Abstract
An aqueous solution of a chromophore having at least one sulfonic acid or carboxylic acid functionality and a triethanolamine ethoxylate is provided for a fugitive colorant useful in ink formulations or to temporarily tint textile fibers. Preferably the triethanolamine ethoxylate contains at least nine moles of --CH.sub.2 CH.sub.2 O-- units and is present in a molar excess per acid functionality of the chromophore.
Claims30
A fugitive colorant solution comprising a chromophore, having at least one sulfonic acid or carboxylic acid functionality, in an amount sufficient to provide coloration of said solution and at least one molar equivalent of triethanolamine ethoxylate per acid functionality of said chromophore, said triethanolamine ethoxylate having greater than 25 moles of --CH.sub.2 CH.sub.2 O-- units.
A fugitive colorant solution comprising from 1 to 40 weight percent of a chromophore having at least one sulfonic acid or carboxylic acid functionality, wherein said chromophore is selected from azo, triphenylmethane, anthraquinone and methine compounds, and from 1 to 30 weight percent of a triethanolamine ethoxylate, said triethanolamine ethoxylate having greater than 9 moles of --CH.sub.2 CH.sub.2 O-- units.
A fugitive colorant solution comprising a chromophore having at least one sulfonic acid or carboxylic acid functionality, wherein said chromophore is selected from azo, triphenylmethane, anthraquinone and methine compounds, in an amount sufficient to provide coloration of said solution and at least one molar equivalent of an amine ethoxylate per acid functionality of said chromophore, said amine ethoxylate having the following formula ##STR4## wherein m, n, and p are integers, and the sum of m+n+p is greater than 9.
