Reaction products prepared by processes which comprise reacting:

Polyfluorinated compounds useful as surfactants, foam control agents and/or rheology modifiers

Lithographic fountain solutions containing a surfactant-effective quantity of at least one reaction product comprising the following reactants: (A) at least one compound of formula IR(X)&#x2003;&#x2003;(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 Rgroup to form an epoxy group, and Ris an alkanetriyl group containing from 3 to 10 carbon atoms; and (B) at least one compound having formula IIRX(AO)Y &#x2003;&#x2003;(II)wherein Ris a substituted or unsubstituted, saturated or unsaturated, organic group having from 1 to 36 carbon atoms; X is &#x2014;O&#x2014;, &#x2014;S&#x2014;, or NR&#x2014; where Ris hydrogen or a C&#x2013;Calkyl 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&#x2013;Calkylamino group in place of a terminal &#x2014;OH group, provided that when Y is mercapto or an amino group or a C&#x2013;Calkylamino group, n is at least 1.
