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;
an uncured epoxy resin component; and
an uncured melamine resin component; and

a solvent composition comprising:
propylene-glycol-monomethyl-ether;
diethylene-glycol-dimethyl-ether; and
propylene-glycol-methyl-ether-acetate.

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 silicone resin which comprises a silsesquioxane component present at about 15 to about 20 weight percent;
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; and

the solvent composition comprises:
propylene-glycol-monomethyl-ether present at about 30 to about 40 weight percent;
diethylene-glycol-dimethyl-ether present at about 10 to about 13 weight percent; and
propylene-glycol-methyl-ether-acetate present at about 10 to about 12 weight percent.

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

4. The ink composition of claim 3 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.

5. The ink composition of claim 4 wherein the ink composition has a viscosity from about 4 to about 6 centipoise at about 25 degrees Celsius.

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

7. 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;
an uncured epoxy resin component; and
an uncured melamine resin component; and

a solvent composition comprising:
propylene-glycol-monomethyl-ether;
diethylene-glycol-dimethyl ether; and
propylene-glycol-methyl-ether-acetate; and

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

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

9. The method of claim 8 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 inert atmosphere.

10. The method of claim 7 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.

11. The method of claims 7 , wherein the pigment material comprises a carbon black particulate.

12. The method of claim 7 , wherein:
the pigment material comprise a carbon black particulate pigment material present at about 3 to about 5 weight percent;
the uncured resin composition comprise:
the uncured silicone resin which comprises a silsesquioxane component present at about 15 to about 20 weight percent;
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; and

the solvent composition comprises:
propylene-glycol-monomethyl-ether present at about 30 to about 40 weight percent;
diethylene-glycol-dimethyl-ether present at about 10 to about 13 weight percent; and
propylene-glycol-methyl-ether-acetate present at about 10 to about 12 weight percent.
