Definitions

  • the invention relates to the use of certain UV absorbers of the 2- (2-hydroxyphenyl) benzotriazole type as light stabilizers for recording materials for inkjet printing and to the recording materials stabilized by means of these compounds against damage to light.
  • R3 can also be OH substituted cycloalkyl, e.g. 4-hydroxycyclohexyl.
  • R3 as C7-C15 phenylalkyl or alkylphenylalkyl can e.g. Benzyl, 2-phenylethyl, 1-phenylethyl, 3-phenylpropyl, 2-phenylpropyl-2, 4-methylbenzyl or 4-octylbenzyl.
  • Examples of this are the compounds 8), 20), 23), 28), 34), 47) and 51) listed above or mixtures of 3) and 24), of 19) and 29), of 33) and 46) or of 5), 26), 33) and 46).
  • New compounds and as such also the subject of the invention are the compounds of formula IIV, where R and R3 have the meanings given above.
  • the recording material is a two-dimensional sheet which can consist of one or more layers.
  • the carrier layer usually consists of paper or a plastic film or a laminate of such materials.
  • the carrier layer can be coated on one or both sides with a material which is particularly receptive to the ink dyes.
  • the recording material can be transparent, for example in the case of projection foils. In most cases, however, the recording material is not transparent and is read by the supervisor.
  • the UV absorber according to the invention can already be incorporated into the carrier material during the production thereof, for example in the production of paper by adding it to the paper pulp, or in the production of plastic films by adding it to the polymer before extrusion.
  • a second method of application is spraying the carrier material with a solution of the UV absorber in a volatile solvent.
  • a dye-affine layer is applied to the carrier material and in this case the UV absorber according to the invention is added to the coating material.
  • These coating compositions usually consist of a solid filler and a binder, as well as smaller proportions of additives.
  • the dye-binding coating can contain a number of other additives, such as e.g. Antioxidants, light stabilizers (including UV absorbers that do not belong to the UV absorbers according to the invention), viscosity improvers, optical brighteners, biocides or / and antistatic agents.
  • Antioxidants e.g. Antioxidants, light stabilizers (including UV absorbers that do not belong to the UV absorbers according to the invention), viscosity improvers, optical brighteners, biocides or / and antistatic agents.
  • the solvent used is preferably a low-volatility solvent so that the UV absorber remains in the liquid state even after the recording material has been stored for a long time.
  • a volatile auxiliary solvent is usually used to prepare the dispersions which is removed again during the production process of the recording material.
  • low volatility solvents are organic liquids of an oily character and with a high boiling point, such as phthalic acid esters (eg dimethyl, diethyl, dibutyl, diamyl, dihexyl, diheptyl, dioctyl, dinonyl or didecyl phthalate, or dibutyl chlorophthalate) , Glycolic acid esters (e.g.
  • O-acetyl-triethyl) O-acetyl-triethyl
  • tributyl trihexyl, trioctyl, trinonyl or tridecyl citrate
  • benzoic acid esters e.g. butyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tetradecyl , Octadecyl or oleyl benzoate
  • esters of substituted benzoic acids e.g.
  • auxiliary solvents serve to better disperse the UV absorber or its solution in high-boiling solvent.
  • the UV absorber is a liquid of low viscosity which can be dispersed well owing to its polar or hydrophilic character, no solvent is necessary, which is the case with many of the UV absorbers used according to the invention. This can simplify the preparation of the emulsions, and there is no need to recover the auxiliary solvent.
  • the binder of the coating composition is an aqueous solution, a dispersion or a latex
  • the oily phase of the UV absorber or its solution must be dispersed homogeneously in the aqueous phase and this dispersion should have a pot life as long as possible during which the dispersed Do not enlarge oil droplets or the dispersion segregates. This is possible - apart from the use of solvents - by using surface-active agents, by adding colloids to the aqueous phase and by correspondingly intensive mixing and dispersing machines.
  • Suitable dispersing machines are ultrasound devices, turbo stirrers, homogenizers, colloid mills, bead mills, sand mills or high-speed stirrers.
  • Examples of surface-active dispersing aids can be nonionic, amphoteric, anionic or cationic surfactants.
  • nonionic surfactants are esters or ethers of polyethylene oxides or polypropylene oxides or of their copolymers, fatty acid alkanolamides, ethoxylated alkanolamides, partial fatty acid esters of polyols (for example of glycerol, polyglycerol, sorbitol, pentaerythritol or sucrose), N-alkylmorpholines or long-chain amine oxides .
  • amphoteric surfactants are fatty acid amidoalkyl betaine, fatty acid amidoalkyl sultaine, fatty acid imidazoline betaine, N-alkyl- ⁇ -aminopropionic acids or alkylene bis (amidoalkylglycinates).
  • the following surfactants have proven particularly useful as dispersing agents for the oily phase which contains the UV absorber:
  • alkylarylsulfonates can be increased by adding wetting agents, which are also surfactants.
  • wetting agents include sodium dioctyl sulfosuccinate and alkyl naphthalenesulfonates.
  • the binder of the coating composition is applied as a solution in an organic solvent, the UV absorber and the other additives need not be dispersed. They are then added directly to the binder solution or previously dissolved in an organic solvent.
  • TCP 2: 1.
  • the following solution of two anionic surfactants is used as the dispersant: 10 g phenyl sulfonate HSR paste (65%), Hoechst AG 1.3 g Nekal® BX paste (62.5%), BASF AG, 13.7g water.
