Abstract

Marking fluids and apparatus for marking vinyl substrates, such as through inkjet printing, use aqueous-based fluid vehicles having an amount of a vinyl-softening co-solvent sufficient to cause swelling of the vinyl substrate after water has been driven from the marking fluid.

First claim

What is claimed is:

1. An ink, comprising:
water;
a solvent selected from the group consisting of ethylene glycol phenyl ether, diethylene glycol monopropyl ether, ethylene glycol monobutyl ether, 2-(2-ethoxyethoxy)ethanol, and combinations thereof;
a pigment;
glycereth-26 (LEG-1); and
an acrylic latex binder.

2. The ink of claim 1 , further comprising a second solvent selected from the group consisting of 2-pyrrolidinone, dimethylsulfoxide,-diethylene glycol monomethyl ether, N-methylpyrrolidone, propylene glycol monopropyl ether, diethylene glycol monobutyl ether, triethylene glycol, triethylene glycol monomethyl ether, propylene glycol n-propyl ether, dipropylene glycol methyl ether, and combinations thereof.

3. The ink of claim 1 wherein the ink includes 4 wt % of the acrylic latex binder.

4. The ink of claim 1 wherein the solvent is present in an amount ranging from about 5 wt % to 30 wt % of the ink.

5. The ink of claim 1 wherein the solvent is present in the ink in an amount sufficient to produce a persisting portion of the solvent after the water is removed, and wherein the amount in the ink is about 5 wt %.

6. The ink of claim 1 wherein the solvent is 2-(2-ethoxyethoxy)ethanol.

7. The ink of claim 1 wherein the solvent is to soften a vinyl substrate upon which the ink is printed when the water is removed.

8. An ink, comprising:
15 wt % of 2-pyrrolidinone;
2 wt % of polyethylene glycol (PEG-600);
0.5 wt % of a fluorosurfactant;
2 wt % of a pigment dispersion;
4 wt % of an acrylic polymer dispersion; and
a balance of water.

9. The ink of claim 8 , further comprising 3 wt % of 1,2-hexanediol.

10. A method of printing, the method comprising:
depositing, via inkjet printing, an ink onto a vinyl substrate, the ink comprising:
water;
a solvent selected from the group consisting of ethylene glycol phenyl ether, diethylene glycol monopropyl ether, ethylene glycol monobutyl ether, 2-(2-ethoxyethoxy)ethanol, and combinations thereof;
a pigment;
glycereth-26 (LEG-1); and
an acrylic latex binder; and

heating the deposited ink to remove water, whereby the solvent softens the vinyl substrate.

11. An inkjet pen, comprising:
a body;
an ejection device integral to the body; and
an ink enclosed in the body, the ink comprising:
water;
a solvent selected from the group consisting of ethylene glycol phenyl ether, diethylene glycol monopropyl ether, ethylene glycol monobutyl ether, 2-(2-ethoxyethoxy)ethanol, and combinations thereof;
a pigment; and
an acrylic latex binder.

12. An ink, consisting of:
water;
one or more solvents having a composite Hansen hydrogen bonding partial solubility parameter of about 16 MPa 0.5 or less;
a surfactant;
a pigment; and
an acrylic polymer dispersed in the ink.
