Benefits of technology

This patent describes a new type of ink that can be used in marker pens. The ink has low viscosity, doesn't clog the markers, and is safe for people and the environment. The ink contains water, a solvent, dye particles, pigment dispersant, and other additives. When the ink is heated, the dye can be transferred to the item being decorated, leaving a vivid image. Overall, this patent provides a valuable tool for creating high-quality decorations.

Problems solved by technology

However this application also relates to using relatively large size aluminum pigments that do not form a stable dispersion.
Other disadvantages of the Graphic Magician inks relate to the use of resins and solvents that are not consumer friendly.
This composition also suffers the disadvantages of using soluble resin and undesirable solvents.
This was accomplished by use of chlorinated solvents which are environmentally unfriendly and would not be accepted in today's commercial market.
The particular ink compositions contained 20% or higher concentrations of solvent and this would be undesirable for commercial nib marker use.
In each case these inkjet ink compositions would not be suitable for use in consumer-based nib markers.
A first issue is the use of solvents and chemicals that are now considered either toxic or environmentally unfriendly.
A second issue is the stability of the ink compositions.
It is difficult to maintain long-term dispersion of pigment-based disperse dye sublimation inks.
If the dye particles aggregate the inks will clog the nib causing failure.
A third issue relates to maintaining an environmentally friendly solvent mixture that will not dry prematurely.
A fourth issue is formulating an ink with low enough viscosity such that the ink is wicked at a desired rate but not so low that the ink will puddle when it first contacts the substrate.
A fifth issue is the inclusion of polymer components where the polymer can soften and adhere to a decorated item.
A sixth issue particularly related to current inkjet inks is the inclusion of certain specialty chemicals necessary for proper long-term operation of ink jet pens but not required or desired if used in a consumer nib marker.
A seventh issue is the percentage of water in the composition.
It is desirable for the ink to be primarily aqueous based but this is not the case with most industrial use inkjet inks.

example 1

[0026]A magenta ink was prepared by media milling Disperse Red 60 with a styrene acrylic acid dispersant for 24 hours to produce a pigment dispersion where the final dye concentration was approximately 16 wt %. The particle size of this dye averaged approximately 100 nm. This dispersion was diluted with distilled water, polyethylene glycol, and biocide such that the final formulation comprised 5% dye, 7% polyethylene glycol, 0.2% biocide and the remainder distilled water with all percents being weight percents. The final viscosity was approximately 1 cps. The ink was placed in a nib-based pen with a synthetic fiber nib such as those from Porex. An image was created by drawing with the pen onto plain paper. The inked image was placed in contact with a polyester shirt and the combination placed in a heat press for 30 seconds at 400° F. to produce a decorated shirt. The ink was tested to confirm that it met ASTM-D4236, CFR1500.14(b)(LHMA)and EN-71 certification for child safety standar...

example 2

[0027]The nib-based marker with magenta ink from above was used to write directly onto a polymer-coated ceramic tile. A non-porous heat-resistant parchment paper sheet was placed over the inked ceramic tile and an iron used to transfer the dye.

Abstract

Provided are a child and environmentally friendly aqueous based heat transfer disperse dye ink compositions suitable for placing an image on an object and processes of their use. The compositions may include a heat transfer disperse dye having a particle size less than 350 nm, and wherein the ink composition may have a viscosity less than 10 cps at room temperature. A process that uses the ink compositions optionally include marking an intermediate substrate, drying the image, optionally heating the intermediate substrate, optionally placing the inked intermediate substrate in contact with a dye receptive surface of a receptive object, and optionally transferring the image to the receptive object by application of sufficient heat and pressure.
