Abstract
The present invention is drawn to a method of generating functionalized latex particulates in a colloidal suspension. The method can comprise steps of protecting functional groups present on polymerizable monomers with photo labile groups to form protected monomers; polymerizing the protected monomers to form a protected polymer; and exposing the protected polymer to a wavelength of light that removes the photo labile groups from the functional groups, thereby forming the functionalized latex particulates. These latex particulates can be used in a wide variety of applications, including in ink-jet ink printing applications.
Claims18
A method of preparing an ink-jet ink, comprising:
- a) preparing functionalized latex particulates in a colloidal suspension, said functionalized latex particulates prepared by:
- i) protecting functional groups present on polymerizable monomers with photo labile groups to form protected monomers,
- ii) polymerizing the protected monomers to form a protected polymer, and
- iii) exposing the protected polymer to a frequency of ultraviolet light that removes the photo labile groups from the functional groups, thereby forming the functionalized latex particulates;
- and
- b) admixing the colloidal suspension with a liquid vehicle and a colorant, wherein an ink-jettable ink-jet ink is formed.
A method of preparing an ink-jettable protective overcoat composition, comprising:
- a) preparing functionalized latex particulates in a colloidal suspension, said functionalized latex particulates prepared by:
- i) protecting functional groups present on polymerizable monomers with photo labile groups to form protected monomers,
- ii) polymerizing the protected monomers to form a protected polymer, and
- iii) exposing the protected polymer to a frequency of ultraviolet light that removes the photo labile groups from the functional groups, thereby forming the functionalized latex particulates;
- and
- b) admixing the colloidal suspension with a liquid vehicle, wherein an ink-jettable overcoat composition is formed.
