Abstract
Abstract An ink composition having a pH of about 5 to about 10 contains a colorant, a liquid carrier and less than about 5 wt. % of a desizing agent. The desizing agent may be (1) poly(oxyalkylene) modified compounds of sorbitan esters, fatty amines, alkanol amides, castor oil, fatty acid, fatty alcohol; (2) hydrophilic poly(dialkyl-siloxanes); (3) fatty imidazolines; (4) fatty ester modified compounds of phosphate, sorbitan, glycerol, poly(ethylene glycol), sulfosuccinic acid, sulfonic acid, alkyl amine; (5) quaternary alkosulfate compounds; (6) poly(propylene oxide)--poly(ethylene oxide) copolymers; (7) poly(alkylene glycol); or (8) mixtures thereof.
