Abstract
A method of formulating a latex ink composition for a specific application temperature can include the steps of determining an application temperature for the latex ink composition; choosing at least one polar monomer having a dielectric constant of at least about 3.1; synthesizing latex particulates using the at least one polar monomer; admixing the latex particulates with a colorant, in a liquid vehicle, to form the latex ink composition; where the latex particulates are film forming at or below the application temperature, and the Tg of the latex particulates is no more than about 15° C. less than the application temperature.
Claims13
A method of formulating a latex ink composition for a specific application temperature, comprising
- a) determining an application temperature for the latex ink composition;
- b) choosing at least one polar monomer having a dielectric constant of at least about 3.1;
- c) synthesizing latex particulates of polymeric masses using the at least one polar monomer;
- and
- d) admixing the latex particulates with a colorant, in a liquid vehicle comprising an aliphatic alcohol and a surfactant, to form the latex ink composition;
- wherein the latex particulates exclude the colorant and are film forming at or below the application temperature, the application temperature being the highest temperature that the latex particulate achieves during ink-jetting, and wherein the Tg of the latex particulates is less than the application temperature, the application temperature minus the Tg being no more than about 15° C.
The method of clam 11, wherein the latex particulates are synthesized from emulsion polymerization.
