Claims19
An ink composition, comprising:
- a liquid vehicle;
- a colorant system;
- and
- a polyurethane vinyl hybrid latex;
- wherein the polyurethane vinyl hybrid latex includes a polyurethane polymer and a vinyl polymer that is in-situ polymerized and cross-linked with the polyurethane polymer;
- and wherein the vinyl polymer is selected from the group consisting of ethylenically unsaturated hydrocarbons, esters of acrylic acid or methacrylic acid, amides of acrylic acid or methacrylic acid, vinyl amides, vinyl esters, vinyl-containing cyclic compounds, and combinations thereof.
An ink composition, comprising:
- a liquid vehicle;
- a colorant system;
- and
- a polyurethane vinyl hybrid latex;
- wherein the polyurethane vinyl hybrid latex comprises polyurethane polymers that include polypropylene glycol (PPG), isophorone diisocyanate (IPDI), dimethylolpropionic acid (DMPA) and siloxane containing diol or per-fluorinated ether diol.
An ink set comprising at least one ink selected from the group consisting of black, cyan, magenta and yellow inks;
- wherein the at least one ink comprises a liquid vehicle, a colorant system, and a polyurethane vinyl hybrid latex;
- wherein the polyurethane vinyl hybrid latex includes a polyurethane polymer and a vinyl polymer that is in-situ polymerized and cross-linked with the polyurethane polymer;
- and wherein the vinyl polymer is selected from the group consisting of ethylenically unsaturated hydrocarbons, esters of acrylic acid or methacrylic acid, amides of acrylic acid or methacrylic acid, vinyl amides, vinyl esters, vinyl-containing cyclic compounds, and combinations thereof.
A method of inkjet printing over a prolonged period of time comprising jetting an ink onto a media substrate;
- wherein said ink composition comprises a liquid vehicle, a colorant system, and a polyurethane vinyl hybrid latex;
- wherein the polyurethane vinyl hybrid latex includes a polyurethane polymer and a vinyl polymer that is in-situ polymerized and cross-linked with the polyurethane polymer;
- and wherein the vinyl polymer is selected from the group consisting of ethylenically unsaturated hydrocarbons, esters of acrylic acid or methacrylic acid, amides of acrylic acid or methacrylic acid, vinyl amides, vinyl esters, vinyl-containing cyclic compounds, and combinations thereof.
A method of making an ink composition comprising combining from about 0.01 wt % to about 10 wt % of a polyurethane vinyl hybrid latex with from about 0.1 wt % to about 10 wt % of a colorant system and with a liquid vehicle;
- wherein the polyurethane vinyl hybrid latex includes a polyurethane polymer and a vinyl polymer that is in-situ polymerized and cross-linked with the polyurethane polymer;
- and wherein the vinyl polymer is selected from the group consisting of ethylenically unsaturated hydrocarbons, esters of acrylic acid or methacrylic acid, amides of acrylic acid or methacrylic acid, vinyl amides, vinyl esters, vinyl-containing cyclic compounds, and combinations thereof.
