    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 translation: 将彩色图像数字印刷到中间转印介质上。 随后将图像从中间转印介质转移到最终的基底，其可以是纤维素织物如棉花。 通过从中间转印介质中包含的两个化学基团中的每一个中选择的化合物之间的反应提供彩色图像的结合。 第一组包括具有能够与活性氢例如异氰酸酯或环氧基团反应的官能团的化合物。 第二组包括具有含有活性氢的官能团的化合物，或在转化过程之后具有含有活性氢的官能团的化合物。 一个或两个反应性化学基团的官能团可以通过用内部或外部封闭剂或物理屏障例如封装剂阻塞来保护。 在将图像从中间转印介质转移到最终基底期间，通过施加能量（例如热）来除去封闭剂。 中间转印介质可以由可以与上述两个化学基团中的任一个或两个组合的另外的组分组成，或者作为单独的层施加。 这些组分的实例是热膨胀性材料，放热化学品，脱模剂和/或吸收材料。 如此生产的转印图像手感柔软，尤其适用于纺织品时，具有优异的褪色和耐磨性。

    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: A media for receiving a printed image during sublimation or heat activated liquid ink printing, and for transferring the image to a final substrate during subsequent heat transfer and activation. The media improves the quality of the finally transferred image and reduces the energy required to effect the transfer of the sublimation dyes. The media comprises multiple layers, including a feathering control layer containing a non-reactive, non-porous material; a dye screening layer, comprised of a porous material, which holds solid dye particles close to the surface of the media, while allowing other materials in the liquid ink to pass through; an absorbent liquid retaining layer; and a support layer. An optional permeation control layer allows liquids, such as aqueous or non-aqueous solutions, to pass through to subsequent layers during printing, while preventing dye vapor from penetrating beyond the dye screening layer during the final transfer step. The screening and/or absorbent layers may contain chemicals that produce an exotherm upon application of sufficient heat.

    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: The present invention relates to the field of digital printing, for example using a thermal printer and sublimation inks to form an image. In one aspect of the invention there is provided a method of digital printing of ink comprising dyes or pigments as colorants, comprising printing an image onto a substrate to form a printed image on the substrate, and subsequently activating the ink to permanently fix the printed image on the substrate, wherein the activating comprises bonding and/or cross-linking of the ink image on the substrate by the reaction between: a reactant comprising a compound with a functional group capable of reacting with active hydrogen, and a co-reactant comprising a compound with a functional group containing active hydrogen. Another aspect of the invention relates to transfer printing, in which an image is printed onto an intermediate substrate to form a printed image on the intermediate substrate, and subsequently transferred a final substrate by activating the ink to permanently fix the printed image on the final substrate.
