| 20100227947 | INK-JET INKS AND ENCAPSULATED PIGMENTS PREPARED BY RAFT REAGENTS - The present disclosure is drawn to methods and compositions directed at encapsulated pigments. As such, an encapsulated pigment can comprise a pigment and a polymer encapsulating the pigment, where the polymer comprises a monomer and a RAFT reagent. Additionally, a method of encapsulating pigments can comprise dispersing a pigment in an aqueous solution to form a pigment dispersion, adding a monomer to the pigment dispersion, adding a RAFT reagent to the pigment dispersion, and polymerizing the monomer using the RAFT reagent in the presence of the pigment to form an encapsulated pigment. Further, the present disclosure provides ink-jet inks comprising the encapsulated pigments. | 09-09-2010 |
| 20100328411 | PRINTING ON VINYL PRINT MEDIA - A system and method of ink-jet printing on vinyl print media can comprise jetting an ink-jet ink onto a vinyl print medium to form a printed image, and applying from 50-100° C. of heat to the printed image. The ink-jet ink can include a colorant, an aqueous liquid vehicle, and core-shell polymer particles. Upon printing and heating, at least a portion of the aqueous liquid vehicle evaporates, the vinyl print medium plasticizes (but does not flow), and the ink-jet ink flows. The fused polymer particles form a film that encapsulates at least a portion of the colorant. | 12-30-2010 |
| 20110065834 | ENCAPSULATED PIGMENT PARTICLES - An encapsulated pigment particle includes a pigment particle core and a polymer encapsulation layer established on a surface of the pigment particle core. The polymer encapsulation layer includes a polymer and a hydrophobe integrated with the polymer. The hydrophobe has the following structure: | 03-17-2011 |
| 20110082235 | METHOD OF MAKING A PIGMENT DISPERSION - A method for making a pigment dispersion can include dispersing pigment particles in an aqueous liquid medium to form a dispersion, adding a first monomer to form a dispersive coating on the pigment particles, adding a second monomer to the dispersion, and forming a polymer coating on the surface of the pigment particles by polymerizing the second monomer with the first monomer, wherein the polymer coating includes at least one urethane linkage or urea linkage. | 04-07-2011 |
| 20110171386 | LATEX POLYMER WITH SPECIFIC COMPOSITION FOR INKJET PRINTING ON VINYL MEDIA - An inkjet printing composition comprises an aqueous liquid vehicle; at least one pigment having a concentration of about 1 to 5 wt %; and a latex polymer having a concentration of about 2.5 to 8 wt % and comprising a polymerized mixture of styrene, butyl acrylate, at least one of methacrylonitrile and acrylonitrile, methacrylic acid, and ethylene glycol dimethacrylate. An inkjet ink printing system comprises a vinyl medium; the at least one inkjet printing composition; and a heating device, wherein the system is configured such that upon applying heat from the heating device to the inkjet ink printed on the vinyl medium, the latex particles fuse, thereby forming a printed image with a film encapsulating at least a portion of the pigment on the vinyl medium. A method of forming a printed image of the latex polymer using the inkjet ink printing system is also provided. | 07-14-2011 |
