摘要:
An aqueous ink jet ink composition comprising pigment, water, and an (A n -B m ) block copolymer wherein n represents the degree of polymerization of A and m represents the degree of polymerization of B, wherein A is styrene, and B is acrylic acid.
摘要:
Disclosed is an ink composition which comprises an aqueous liquid vehicle, a dye, and a vesicle-forming lipid, wherein vesicles of the lipid are present in the ink.
摘要:
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.
摘要:
A siloxane-containing ink composition for variable data lithographic printing includes a nano-particle polymer or blend of nano-particle polymers, wherein the polymer or polymers of the blend are water dispersible at temperatures below 100 degrees Celsius; and solids content is in an amount of greater than 25 percent by total weight.
