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.
Abstract:
A formulation and method of printing an ink or meltable ink layer having reactive dyes or mixtures of reactive dyes and disperse dyes as colorants. The ink or ink melt layer also includes an alkaline substance, a binder, and optionally, a heat-activated printing additive. Permanently bonded color images are provided by the reaction between the reactive dye and the final substrate, which may be any cellulosic, protein, or polyamide fiber material, or mixtures with polyester. Reaction occurs upon heat activation of the printed ink image.
Abstract:
A method of printing an ink or meltable ink layer which comprises dyes or pigments or other colorants. The ink or ink melt layer comprises compounds with functional groups capable of reacting with active hydrogen, and compounds with functional groups containing active hydrogen, or functional groups capable of conversion to active hydrogen containing groups. An image is printed (6) onto a substrate (9), at a relatively low temperature, so that the ink is not activated during the process of printing (6) on the medium (9). The image is subsequently transferred or permanently fixed on the final substrate (8) by the application of heat and pressure (10), which activates the ink, and bonds the colorant to the final substrate (8). The reactive compounds may be blocked with blocking agents which are removed by the application of heat or other energy during activation of the ink.
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 heatactivated dye both prior to, and during, the printing process.
Abstract:
A color image is printed onto a first substrate, which acts as an intermediate medium, using lithography, intaglio, gravure, relief printing or other printing process which uses plates. The image is subsequently transferred from the intermediate medium to a final substrate, which may be a textile of natural fabric, such as cotton. Bonding and/or cross-linking of the color images are provided by the reaction between compounds selected from each of two chemical groups. 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 are protected either by chemical blocking with blocking agents or by physical barrier such as encapsulating agents. The blocking agents are removed by the application of heat during the transfer of the image from the first substrate to the final substrate.
Abstract:
An image is permanently transferred to a substrate having a cotton component, or other component which is absorbent or porous, from a medium printed with the image by a computer driven printer. A polymer surface preparation material and an ink are transferred by the printer to the medium from a ribbon or ink composition containing the ink and the surface preparation material, without activating the surface preparation material. The image is transferred from the medium to the substrate by applying sufficient heat and pressure to the medium to transfer the ink and the surface preparation material, with the surface preparation material bonding the ink to the substrate.
Abstract:
A method of printing a liquid ink by means of an ink jet printer. The ink contains dyes or pigments or other colorants, a liquid carrier, and compounds with functional groups capable of reacting with active hydrogen, and compounds with functional groups containing active hydrogen, or functional groups capable of conversion to active hydrogen containing groups. One or more emulsifying agents emulsify the liquid ink. An image is printed onto a substrate, at a relatively low temperature, so that the ink is not activated during the process of printing on to the medium. The image is subsequently transferred or permanently fixed on the substrate by the application of heat and pressure, which activates the ink, and bonds the colorant to the substrate. The reactive compounds may be blocked with blocking agents which are removed by the application of heat or other energy during activation of the ink.
