Definitions

  • Hall Patent No. 2,754,279 represents one successful and satisfactory solution.
  • the concept of reinforcing an image after exposure of the plate has inherent difliculties.
  • the manner in which the image strengthener is applied to the plate surface can make a great deal of difference in the press life of the plate. Care is required. 'For example, when the image strengthener is applied properly, skillfully and uniformly, the plate may be used to reproduce many thousands of copies more than if it is applied poorly. Also, a poorly capped or coated image may not accept ink properly, and be worse than if no strengthener had been applied at all.
  • I provide a presensitized plate structure in which, as received from the manufacturer, the entire exterior surface is provided with the ultimate physical characteristics desired of the image areas in the exposed plate. That is, the exterior surface is hard, durable, abrasion- It is strongly organophilic lithography. When exposed to actinic light in the customary fashion, and then wiped or lightly rubbed with a processing composition involving common solvents, the exterior surface in the non-exposed areas, and the underlying unreacted sensitizer in said areas are quickly, easily and completely removed. An accurate sharpclear image thereby is defined, even in the case of fine half-tone images.
  • My invention has important utility beyond metalbacked presensitized printing plates, and beyond the printing field. Some of these will be brought out hereinafter in the specific examples which follow.
  • the novel plate or sheet structures hereof comprise a base sheet having coated thereover a stable light-sensitive resin layer, e.g., a light-sensitive diazo resin, which upon exposure becomes insolubilized from its initial state.
  • a stable light-sensitive resin layer e.g., a light-sensitive diazo resin
  • the surface of the base sheet underlying the lightsensitive material is receptive to the formation of a firm bond with the in situ insolubilized light-sensitive material.
  • an actinic light-transmittable film or layer of a hydrophobic water-insoluble solvent-softenable resin Coated over and in contact with the light-sensitive material.
  • surface 11 may involve a treatment which protects the sensitizer layer 12 from beingdegraded by any degradative V i W 7 V V characteristics in the base sheet 10.
  • Overlying said lightsensitive layer 12 is an overcoating or layer of an organophilic hydrophobic water-insoluble substantially contin uous, solvent-softenable organic resin film .or coating 13.
  • FIGURE 2 shows the sheet construction of FIGURE 1 afterit has been. exposed to actinic light through a transparency or stencil. During exposure the actinic light passing through the transparency also passes'through resin coating 13 and strikes. the light-sensitive layer in the image areas 12a. I In the latter areas the sensitizer reacts to become insolubilized-and firmly adhered'to the underlying surface 11 of the base sheet 10.. Also in said exposed areas lthe-light-reacted resin firmly bonds .the overlying resin layer 13. In the non-exposed areas 12b the sensitizer remains unreacted and soluble.
  • FIGURE 3 shows the sheet construction of FIGURE 2, after it has been wiped or lightly scrubbed with processing solvent selected with respect to the par- ,ticular material of which layer 13 is composed, and which contains a solvent for the unexposed light-sensitive material.
  • the resin layer 13 is softened and breaks away cleanly along'the lines of demarcation between the exposed and unexposed areas to leave resin areas 13:: coinciding withareas 12a-of exposed reacted sensitizer.
  • the .unexposed light-sensitive material in the non-light struck areas is also washed'away from the plate baring the underlying surface 11, which, in the case of a printing plate, 1 preferably is-hydrophilic in character.
  • the plate, then, and without necessity of further proc- .essing is ready for mounting on the printing press. 7
  • the .lmage areas are strongly organophilic, firm and Wear-resistant.
  • Example I A solution is first prepared by dissolving polyvinylformal resin in ethylene chloride solvent to yield approximately an 8 percent solution.
  • a suitable polyvinylformal resin has a polyvinyl alcohol content of from about 7-9 .percent and a polyvinyl acetate content of from about 95-13 percent, and a percent ethylene chloride solution thereof has a viscosity of about 40-60 cps. at C.

  • lithographic plate structure is prepared by cleaning a smooth-surfaced aluminum sheet, for example with trisodium phosphate followed by treatment with nitric acid solution and rinsing in water. The; sheet is then treated with an aqueous silicatesolution and washed clean of any remaining watersoluble materials.
  • An initially water-soluble light-sensitive diazo resin e.g., a p-diazodiphenylamine-formaldehyde resin, is then coated over the silicate treated surface.
  • the continuous web of presensitized plate is then flow coated 'by passing it (sensitized surface outward) around a roller partially immersed in the coating solution at a web speed of about 1.5 feet per minute.
  • the temperature of. the coating solution in the tank is maintained at room temperature.
  • a dry coating-weight of about 50 mg/ft is applied, the exact coating weight applied being determined by the speed of the web, the temperature of the room and viscosity of the coating solution.
  • the thus coated web, coated side uppermost, is thenair dried, theweb being passed alongside a vented hood.

  • the plate maybe exposed in the manner described in the aforesaid Jewett and Case Patent No. 2,714,066.
  • exposure of the plate to a 35 ampere carbon arc at a distance of about 24 inches for a time of from 1 to Z minutes provides suitable exposure for the light-sensitive diaizo resin in the light-struck areas.
  • the sensitizer in the exposed areas is converted to a water-insoluble character.
  • the physical properties of the resin overlayer in said exposed areas do not seem to change.
  • a Solvent mixture of 2 parts isopropanol and 1 part water by volume is poured liberally onto the plate'surface and spread'uniformly thereover by wiping gently with a soft sponge or cloth mounted on a firm backing such as'a wood block. After a few seconds a gentle rubbing action removes the polyvinyl-formal resin coating from the unexposed areas while virtually none is removed in the exposed .areas.
  • the area being worked should be wet at'all times and it may be necessary to add addi- After the resin coating has been removed, which takes only a few seconds, the entire surface of the plate is-then, treated by wiping it thoroughly with an aqueous desensitizing and gumming solu- ..tion, for example,. a slightly acidified water solution of gum arabic. Thereby any diazo resin remaining in the non-image areas is removed and the underlying silicate treated aluminum .surface in these areas is bared.
  • the image will be clearly visible on the plate, by virtue of the blue color imparted by the pigment, and clearlywill contrast with the treated aluminum surface in the non-image areas. It is thus extremely easy to determine when the image is clearly and accurately brought out.

  • the thickness of a polyvinylformal resin coating having a weight of about 3-4 mg./ft. is in-the order of only about one millionth of an inch, i.e., 0.001
  • a rather heavy coating weight of 120 mg./ft. has a thickness in the order of about four one-hundred-thousandths of an inch, or 0.04 mil.

  • Example II is of different character than the water-soluble light-sensitive resin employed in.

  • the resin overlayer provides the printing surface
  • lightsensitivematerials may now be employed in lithographic plates, even though in and of themselves, they inadequately provide a printing image.
  • Stability of the sensitizer can be high sothat the base sheet coated therewith is presensitized, i.e., the sensitized sheet can be stored for substantial periods of time with the sensitizer remain-" ing stably soluble and light-sensitive.

  • the amount. of diazo applied is just under that which would impart a visible color efiect upon exposure.
  • the diazo surface is then overcoated with a polyvinylformal containing a suitable transparentpigment, in a manner similar to that described in Example 'I. Since color is of primary importance the pigment loading will be most useful in the rangeof 30 to percent of total solids in the overlayer.

Acoating weight of 6O to 120 mg./ft. ordinarily is an optimum weight depending upon the specific desired color levels.
