Abstract
Process for dyeing or printing organic material, in particular fibre material which comprises applying dyes containing no polymerizable double bond together with at least one colorless cationic compound containing at least one polymerizable double bond and, if desired, one or more colorless nonionic compounds containing at least one polymerizable double bond and, if desired, further auxiliaries to the fibre material and then fixing them by means of ionizing radiation, or applying dyes containing no polymerizable double bond together with at least one colorless cationic compound containing one polymerizable double bond, and if desired, one or more colorless nonionic compounds containing at least one polymerizable double bond and at least one photoinitiator and also, if desired, further auxiliaries to the fibre material and then fixing them by means of UV light.
