Abstract

Abstract A two component tint composition is provided which comprises as a first component, a colorant of the formula: ##STR1## wherein X is a polar group selected from sulfonic acids, sulfonic acid salts, sulfonamides, sulfonates, carboxylic acids, carboxylic acid salts, carboxylic acid amides, carboxylic aldehydes, carboxylic acid esters, ureas, thioureas, nitro groups, hydroxy groups, polyethers, and hydroxyalkylethers; R 1 is selected from nitrogen, oxygen, sulfur, or a sulfur, or a sulfur-containing divalent linking group; R 2 is hydrogen or a lower alkyl group; a is an integer of from 2-10; b is an integer of from 2-10; c and d are each independently selected from one or two; A is a chromophore selected from nitro, nitroso, monazo, diazo, diarylmethane, triarylmethane, acridine, methine, thiazole, indamine, oxazine, or anthraquinone; and B is --H, -alkyl, or -alkyl carboxylate; and as a second component a diluent selected from alkoxylated fatty acids and long chain alcohols, the weight ratio of diluent to colorant being from about 2.5 to about 5 parts diluent to 1 part colorant.
