Definitions

  • the present invention relates to a process for fixing dyes on organic materials using colourless cationic compounds that contain at least two polymerisable double bonds with ionising radiation or by irradiation with UV light in the presence of photoinitiators.
  • dyes preferably those containing activated unsaturated groups
  • Dyeing processes are also known in which there are used nonionic colourless compounds containing at least one polymerisable double bond and the subsequent dye fixation is effected by ionising electron beam radiation or by irradiation with UV light in the presence of photoinitiators.
  • the invention relates to a process for dyeing or printing organic material, preferably fibre material, which comprises applying dyes together with a colourless cationic compound containing at least two polymerisable double bonds, as well as additional optional auxiliaries, to said organic material, preferably fibre material, and subsequently fixing the dyes thereon with ionising radiation, or applying said dyes, together with a colourless cationic compound containing at least two polymerisable double bonds, and at least one photoinitiator, as well as additional optional auxiliaries, to said organic material, preferably fibre material, and subsequently fixing the dyes thereon with UV light.
  • the distinguishing feature of the novel process is that dye and colourless cationic compound are applied together so that only a single dyebath or only a single dye liquor is necessary, thereby achieving a markedly higher degree of fixation than in the known processes without a colourless cationic polymerisable compound.
  • the colourless cationic compound can, however, also be applied separately before or after the actual dyeing process.
  • a further advantage is that the process can be carried out at such a low radiation dose that less dye is destroyed, thereby resulting in great brilliance of the dyeing.
  • the fixation process consists in briefly subjecting a fibre material to be dyed, typically textile fibre material, after the treatment with a dye and in the presence of a colourless cationic compound that contains at least two polymerisable double bonds, as well as additional optional auxiliaries, in the wet, moist or dry state to ionising radiation or, in the presence of at least one photoinitiator, to irradiation with UV light
