Abstract

A jet ink composition, a jet ink coating method and a resulting jet ink coated article are all predicated upon the jet ink composition which includes in addition to a particulate pigment material and a solvent composition a resin composition. The resin composition includes an uncured silicone resin, an uncured epoxy resin and an uncured melamine resin. Upon thermal cure the uncured resin composition forms a cured resin composition with superior adhesion to substrates such as but not limited to glass substrates, ceramic substrates and metal oxide substrates.

First claim

What is claimed is:

1. A coated article comprising:
a substrate; and
a cured coating located upon the substrate and comprising:
a particulate pigment material; and
a cured resin binder composition binding the particulate pigment material and comprising a cured silicone resin component comprising silsesquioxane, a cured epoxy resin component and a cured melamine resin component;

wherein an adhesion of the cured coating to the substrate is greater than or equal to 4B on a cross hatch adhesion test.

2. The coated article of claim 1 wherein the particulate pigment material comprises a carbon black particulate pigment material.

3. The coated article of claim 2 wherein the cured coating has a thickness from about 2 to about 6 microns.

4. The coated article of claim 2 wherein the cured coating has an optical density from 3 to 5.5.

5. The coated article of claim 1 wherein the substrate is selected from the group consisting of a glass substrate, a ceramic substrate, a metal oxide substrate, a metal substrate, and a polymeric substrate.

6. The coated article of claim 1 wherein:
the coated article comprises a cover lens; and
the coated article may be ultrasonically cleaned with an aqueous alkali detergent solution absent discoloration of the cured coating or delamination of the cured coating from the substrate.

7. A consumer electronic product, comprising:
a housing having a front surface, a back surface and side surfaces;
electrical components provide at least partially internal to the housing, the electrical components including at least a controller, a memory, and a display, the display being provided at or adjacent the front surface of the housing; and
the coated article of claim 1 provided at or over the front surface of the housing such that it is provided over the display.

8. The consumer electronic product of claim 7 , wherein the consumer electronic product is a mobile phone, portable media player, notebook computer or tablet computer.
