Nov 15, 2007

Appl. No.:

12/743362

Inventors:

Hui Liu - San Diego CA, US
Phillip C. Cagle - San Marcos CA, US
David Michael Ingle - San Diego CA, US

International Classification:

C09D 11/10
C09B 67/22

US Classification:

523206, 524502

Abstract:

The present invention is drawn to an encapsulated pigment. The pigment can be encapsulated by both a first polymer layer and a second polymer layer, with the second polymer layer encapsulating the first polymer layer and/or the pigment. The first polymer layer can have less than 2 wt % polymerized acid monomer. The second polymer layer is more hydrophilic than the first polymer layer, and is present at a weight ratio of first polymer layer to second polymer layer of greater than about 1.5:1. Methods of forming an encapsulated pigment are also presented.

International Classification:

B41J 2/015

US Classification:

347 21

Abstract:

The present disclosure provides a method of inkjet printing on non-porous media comprising inkjet printing a fixer fluid on the non-porous media and inkjet printing an ink onto the non-porous media, where the printing of the ink is within 125 milliseconds of the printing of the fixer fluid. Thus, the ink is printed to contact the fixer fluid within 125 milliseconds of each being printed. In one example, the fixer fluid can comprise a liquid vehicle including water and co-solvent having a boiling point from 160 C. to 250 C., a surfactant, and a cationic polymer; and the ink can comprise an anionic pigment dispersion.
