Definitions

  • the present invention relates to new transfer media, especially those made of paper for dry transfer printing of polyacrylonitrile fibers.
  • the new transfer printing carriers are characterized by the fact that on a flexible, heat-stable base, for example on a paper web, they carry a volatile, ie sublimable or vaporizable pattern at 180 ° to 210 ° C mix of dyes of the two types contains, in which A represents an ether group (for example a methoxy, phenoxy, hydroxyethoxy group), n represents an integer of at most 4, X represents a hydrogen atom or a low molecular weight, optionally substituted alkyl group and Y represents a low molecular weight, optionally substituted alkyl group, where the dyes of types I and II present in the mixture are in a ratio of 1: 3 to 3: 1 to one another.
  • the dye of one type is at least 25% by weight, but preferably at least 35% by weight.
  • several dyes of one type with one or more dyes of the other can also be present in the specified ratio.
  • the invention also relates to a method for printing sheetlike structures made of synthetic or partially synthetic polymeric materials according to the transfer printing principle, which is characterized in that transfer printing supports are used which carry a volatile pattern at 180 ° to 210 ° C, the red element of which consists of a mixture of Dyes of the two types I and II in a ratio of at least 1: 3 to at most 3: 1 of one type of dye to the other.
  • Another object of the invention are printing inks or printing pastes for transfer printing and the substrates, in particular polyacrylonitrile fabrics, knitted fabrics or velvet, as well as more or less multi-pole plush and high-density wallpapers made of polyacrylonitrile and polyacrylonitrile-like materials that have been printed with such transfer printing media, ie that they have a mixture of the type specified as the red element.
  • auxiliary carriers transfer printing carriers
  • transfer printing carriers which are printed with suitable printing inks, are brought into close contact with the substrate to be printed, whereupon the dye is transferred from the carrier to the substrate under the action of heat and possibly pressure.
  • Transfer under reduced pressure e.g. at 80 to 110 mbar is also possible, the transfer temperature being kept lower and / or the transfer speed being increased.
  • Sheet-like structures such as paper, cellophane, cotton fabric, linen fabric, metal foils etc. come into consideration as auxiliary carriers. Paper is preferred.
  • the printing inks can be printed using customary printing processes.
  • composition of the printing inks depends, among other things, on the type of substrate, the printing process and the carrier material.
  • Rotogravure and rotary film printing are particularly suitable printing processes for the production of printed paper auxiliary substrates.
  • Suitable substrates are preferably sheet-like structures, such as nonwovens, felts, furs, foils and, in particular, woven and knitted fabrics made of polyacrylonitrile and polyacrylonitrile-like materials (modacrylic).
  • the production of the starting dyes is known per se and a large number of dyes of the types mentioned are available on the market. Only the Disperse Red 4, 55, 55: 1, 60 and 91 listed in the Color Index of the Society of Dyers and Colorists should be mentioned.
  • the tricyanovinyl dyes of type II are known from the patent literature (see, for example, German Offenlegungsschrift No. 2,741,392 ).
  • the dye mixtures can be prepared by various methods.
  • the transfer printing medium according to the invention is obtained by customary printing methods.
  • These supports produce brilliant red patterns on polyacrylonitrile materials using the transfer printing method, whose lightfastness is surprisingly higher than that of the patterns obtained with the individual dyes of type II.
  • the brilliance of the swatches is also significantly better than that of the swatches of type I dyes and, for practical purposes, almost equal to that of the corresponding swatches of type II dyes.
  • the rub fastness is excellent.
  • Example 1 35 parts of 1-amino-2-methoxy-4-hydroxyanthraquinone are mixed with 40 parts of the dye of the formula 50 parts of a dispersant (lignin sulfonate or condensation product of naphthalenesulfonic acid and formaldehyde) and 100 parts by volume of water are mixed and converted into a finely divided form in a ball mill by grinding for 10 hours.
  • a dispersant lignin sulfonate or condensation product of naphthalenesulfonic acid and formaldehyde
  • the dispersion thus obtained containing about 30% raw color, is pasted with 400 parts of a 10% locust bean gum ether thickener and 500 parts by volume of water.
  • This printing paste is used to print on paper using rotary film printing or gravure printing. If you press this paper for 15 to 60 seconds at 200 ° C with a textile made of polyacrylonitrile fibers, you get a strong brilliant red print with excellent lightfastness.
  • Example 2 20 parts of 1-amino-2ß-hydroxyethyloxy-4-hydroxyanthraquinone are mixed with 30 parts of the dye of the formula 5 to 10 parts of an emulsifier mixture of ethoxylated nonylphenol
  • the printing ink obtained in this way can be used for gravure printing on papers.
  • textiles made of polyacrylonitrile, for example knitted fabrics or velvet can be printed in the transfer process at 190 ° under 100 mbar and a contact pressure of the follower on the transfer paper of approximately 1 g / cm 2, and brilliant red prints of excellent fastness are obtained.
