one or more mono or di-(C1-12)alkyl substituted phenols optionally together with one or more N-(C12-22)alkyl alkylene polyamines and alkoxylating the condensation product with 30-450 moles of lower alkylene oxide. The compositions give dyeings and printings with excellent colour yield. |
