Definitions

  • the present invention relates to a novel process intended to prevent smudging the ink on sheets which have just been printed, by the use of appropriate additives.
  • This novel process applies more particularly, but not exclusively, to printing requiring the use of inks with a base of synthetic resins, mineral or vegetable oils and heavy solvents which are generally designated as fatty inks.
  • Typical oflset and typographical inks that may be utilized in the present invention are known in the prior art.
  • numerous resins are disclosed as the vehicles for ink compositions.
  • petroleum resins, heat-polymerized rosin, phenolic resins, and chlorinated rubbers are disclosed on pages 153-4.
  • This invention solves the problems of the prior art by a novel process according to which there is added to the inks, in printing, both in off-set and typographic processes, a compound containing a combination of a polysaccharide compound and a derivative of a fluorocarbon suspended in an agent such as Freon TF (trichlorotrifluoroethane) with or without addition of a WaX-iiS6lf suspended in an agent such as glycerophthalic resin-a silicone and possibly deodorized mineral oil and linseed oil, these novel compounds eliminating smudging and being incorporated either at the time of making the ink, and preferably at the end of fabrication, i.e., before conditioning, or at the very moment of use, the mixing then being carried out either by simple manual or electrical agitation.
  • Wax composition As an example, the following Wax composition was prepared:
  • Glycerophthalic resin for example, resin R S 73 of R.V.A.
  • Molecular light-weight polyethylene wax 100 Linseed oil 20 Parts Wax mixture 216
  • Rice starch 360 Fluorocarbon mixture 360 silicone 11 To improve the homogenization of the composition it is possible to add:
  • This composition is then added at a rate of 6 to 9% of the total printing ink composition including ink and antismudging composition, at the moment when the fabrication of the ink is in its final stage, i.e., before its conditioning.
  • composition can be incorporated in the ink, no longer at the moment of its fabrication, but of its use. All that is required is to perform the mixing either manually or With an electric agitator.
  • the height of the stacks of printed sheets can be increased by applying the novel process, thus decreasing the losses of time due to frequent handling required in the old processes because of the need for reducing to a minimum the pressure exerted by the weight of the superposed sheets.
  • the novel compound does not harm the quality of the ink, thus retaining a brillance which is often desired.
  • the wax plays its protective role of an anti-adhesive agent while the trichlorotrifluoroethane, continuing to evaporate, causes a slight gaseous cushion further reducing the risks of smudging even when the pile of papers is sufficiently high to cause a considerable pressure on the lower sheets.
  • the anti-smudging composition which has just been given by Way of example, does not limit the scope of the invention which extends not only to similar compounds whose constituent proportions can vary, but also to compounds deriving from said combination by simple substitution of one of the constituents by one of its chemical equivalents.
  • the preferred polysaccharide example could be replaced by any other starch such as wheat or corn starch; the Freon or trichlorotrifluoroethane by another forane; and the glycerophthalic resin by other resins or even by other equivalent vehicles: linseed varnish, for example.
  • an offset or typographical printing ink containing a base of synthetic resins, mineral of vegetable oils, and a heavy solvent, the improvement which consists of including from about 6 to 9% by weight, based on the total composition, of an anti-smudging composition comprising a combination of a starch, and a telomer of tetrafluoroethylene.
  • composition as in claim 1 wherein the starch is selected from the group consisting of rice, wheat and corn starches.
  • composition as in claim 1 comprising additionally in the anti-smudging composition a light-weight wax suspended in glycerophthalic resin.
  • composition as in claim 4 comprising additionally an oil selected from the group consisting of silicone oil, linseed oil, mineral oil and mixtures thereof.
