Definitions

  • the present invention relates to a preparation comprising a light stabilizer, its use for the production of a transfer medium, a process making the same, as well as a transfer medium and its use.
  • Transfer printing denotes the printing of different materials, such as textiles, using transfer media.
  • Transfer media are printed by sublimable dyes which are subsequently transferred onto the materials to be printed via sublimation using a thermal transfer press.
  • Transfer printing is an increasing market due to the enormous variability of materials to be printed at reasonable costs, e.g. in communications (banners, displays, soft signage, fine arts, flags, entertainment, etc.), fashion (caps, costumes, dresses, jackets, scarfs, shirts, etc.), sportswear and other fields.
  • WO 00/06392 discloses a transfer paper, in particular for inkjet printing, provided at least on the side to be printed, with a release or barrier layer, the layer having a porosity of at most 100 ml/min.
  • US 2012/0160119 describes a method for producing transfer papers by applying a first aqueous liquid to the front side of a paper, which is to be printed, the first aqueous liquid comprising ammonium polyacrylate.
  • US'1 19 further suggests including additives into the first aqueous liquid, such as Si0 2 or silicate particles, cellulose derivatives, or polyhydric alcohols.
  • UV radiation in the sense of the present invention refers to electromagnetic radiation having a shorter wavelength than visible light, e.g. a wavelength from 10 nm to 400 nm. UV radiation may be classified in near UV (290- 400 nm), far UV (180-290 nm) and vacuum UV (below 180 nm).
  • the term UVA is used to represent a wavelength range between 320 and 400 nm
  • UVB is defined as radiation having a wavelength of between 290-320 nm
  • UVC represents a range of below 290 nm.
  • UV radiation below 290 nm is absorbed by the atmosphere and thus not present in the normal environment. UV radiation is present in sunlight, constituting about 10% of the total light output of the sun and may be synthetically produced e.g. by mercury-vapour lamps.
  • UV radiation is known to cause chemical reactions, such as degradation of dyes and material surfaces, which is often associated with a bleaching of the dye or a yellowing of the materials.
  • UV degradation is a common problem in products, particularly pigments, dyes (“phototendering”) and polymeric materials, exposed to sunlight.
  • Particularly susceptible to UV degradation are polymers, such as polypropylene, polyethylene and polyester polymers.
  • dyes having a functional light absorbing group such as anthraquinones, quinophtalones, azo/diazo, styryl, oxazine, xantene, methane/azomethine groups may form radicals, which can react with oxygen (photooxidation) causing degradation of the dye and/or the polymer.
  • light stabilizing additives can be classified due to its function in UV absorbers, quenchers, radical scavengers, secondary anti-oxidants or peroxide decomposers.
  • UV absorbers absorb UV radiation in competition with chromophores, which are part of a material to be protected (e.g. dye or polymer).
  • the aim is to prevent chromophores from being transferred into an excited state, which may cause formation of radicals. If some molecules are already at an excited state, quenchers may bring the chromophore back to its ground state. The quencher accepts the energy of the chromophore and releases the energy as harmless heat or radiation. Radicals, which may cause degradation, may be rendered harmless by so-called radical scavengers.
  • Hindered Amine Light Stabilizers (HALS) and phenolic derivatives are exemplary radical scavengers. Any resulting peroxide may be decomposed by peroxide decomposers, particularly based on thioethers and phosphites.
  • Modification of materials with light stabilizers usually requires large amounts of potentially harmful compounds to be incorporated into a bulk or elaborate coating processes using these compounds together with harmful solvents.
  • the inventors have now found preparations for use in producing transfer media, which allow a sublimation of light-stabilizers from a transfer medium to a material to be light-protected.
  • Such sublimation process provides a solvent-free modification of material surfaces at high throughput, since continuous processes are possible.
  • the process according to the invention particularly allows simultaneous printing of materials with sublimation inks and light-stabilizing modification of the same in a one-step process.
  • the present invention relates to a preparation comprising
