Definitions

  • DeLaHunt ABSTRACT Sheet material is provided which is useful in image transfer techniques whereby an image of an original is formed on a suitable receptor.
  • thermographically induced transfer of a fusible coating from a source sheet to a receptor sheet by infrared irradiation of an adjacent original has several drawbacks inherentin this technique. For example, spotty, incomplete, or blurred images are often obtained since the heat generated by absorption of the radiation is attenuated by the multiple layers before it reaches the fusible coating on the source sheet. Furthermore, such technique is not suitable for obtaining more than one color image on a single receptor without cutting up the original. Another drawback is the inability to proof the image prior to its transfer from the source sheet. Moreover, such technique is not useful for multiple transfers wherein an image of one color is to be superimposed on the same image of a different color.
  • a sheet material useful in image transfer techniques whereby a copy of an original is first made after which a fusible coating on the sheet material is transferred thermographically in an imagewise manner to a receptor.
  • the sheet material of the invention comprises:
  • an imageable layer coated over one major surface of said backing said imageable layer being capable of providing infrared-absorptive image areas upon exposure and development;
  • the imageable layer of the novel sheet material can comprise various materials (e.g., those which are imaged by exposure to a heat pattern; those which are imaged by exposure to visible light; or those which are imaged by exposure to ultraviolet radiation).
  • the novel sheet material is used, in one manner, according to the following procedure:
  • the heat-fusible layer is colored (with dispersed dye or pigment) although for some applications the heat-fusible layer need not be colored.
  • heat-fusible layers which are oleophilic can be used in the preparation of lithographic plates re gardless of color.
  • the novel sheet material also permits one to proof the intended image prior to its transfer from the fusible layer to the receptor.
  • Another advantage derived from the use of the novel sheet material is that transferred images can be obtained wherein one color is superimposed on another color with exact registration. This result is obtained by imaging a first novel sheet after which the heatfusible layer of the first sheet is placed against the heat-fusible layer of a second novel sheet (having a heat-sensitive imageable layer) to form a sandwich construction. When the sandwich construction is then exposed to brief intense infrared radiation, the second sheet, in image areas, becomes infraredabsorptive. Upon separation of the two sheets, the heat-fusible layer of the first sheet, in image areas, is transferred to the heat-fusible layer of the second sheet.
  • the heat-fusible layer in image areas, is transferred to the receptor (upon separation of the sheets) whereby the transferred image comprises one color superimposed on another color, i.e., yielding the resultant color mixture. For instance, when the first heat-fusible layer is yellow and the second heat-fusible layer is blue, the resultant color is green.
  • FIG. 1 shows the sheet material of the invention
  • FIG. 2 shows one method by which the novel sheet is imaged
  • FIGS. 3 and 4 show a method whereby an image of a graphic original is formed on a receptor.
  • sheet material 10 comprising a thin, flexible backing 12 which is transparent to infrared radiation.
  • Backing l2 ordinarily is visibly transparent although it could be translucent so long as it is transparent to infrared radiation.
  • Representative backings include thin (e.g., 0.25 mil to 4 mils) plastic films (e.g., polyester, polystyrene, celluose acetate), map overlay tracing paper, glassine paper, etc. It is highly preferable that one major surface of backing 12 be quite smooth so that heat-fusible layer 16 will cleanly transfer therefrom in the processes described hereinafter.
  • Imageable layer 14 coated over one major surface of backing 12 is of a type which will form infraredabsorptive image areas when exposed and developed.
  • Layer 14 may comprise, e.g., any of the visibly heatsensitive systems described in Miller et al (US. Pat. No. 2,663,654) which relates to a system comprising an iron salt of a long chain fatty acid and a phenol coreactant; Owen (US. Pat. No. 2,910,377) which relates to a system comprising a silver soap of a long chain fatty acid and suitable reducing agent; Newman et al. (US Pat. No.
  • Layer 14 may also comprise a conventional light-sensitive layer, e.g., conventional wet silver photographic emulsion.
  • Layer 14 may also comprise material which is imageable by exposure to ultraviolet light (e.g., diazo resin overcoated with, or physically mixed with, a water-insoluble resinous polymer according to the techniques described in US. Pat. No. 3,671,236 (Van Beusekom)).
  • material which is imageable by exposure to ultraviolet light e.g., diazo resin overcoated with, or physically mixed with, a water-insoluble resinous polymer according to the techniques described in US. Pat. No. 3,671,236 (Van Beusekom)).
  • Heat-fusible layer 16 is a continuous coating which is non-tacky at room temperature.
  • Layer 16 can be opaque, translucent, or transparent so long as it is transparent to infrared radiation. At elevated temperatures (e.g., 60 C. to 210 C.) layer 16 becomes quite tacky and fuses.
  • Preferably layer 16 has a rather sharp fusing or melting point.
  • Layer 16 may be colored by the use of conventional dyes or pigments.
  • layer 16 comprises a mixture of resin and wax.
  • Resins which can be used include both natural and synthetic or mixtures thereof.
  • Representative resins include rosins, hydrogenated rosins, rosin esters, copal, coumarone indene resins, polyterpene resins, phenolic rosins, vinsol, polyamide resins, ketone aldehyde resins, acrylic acid ester derivative polymers (e.g., polyethyl acrylate, butyral methacrylate), polystyrene and low molecular weight styrene copolymers (e.g., M. W. 20,000 to 75,000) and other similar resins.
  • rosins include rosins, hydrogenated rosins, rosin esters, copal, coumarone indene resins, polyterpene resins, phenolic rosins, vinsol, polyamide resins, ketone aldehyde resins, acrylic acid ester derivative polymers
  • Waxes which can be used include natural waxes, petroleum waxes, and synthetic waxes.
  • Representative waxes include beeswax, carnuba wax, montan wax, ceresin wax, esparte wax, candlelilla wax, Japan wax, paraffin wax, petroleum, microcrystalline wax, fatty diamide wax, polyester wax, and other similar waxes.
  • the resin and wax are typically mixed together by hot melt techniques, sand milling techniques in solvent media, or by dissolving the materials in a common solvent.
  • the amount of wax used is typically zero to 50% by weight of the resin component with about 30% by weight being a common loading.
  • the amount and type of the wax component used is selected so as to provide for a rather sharp melting or fusing point at a temperature in the range of 60 C. to 210 C. It may be said that better transferred image definition is obtained when using fusible layers having relatively sharp melting or fusing points.
  • additives or modifying agents such as plasticizers, fluidizing agents, lubricating agents, etc., may also be used to assist in obtaining the desired melting or fusing point for the heat-fusible layer.
  • the heat-fusible layer is readily and easily applied to the backing of the sheet material using, e.g., solvent or dispersion coating techniques.
  • solvent or dispersion coating techniques include knife coating, roll coating, rotogravure coating, air knife coating, curtain coating, etc.
  • the typical thickness for the heat-fusible layer is about 0.125 mil to 1 mil. Preferred thicknesses range from about 0.3 mil to 0.6 mil.
  • FIG. 2 there is shown one method whereby the novel sheet is imaged.
  • Sheet material having a visibly heat-sensitive imageable layer 14
  • graphic original 20 having infrared-absorptive areas 22, in the manner shown.
  • graphic original is briefly exposed to intense infrared radiation whereby infrared-absorptive image areas 22a corresponding to the image areas of the original are formed in heat-sensitive layer 14.
  • the imaged sheet material is also useful as a projection transparency.
  • a preferred technique for imaging the novel sheet in the above-described manner is by passing the superimposed graphic original and novel sheet through a conventional thermographic copying machine (e.g., a Thermofax machine available from Minnesota Mining and Manufacturing Company).
  • a thermographic copying machine e.g., a Thermofax machine available from Minnesota Mining and Manufacturing Company.
  • a silicone-coated carrier sheet or other suitably coated release sheet
  • carrier sheets are typically plastic films (e.g., cellulose acetate, Teflon, cellulose acetate propionate).
  • the novel sheet After the novel sheet has been imaged as shown in FIG. 2, it is placed against a suitable receptor 30 in the manner shown in FIG. 3, after which the imaged copy sheet is exposed to intense infrared radiation (e.g., in a conventional thermographic copying machine) whereby the heat-fusible layer, in areas 22b, fuses and becomes tacky. As a result, portions 22b of the heatfusible layer adhere to receptor 30.
  • portions 22b of the heat-fusible layer 16 remain firmly adherently bonded to the surface of receptor 30. Since portions 22i correspond to the image areas of the graphic original, and when heat-fusible layer 16 is colored, a colored image of the original appears on the receptor.
  • the imaged sheet material is still useful as a projection transparency at this stage so long as it is transparent to visible light.
  • Receptor 30 may be any opaque, transparent, or translucent substrate (e.g., metal, plastic, paper, etc.), although it should not be highly absorptive of infrared radiation.
  • the receptor is a thin, flexible film or sheet (e.g., paper, plastic, metal).
  • the receptor is a transparent film, or an embossed plastic film, it is useful as a projection transparency.
  • one surface of receptor 30 may be coated with a conventional primer (e.g., polyamide resin, polyvinyl chloride resin, polyester resin, shellac, cellulose acetate).
  • the image areas on the receptor are water-resistant, smudge-proof, and lightstable.
  • Multi-colored images can also be formed on a single receptor by imaging a plurality of the copying sheets of the invention and successively transferring colored images to the receptor.
  • Blends of colors can also be effected by (l) imaging a first copying sheet in the manner depicted in FIG.
  • a heat-sensitive copying sheet is prepared using a one mil plastic film (e.g., polyester). On one surface of the film a visibly heat-sensitive coating is applied using the following coating composition:
  • composition is knife coated at a wet thickness of 3 mils and dried at about 80 C.
  • a layer having a dry thickness of about 0.5 mil is obtained, which is a coating weight of about 1.3 gm/ft.
  • the resulting copying sheet is imaged by superimposing it over a graphic original and exposing to intense infrared radiation (e.g., in a conventional thermographic copying machine).
  • intense infrared radiation e.g., in a conventional thermographic copying machine.
  • a plastic film having release properties is placed against the heat-fusible layer as a carrier sheet so as to avoid partial transfer of portions of the heatfusible layer to the belt or rollers in the copying machine.
  • the copying sheet After the copying sheet is imaged in the foregoing manner, it is placed against a receptor (e.g., a transparent plastic film) and exposed to infrared radiation whereby the portions of the heat-fusible layer correspond to image areas are softened and become tacky.
  • a receptor e.g., a transparent plastic film
  • the copy sheet is then peeled away from the receptor leaving colored image areas corresponding to the image areas of the graphic original.
  • Sheet material is made having an imageable layer prepared by mixing the following compositions:
  • Composition A Parts Silver behenate l5 Methyl ethyl ketone Tetrachlorophthalic anhydride 0.45 Stannous stearate 0.009
  • Composition B Cellulose propionate resin (PLFS-l 30"
  • composition A is homogenized it is added to composition B and mixed followed by the addition thereto of composition C with further mixing.
  • the resulting composition is knife coated (wet thickness of 3 mils) onto the back side of a one mil plastic film coated with the heat-fusible layer of Example 1. After drying the resulting sheet material is ready for use.
  • An intermediate film member comprising map overlay tracing paper coated according to the technique de scribed in Example 3 of US. Pat. No. 3,094,417 (Workman) is placed against a graphic original and exposed as described in said example.
  • the exposed intermediate film member is then placed against the imageable layer of the sheet material to form a sandwich construction which is then heated at 250 F. until an image of the graphic original is obtained in the imageable layer.
  • the image is formed by reaction between the 4- methoxy-l-naphthol (from the intermediate film member) and the silver soap (in the imageable layer) in the presence of heat.
  • the heat-fusible layer of the imaged sheet is then placed against a receptor and exposed to brief intense infrared radiation in a thermographic copying machine. Upon separating the imaged sheet from the receptor the heat-fusible layer is transferred to the receptor in an imagewise manner.
  • EXAMPLE 3 Sheet material is prepared having an imageable layer comprising dry silver.
  • the dry silver composition is prepared with the following ingredients which are added and mixed in the order given:
