Claim:
A phase change ink composition comprising: a wax; an optional colorant; and a modified polysaccharide salt, wherein the modified polysaccharide salt is a compound of the formula wherein m is an integer of from about 5 to about 15; wherein n is an integer of from about 70 to about 200; wherein R 1 , R 2 , R 3 , and R 4 are the same or different and wherein R 1 , R 2 , R 3 , and R 4 are each independently selected from (i) an alkyl group, which can be linear or branched, saturated or unsaturated, cyclic or acyclic, substituted or unsubstituted alkyl, and wherein hetero atoms may optionally be present in the alky group, (ii) an aryl group, which can be substituted or unsubstituted aryl, and wherein hetero atoms may optionally be present in the aryl group, (iii) an arylalkyl group, which can be substituted or unsubstituted arylalkyl, wherein the alkyl portion of the arylalkyl can be linear or branched, saturated or unsaturated, cyclic or acyclic, and substituted or unsubstituted, and wherein hetero atoms may optionally be present in either the aryl portion or the alkyl portion of the arylalkyl, (iv) an alkylaryl group, which can be substituted or unsubstituted alkylaryl, wherein the alkyl portion of the alkylaryl can be linear or branched, saturated or unsaturated, cyclic or acyclic, and substituted or unsubstituted, and wherein hetero atoms may optionally be present in either the alkyl portion or the aryl portion of the alkylaryl group, provided that at least one of R 1 , R 2 , R 3 , and R 4 is a long chain alkyl group having from about 8 to about 48 carbon atoms.
