Claim:
In a lithographic fountain solution containing water and optionally a water-miscible alcohol, the improvement wherein the solution contains a surfactant-effective quantity of at least one reaction product comprising the following reactants: A) at least one compound of formula I R′(X) 3 (I) wherein each X group is a halogen atom or one X group is a halogen atom and two X groups represent an epoxy oxygen atom, which is attached to two adjacent carbon atoms in the R 1 group to form an epoxy group, and R 1 is an alkanetriyl group containing from 3 to 10 carbon atoms; and B) at least one compound having the formula II R 2 X(AO) n Y (II) wherein R 2 is a substituted or unsubstituted, saturated or unsaturated, organic group having from 1 to 36 carbon atoms; X is —O—, —S—, or NR 3 —where R 3 is hydrogen or a C 1 –C 18 alkyl group; each AO group is independently an ethyleneoxy, 1,2-propyleneoxy, or 1,2-butyleneoxy group, n is a number of from 0 to 200; and Y is hydrogen, or Y can be a mercapto group or an amino group or a C 1 –C 6 alkylamino group in place of a terminal —OH group, provided that when Y is mercapto or an amino group or a C 1 –C 6 alkylamino group, n is at least 1.
