Abstract
Compositions, systems, and methods for protecting an ink-jet produced image printed on a substrate are provided. The composition can comprise a liquid vehicle and latex particulates dispersed in the liquid vehicle, wherein the latex particulates have a surface dielectric constant from 2.0 to 3.0 at room temperature, and a bulk density from 0.90 g/cm3 to 1.10 g/cm3. An alternative composition can comprise a liquid vehicle and latex particulates dispersed in the liquid vehicle, wherein the latex particulates have a reactive surfactant covalently attached thereto.
Claims27
An overcoating composition for protecting a printed image on a substrate, said composition comprising:
- (a) a liquid vehicle void of colorant;
- and
- (b) latex particulates dispersed in the liquid vehicle, said latex particulates having a surface dielectric constant from 2.3 to 2.8 at room temperature, and a bulk density 0.1 g/cm3 less to 0.1 g/cm3 greater than the vehicle density.
