A method of printing using an ink or meltable ink layer which comprises dyes, pigments or other colorants. Bonding and/or crosslinking of the colorants is 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. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. Either the first group or the second group is present in the ink, and an image is printed with the ink onto a substrate. The substrate comprises either the first or second group, as appropriate, to set up a later reaction with the ink. The reaction is delayed until the image is subsequently transferred to another substrate or is permanently fixed on the substrate, by the presence of protecting or blocking agents, which are removed by the application of heat or other energy. Upon reaction, the colorant is bonded to the substrate.
