Definitions

  • the novel ink formulation of this invention is a stable emulsion comprising an oleophilic phase and a hydrophilic phase, comprising one or more polyhydric alcohols, a surfactant and polystyrene sulfonate.
  • the specific polymeric surfactants are: polyoxyethylene alcohols, polyoxyethylene esters, polymeric condensation products of ethylene oxide-propylene oxide, the reaction product of ethylene oxide and propylene oxide with ethylene diamine, and polyvinyl pyrrolidone.
  • This invention relates to a novel ink formulation useful in planographic and lithographic printing processes. More particularly, this invention relates to a novel ink formulation useful in connection with lithographic printing processes, whereby the use thereof eliminates the need for separate and repeated dampening of the lithographic master plate between printing of copies.
  • a lithographic master plate is prepared by producing on the surface thereof ink receptive and water receptive areas, the latter being ink repellent areas.
  • the plate When the plate is contacted with an aqueous liquid, the aqueous liquid is attracted to the water receptive areas and then when the ink is applied the ink is selectively attracted by the ink receptive surface of the plate and rejected by the ink repellent areas.
  • the plate bearing the ink in only those selective areas is contacted with a printing blanket. The inked image is transferred to the blanket which in turn transfers the image to the sheet of paper or surface upon which the image is desired.
  • the ink bearing plate is contacted directly with the sheet of paper or other printing surface.
  • the various processes presently in use for preparing printing plates range from lithographic processes, where a design is made on the surface of the material with a water-repellent, ink receptive material such as crayon or lithographic chalk. Photographic processes may also be used wherein light sensitive bi-chrornated gums or light sensitive diazo materials are exposed to an image pattern and the exposed materials are then treated to obtain ink receptive areas. Lithography plates may also be prepared by electrostatic copying methods. Any of these plates may be used with the printing ink of this invention.
  • the plate is then contacted with the printing blanket to which the ink is transferred, and the blanket in turn contacts the sheet of paper upon which the design is to be printed.
  • the ink is transferred from the blanket to the sheet and the entire process is repeated to obtain the individual sheets bearing the design.
  • This process requires the sequential application of Water and ink each time a print is made, and this repeated operation decreases the useful life of the plate. Troubles are also encountered through partial comingling or emulsification of the oil and water on the plate.
  • novel ink formulations of this invention comprise a stable and persistent emulsion of two dissimilar phases; i.e., an oleophilic phase and a hydrophilic phase. These two dissimilar phases are held in a stable emulsion form by the employment of a polymeric surfactant and a small but effective amount of polystyrene sulfonate.
  • the stability of the resultant emulsions of the instant invention is such that the emulsion is storably stable even over extended periods of time while at the same time is capable of being broken by the operation of the press rollers by which they are applied to the master plate during the lithographic printing process.
  • the oleophilic phase of the ink formulations of this invention may be comprised of various materials which are commonly employed in inks useful in lithographic printing processes, and includes such material as pigments, resins, oils, varnishes, gels, waxes, drying agents such as metal soaps, anti-oxidants, and other like materials as are well known to the skilled worker to be useful for such purposes.
  • the hydrophilic phase of the ink formulations of this invention are preferably comprised of such hydrophilic substances as one or more polyhydric alcohols in combination with a polymeric surfactants and polystyrene sulfonate to impart stable characteristics to the ink formulations.
  • the polyhydric alcohols which may be satisfactorily employed either singly or in combination, include glycerine, ethylene glycol, glycerol, propylene glycol, sorbitol, mannitol and the like.
  • the formulations of this invention may be anhydrous,it has been found that satisfactory results are obtained even when about up to 20% by weight of water or up to by weight of an alkanol is incorporated in the polyhydric alcohol fraction.
  • the classes of surfactants are Polyoxyethylene esters of fatty acids; Polyoxyethylene alcohols, polymeric Poly- 01s and Polyvinyl Pyrrolidone, each having specific characteristics as more fully set forth below.
  • the preferred range for the surfactants is from about 1 to 10 percent of the hydrophilic phase of the ink formulation and preferably from about 2 to about 7.5 percent by weight.
  • a polystyrene sulfonate is employed in a small but effective amount as a stabilizer.
  • the lithographic ink of the invention is made by emulsification of the hydrophilic and oleophilic phases by any known manner of creating emulsions.
  • the hydrophilic phase of the ink should comprise from about 15 to about 60 parts with the oleophilic phase comprising from about 85 to about 40 parts of the ink formulation.
  • polymeric surfactants which are preferred are as follows:
  • BRII 92 is commercially available from Atlas Chemical Co. a division of ICI America, Inc.
  • polymeric surfactants examples include Pluronic L-35, Pluronic 10-R5 and Pluronic P- from BASF Wyandotte Corp.
  • Examples of such commercially available surfactants are Tetronic 701 and Tetronic 901 from BASF Wyandotte Corp.
  • Polyvinyl Pyrrolidone having a molecular weight of less than 200,000 examples of commercially available polyvinyl Pyrrolidone are made by GAF Corporation under the designation PVP-K-60 and PVP-K-30. Other sources for the above surfactants may also be used within the scope of the invention.
  • Versa-TL 700 examples of commercially available polystyrene sulfonate made by National Starch and Chemical Corp. and sold under the trademark Versa-TL, as shown in the following examples, Versa-TL 700, Versa-TL 500 and Versa-TL 70 may be used. These polystyrene sulfonates have a molecular weight of 6 to 8 million, 800,000 and 80,000 respectively.
  • EXAMPLE I A.
  • the oleophilic phase of the ink formulation of the instant invention may be prepared as follows:
  • the following materials in the requisite amounts are All of the above materials except for the carbon black pigment are charged into a change can mixer, and are mixed until uniform consistency is obtained. The carbon black is then added slowly with constant stirring. The resultant mixture is then dispersed in a 3 roll mill until the particle size thereof is reduced to less than microns as determined by a Hegmans gauge. The resultant mixture is then employed as the oleophilic phase in thepreparation of the various ink formulations of the instant invention.
  • the hydrophilic phase 'of the ink formulation of the instant invention may be prepared as follows:
  • Formulation number Amount gram Material Ethylene glycol MYRJ 59 (Atlas Chemical Co.)
  • Formulation number teammates-1o Formulation No. 2 did not contain polystyrene sulfonate and dried on the press in 3-4 hours. All of the other formulations containing polystyrene sulfonate were usable for more than 6 hours.
