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 crosslinking 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.
