    摘要： A reactive toner that is energy-activated is printed by means of an electrographic device such as a laser printer. The reactive toner is printed onto a substrate. Toner components that cross-link and bond the printed toner permanently onto the substrate, or another substrate through a transfer process, are activated by the application of energy to react after printing. Reaction of the energy-activated components may be inhibited with blocking or protecting agents. The image is permanently bonded onto the substrate when the protection provided by the protecting agents is removed by the application of energy to the printed toner. The toner may comprise energy-activated components, colorants, color enhancing polymeric materials, binder resins, internal and external additives such as waxes and charge control agents. The energy-activated components have multiple functional groups that react with active hydrogen, components that contain active hydrogen, or components that are capable of conversion to active hydrogen containing groups.

    摘要： Cellulosic fabrics may be dyed by cold-dyeing reactive dyes under weakly alkaline conditions (0.2-1 g/l soda) at 60.degree.-80.degree. C. in the presence of moderate amounts of salt. This is advantageously used for the dyeing of mixed cotton/polyester substrates in a one-bath process with a mixture of reactive and disperse dyes.
