NOVEL AND IMPROVED PROCESSES
Electron beam (EB) dye fixation:-
Ciba has evaluated a series of dyes that contain polymerisable vinyl groups; these are available in test quantities as Cibacron EB dyes and are suitable for printing [29]. Following printing with a paste containing a dye monomer and a specially selected cationic monomer, fixation is achieved by electron beam irradiation. This promotes copolymerisation and network formation with other polyvinyl monomers added to the original print paste. The target of 100% dye utilisation is approached and minimal washing-off is required.
