Abstract:
In an ink composition containing a liquid vehicle and a colorant, the improvement wherein the ink contains a surfactant-effective and/or defoaming-effective quantity of at least one reaction product comprising the following reactants:A) at least one compound of formula I R1(X)3 â€ƒâ€ƒ(I) â€ƒwherein 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 R1 group to form an epoxy group, and R1 is an alkanetriyl group containing from 3 to 10 carbon atoms; and B) at least one compound having the formula II R2X(AO)nY â€ƒâ€ƒ(II) â€ƒwherein R2 is a substituted or unsubstituted, saturated or unsaturated, organic group having from 1 to 36 carbon atoms; X is â€”Oâ€”, â€”Sâ€”, or NR3â€” where R3 is hydrogen or a C1-C18 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 in place of a terminal â€”OH group, provided that when Y is mercapto or an amino group, n is at least 1.
