Abstract:
PROBLEM TO BE SOLVED: To provide a permanent heat activated transfer printing process for general printing, particularly for printing heat activated ink by an inkjet printer onto paper or other printable substrates as a medium, and heat-activating the ink to transfer a design formed by the ink from the medium to a substrate on which the design is to appear permanently. SOLUTION: The permanent heat activated transfer printing process comprises (a) preparing the inkjet printer, (b) preparing at least one heat activated ink, and (c) transferring the heat activated ink in the form of an image onto an object on which the image is to appear, wherein the transfer process includes printing the heat activated ink on the substrate medium without activating the heat activated ink in the form of the image in the printer, and transferring the image from the substrate medium to the object by heating the heat activated ink. The heat activated ink is formed of a liquid ink composition comprising (i) heat activatable dye solids existing dispersed in a colloidal form in a liquid carrier, finely divided and substantially insoluble in the liquid carrier, and (ii) at least one emulsifying enforcing agent having affinity for the activatable dye solids and capable of sticking to all or part of individual dye solid particles or surrounding them. The emulsifying enforcing agent prevents agglomeration of the colloidal dye solids to prevent separation of the dye solids from the liquid carrier, and stabilizes ink components with the lapse of time.

Abstract:
PROBLEM TO BE SOLVED: To provide a permanent thermal activation transfer printing method by which a thermally activated ink is printed onto a paper as a medium or another printable medium by means of an inkjet printer to heat activate the ink, thereby transferring the design formed by the ink onto the substrate on which the design are to permanently appear from the medium. SOLUTION: A liquid ink composition is composed of a thermal activation solid dye which is appropriately used by the inkjet printer using liquid ink, and of at least one emulsifying enforcing agent shutting down the thermal activation solid dye and at least one solvent, and is adjusted. The liquid ink composition is supplied to the inkjet printer to print the ink composition onto the medium in a desired image by means of the inkjet printer, at a temperature lower than the temperature for actuating the thermal activation solid dye, allowing the image to be transferred from an object to another object at a temperature higher than the temperature activating the thermal activation solid dye so as to transfer the thermal activation solid dye on the object on which the image is to appear.

Abstract:
A color image is digitally printed onto an intermediate transfer medium. The image is subsequently transferred from the intermediate transfer medium to a final substrate, which may be a cellulosic textile, such as cotton. Bonding of the color images is provided by the reaction between compounds selected from each of two chemical groups contained in the intermediate transfer medium. The first group comprises compounds with functional groups capable of reacting with active hydrogen, such as isocyanate or epoxy groups. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. The functional groups of one or both reactive chemical groups may be protected either by blocking with internal or external blocking agents or by a physical barrier such as encapsulating agents. The blocking agents are removed by the application of energy, such as heat, during the transfer of the image from the intermediate transfer medium to the final substrate. The intermediate transfer medium may be comprised of additional components which may be combined with either or both of the above two chemical groups, or applied as separate layers. Examples of such components are a thermally expandable material, an exothermic chemical, a release agent, and/or absorbent material. Transferred images so produced have a soft hand, particularly when applied to a textile, and excellent fade and abrasion resistance.
Abstract:
An image is printed on a medium by means of a computer-driven printer (6) using an ink composition comprising heat-activated dye solids, without activating the dye solids during the process of printing onto the medium. The image is transferred from the medium to the object (8) on which the image is to permanently appear by applying heat and pressure to the medium to activate the dye and transfer the image to the object (8). The liquid form of the ink composition uses a liquid carrier and an emulsifying enforcing agent which has an affinity for the dye. The emulsifying enforcing agent shields the heat-activated dye both prior to, and during, the printing process.

Abstract:
An image is printed on a medium by means of an electrographic device using an ink composition comprising heat activated inks, without substantial activation of the inks during the process of printing the image onto the medium. A molecular sieve added to the ink composition assists activation control. The image is transferred from the medium to the object on which the image is to permanently appear by applying sufficient heat and pressure to the medium to activate and permanently transfer the inks from the medium to an object.
