Abstract
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 2 CH 2 O-- units and is present in a molar excess per acid functionality of the chromophore.
