Abstract

Described herein is a composition that can be used for treating media. The composition includes an organosilane treated water dispersible organic acid salt, a water soluble organic acid salt, a chelating agent, and an optical brightening agent.

Description

Background technique [0001] Printing media are usually made of interlaced cellulose fibers of wood pulp. This use of wood pulp consumes a considerable amount of trees in the world. Global environmental pressures have forced the paper industry to use recycled fibers and non-wood pulp for its media. When used in digital printing applications such as inkjet printing, media made from recycled fibers and synthetic fibers other than wood pulp have poor performance. Summary of the invention [0002] This document describes a composition for processing media for printing. The composition includes organosilane treated organic acid salt, chelating agent, and optical brightener (OBA). Treatment with the composition can improve the performance of the media in inkjet printing applications. [0003] The term "inkjet printing" generally refers to a digital printing operation in which fluid is distributed on a medium. Examples of fluids used in inkjet printing applications include inks, dyes ...
