Abstract
The present disclosure includes compositions, methods, and systems including an ink-jet ink comprising a liquid vehicle, a colorant dispersed or dissolved in a liquid vehicle, and self cross-linkable latex particles dispersed in the liquid vehicle. The self cross-linkable latex particle can have at least 0.1 wt % of the self cross-linkable monomer on the surface of the self cross-linkable latex particle providing cross-linking sites on the surface of the self cross-linkable latex particle, and can form an intra- and inter-particle cross-linked latex polymer film after printing the ink-jet ink on a substrate and upon at least partial depletion of the liquid vehicle or a liquid vehicle component.
Claims17
An ink-jet ink composition, comprising:
- a) a liquid vehicle;
- b) a colorant dispersed or dissolved in a liquid vehicle;
- and
- c) self cross-linkable latex particles dispersed in the liquid vehicle, the self cross-linkable latex particles comprising:
- i) at least one hydrophobic monomer,
- ii) at least one acidic monomer, and
- iii) at least one self cross-linkable monomer, the at least one self cross-linkable monomer including at least one keto group, and having the general formula:
- where R is H or CH3;
- X is O or NH;
- Y is CH2OH or a ring structure containing at least one hetero atom;
- wherein the self cross-linkable latex particle has at least 0.1 wt % of the self cross-linkable monomer at the surface of the self cross-linkable latex particle providing cross-linking sites on the surface of the self cross-linkable latex particle, and wherein the self cross-linkable latex particles form an intra- and inter-particle cross-linked latex polymer film after printing the ink-jet ink on a substrate and upon at least partial depletion of the liquid vehicle or a liquid vehicle component.
