Abstract
Abstract A print paste for printing textiles of polyester, cellulose acetate, cellulose triacetate and mixtures of the same with other fibers which is based on a disperse dye, thickener, ethanolamide of a carboxylic acid and water and which is characterized by a content of at least one phenol which has been oxyethylated twice to six times. The paste yields prints having excellent color strength and levelness.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
A print paste for textile material consisting essentially of a polyester, cellulose acetate, cellulose triacetate and mixtures of the same which contains, in 1000 parts by weight of paste: a. from 20 to 80 parts by weight of a disperse dye; b. from 3 to 10 parts by weight of a twofold to sixfold oxyethylated phenol selected from the group consisting of mononuclear and binuclear phenols and bisphenols having a molecular weight of up to 250; c. from 5 to 30 parts by weight of an ethanolamide of a carboxylic acid of twelve to twenty-four carbon atoms; d. from 500 to 800 parts by weight of a thickening agent; and e. water to make up the paste to 1,000 parts by weight.
Claim 2
