Improved fugitive tints are provided wherein such tints are characterized as having from 2 to about 300 repeating alkyleneoxy capped units in the molecule and having a dyestuff molecule attached to the alkyleneoxy capped units. The solubility of the tint compositions can be altered by varying the number of alkyleneoxy capped units in the tint molecule. The fugitive tints are characterized by the formula R{A--(alkyleneoxy constituent).sub.n R.sub.1 ].sub.m }.sub.x wherein R--A is an organic dyestuff molecule, A is a linking moiety in said organic dyestuff molecule selected from the group consisting of N, O, S, or CO.sub.2, the alkylene moiety of the alkyleneoxy constituent contains from 2 to about 4 carbon atoms, n is an integer of from 2 to about 300, m is 1 when A is O, S, or CO.sub.2 and 2 when A is N, x is an integer of from 1 to about 5, and the product of n times m times x (n.multidot.m.multidot.x) is from 2 to about 300, and R.sub.1 is ##STR1## and sulfonates and sulfates thereof in which R.sub.2 is H, OH, an alkyl moiety containing up to 20 carbon atoms or an alkyl substituted carbonyl moiety containing up to 20 carbon atoms, j and k are OH, OM or OR.sub.3 wherein M is a cation moiety of an alkali metal, an alkaline earth metal or ammonia and R.sub.3 is an alkyl moiety containing up to 20 carbon atoms.
