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. An ink composition comprising:
a pigment material;
an uncured resin composition comprising:
an uncured silicone resin component comprising a silsesquioxane;
an uncured epoxy resin component; and
an uncured melamine resin component; and

a solvent composition,
wherein the ink composition has a viscosity of from about 4 to about 6 centipoise at about 25 degrees Celsius and the silsesquioxane is present in an amount of from about 15 to about 20 weight percent based on a total weight of the ink composition.

2. The ink composition of claim 1 wherein:
the pigment material comprises a carbon black particulate pigment material present at about 3 to about 5 weight percent;
the uncured resin composition comprises:
the uncured epoxy resin component present at about 0.5 to about 3 weight percent; and
the uncured melamine resin component present at about 1 to about 4 weight percent.

3. The ink composition of claim 2 wherein the carbon black particulate material has a particle size from about 100 to about 150 nanometers.

4. The ink composition of claim 1 further comprising an additive composition.

5. The ink composition of claim 4 wherein the additive composition comprises at least one of:
a dispersant present at about 1.5 to about 3.5 weight percent;
a flow promoter present at about 0.5 to about 1 weight percent; and
a resin strengthener present at up to about 3 percent.

6. An ink coating method comprising:
coating upon a substrate an uncured jet ink composition comprising:
a pigment material;
an uncured resin composition comprising:
an uncured silicone resin component comprising a silsesquioxane component present at about 15 to about 20 weight percent based on a total weight of the ink composition;
an uncured epoxy resin component; and
an uncured melamine resin component; and

a solvent composition; and

curing in-situ the uncured jet ink composition upon the substrate to form a cured ink composition upon the substrate.

7. The method of claim 6 wherein the uncured jet ink composition is thermally cured to form the cured ink composition.

8. The method of claim 7 wherein the uncured ink composition is thermally cured at:
a temperature from about 160 to about 250 degrees centigrade; and
a time period from about 1 to about 20 minutes, in an inter atmosphere.

9. The method of claim 6 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.

10. The method of claim 6 , wherein the pigment material comprises a carbon black particulate.

11. The method of claim 6 , wherein:
the pigment material comprises a carbon black particulate pigment material present at about 3 to about 5 weight percent;
the uncured resin composition comprises:
the uncured epoxy resin component present at about 0.5 to about 3 weight percent; and
the uncured melamine resin component present at about 1 to about 4 weight percent.
