LATEX-BASED OVERCOAT FOR INK-JET PRINTING APPLICATIONS

Title:

LATEX-BASED OVERCOAT FOR INK-JET PRINTING APPLICATIONS

Document Type and Number:

WIPO Patent Application WO2004089639

Kind Code:

A8

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 0.1 g/cm3 less to 0.1 g/cm3 greater than the vehicle density. 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.
