Definitions

  • the envelope may include a pod or fluid container filled with processing fluid and a iiuid trapping section spaced from the fluid container and including a highly absorbent pad for receiving excess fluid, the trapping section and envelope being separated by a rupturable seal.
  • a process wherein developing fluid is injected into the envelope from the attached fluid container or by other means and a positive pressure is exerted on the envelope during a soak and development period to assure distribution of the fluid throughout the envelope an maintain the fluid and receiver sheets in spaced relation. At the end of this period the sheets are pressed together to bring them into intimate contact for image transfer. Such action ruptures the seal between the envelope and trapping section so that excess fluid is absorbed by the pad therein.
  • This invention relates to an irnproved process and product for use in image transfer photography.
  • Image transfer photography is well known in the art .and products and apparatus for use with such photography have been commercially available for many years. Where, as is particularly desirable, the processing is to be done within a camera structure, it is essential that the processing materials be so confined or of such nature that they will not contaminate the interior of the camera. Where such process has been used for in-camera processing it has been customary, after exposure of the sensitized sheet or strip of film material, to apply a relatively thick, viscous processing fluid to the sheet adjacent the image area and to spread it across the image area in a uniform layer by progressively sandwiching the sensitized sheet with a sheet of transfer-image receiving material. One of the biggest problems with such materials and process has been in obtaining the desired uniformity of thickness of the viscous processing fluid.
  • any variation in thickness of such layer results in a variation in density in the finished transfer image.
  • any variation in thickness of the layer not only affects the density but also the relative color composition.
  • carneras using such a system have necessarily required the use of parts of relatively high precision.
  • the viscosity of the processing fluid tends to change appreciably with temperature, thereby affecting its spreading properties and tending to make it still more difficult to obtain uniformity of layer thickness under diiferent temperature conditions.
  • even with the viscous uid used it has been practically impossible to avoid some contamination of the processing apparatus used.
  • a further object is to provide such a product and process adapted to use a relatively free-flowing processing uid so confined in the product during the processing 3,352,674 Patented Nov. I4, i967 operation as to prevent contamination of the processing apparatus.
  • the film ⁇ and transferimage-receiving sheets or ⁇ strips are either secured together around the edges of their image areas or are adapted to be held sealed together during processing so as to effectively form a fluid-tight envelope.
  • free-flowing processing liquid is injected into this envelope in sufficient quantities ⁇ and under such pressure as to positively hold the opposed walls, which carry the image areas, spaced materially apart from one another throughout a predetermined soak period.
  • the image areas are pressed together into intimate face-to-face relationship so that all excess liquid is forced from therebetween and are held in this relationship until image transfer has been completed.
  • the sandwich incorporates a fluid trapping section which includes a pad of highly absorbent material isolated from the image areas during the soaking period and into which the excess fluid is forced when the image areas are pressed together for image transfer.
  • FIG. 1 is a plan view of an image transfer film sandwich construction embodying my invention
  • FIG. 2 is a longitudinal section through the sandwich of FIG. l;
  • FIGS. 3, 4, and 5 illustrate successive steps involved in using the sandwich of FIG. 1 in accordance with my improved process
  • FIGS. 6 and 7 illustrate a slightly modified method of practicing my improved process
  • FIG. 8 illustrates an alternative form of film product in accordance with my invention
  • FIG. 9 is a longitudinal section through the sandwich of FIG. 8;
  • FIG. l0 illustrates one stage during the processing of a sandwich of the type shown in FIG. 8;
  • FIG. 1l illustrates another form of sandwich construction as well as the manner of processing this form
  • FIG. 12 illustrates a slightly modified method of processing a sandwich construction of the type shown in FIG. 11;
  • FIG. 13 shows a form of processing apparatus especially useful in practicing the improved process in accordance with my invention.
  • FIG. 14 is a -somewhat diagrammatic sectional view through a camera adapted for use with the materials and processing method in accordance with my invention.
  • FIG. 1 and 4 An image transfer product in accordance with my invention is shown in FIG. 1 and 4comprises a sandwich 1 formed by superimposed sheets 2, 3 which are sealed together around their periphery as cliagrammatically indicated by the X--hatched areas 4, 5, 6, and 7, in FIG. 1, whereby they form a fluid-tight envelope. Extending transversely across the sandwich near one end is an additional seal indicated at S adapted to isolate the image portion 9 of the sandwich from a trapping portion 1t) located at one end thereof. Seal 8 is made considerably weaker than seals d to 7, so that it will rupture when a predetermined uid pressure has .been built up within the image portion of the envelope.
  • Seal 8 may be formed in a manner similar to the rupturable seal on the pods of viscous processing fluid such as are commonly employed in commercially available image transfer products and which are described, for example, in U.S. Patent 2,543,181. At least those portions of the inner faces of sheets 2 and 3 which are outlined by the dash-dot line 11 in FIG. 1 constitute the useful image areas of the sheets, one of which is photosensitive and the other of which is adapted to receive an image lby transfer when processed in conjunction with the photosensitive area in the presence of an appropriate processing fluid.
  • sheet 2 While either sheet could carry the .photosensitive image area, I have shown sheet 2 as carrying the photosensitive image area designated 12, and sheet 3 as carrying the transfer-image-receptive area 13..In order to permit exposure of the photosensitive area at least one of the sheets must also be transparent to actinic rays. Again, for illustrative purposes, it is assumed that photosensitive sheet 2 is transparent and receiving sheet 3 is opaque.
  • the fluid-trapping portion of the sandwich includes a pad 14 of highly absorbent material, such as blotting paper, cloth7 gauze, or the like, which, as briefly explained above, will tend to rapidly absorb and hold the excess processing fluid.
  • a pad 14 of highly absorbent material such as blotting paper, cloth7 gauze, or the like, which, as briefly explained above, will tend to rapidly absorb and hold the excess processing fluid.
  • a porous pad 18 of loosely woven fibers, inert to the processing fluid is provided between the sheets adjacent the seal 4.
  • Pad 1S serves to hold the sheets 2 and 3 spaced slightly apart in this injection area and therefore affords a location easily recognizable by the user to indicate to him where the tip of the syringe should be inserted.
  • Preferably during manufacture as much air as is practical is expelled from between sheets 2 and 3 so that, prior to use, they will, as shown in FIG. 2, lie in intimate face-to-face contact with one another throughout their entire area except, of course, in those areas carrying pads 14 and 18.
  • the photosensitive image area 12 is first exposed in a suitable camera or the like so as to produce a latent image therein. Thereafter, either in a darkroom or a dark chamber such as the interior of the camera, a predetermined quantity of free-flowing processing fluid is injected into the interior of the sandwich.
  • a predetermined quantity of free-flowing processing fluid is injected into the interior of the sandwich.
  • processing may be performed in a darkroom while the sandwich is supported on a suitable supporting member 20, the end portion 21 of which is preferably formed so as to support the injection area adjacent pad 18 raised slightly above the level of the image portion 9.
  • the tip 17 of syringe 16 is pushed through the sheet 3 and into the pad 18 ⁇ and the syringefis then actuated to force its liquid processing composition through the pad and between ⁇ the image areas 12 and 13.
  • the image areas 12 and 13 must be held spaced apart from one another throughout their extent for at least a predetermined soaking period and, in order to accomplish this result, when the syringe has been emptied, it is pulled out from the sandwich and pressure is applied to the outside of the envelope so as to build up an internal pressure within the fluid 15 throughout the interior of the ima-ge portion of the envelope.
  • This may be conveniently performed with the aid of a suitable squeegee roller 22 which, as illustrated ⁇ in FIG.
  • the processing begins and is carried out in accordance with any one of many well known diffusion transfer process techniques.
  • An example of a silver salt diffusion transfer process which can be used is disclosed in U.S. Patent No. 2,352,014 to Rott.
  • development of the exposed silver halide takes place 4during a soaking period when the process fluid is present, as between the two sheets of the present invention.
  • squeegee roller 22 across the surface of sheet 3 will then press the latter into intimate face-to-face contact with sheet 2 throughout the entire image area and forces all excess processing fluid into the absorbent pad 14 of trap 10.
  • FIGS. 6 and 7 illustrate the practice of my invention utilizing a backing member 25 for this purpose.
  • This backing member 25 is shown as being provided with a pair of lateral supporting ribs 26 and 27 which are adapted to rest on the edge portions of the sandwich as illustrated in FIG. 7 to hold the back ⁇ ing surface 28 thereof at the desired spacing above support 20.
  • sheet 3 will be held by backing surface 28 at the desired spacing from sheet 2.
  • Backing member 25 may be either ⁇ positively held down or, as illustrated, may be made of sufficient weight that it will remain in position under the slight pressure used during the soaking period.
  • member 25 At the end of the soaking interval, member 25 will be lifted out of the way and the process will continue as described above, roller 22 being rolled across the sandwich to rupture the seal 8, press the image areas together, and force the excess fluid into the absorbent pad 14.
  • FIG. ⁇ 8 illustrates a somewhat modified form of sandwich construction which incorporates the processingk fluid in compartment or chamber-31 forming part of the sandwich itself.
  • This pod or chamber 31 is preferably at the opposite end of the sandwich from the fluid trapping ⁇ chamber 32.
  • a pressure-rupturable seal 33 isolating the processing fluid contents 34 from the central portion 37 bearing the image areas 35 and 36. Seal 33 is adapted to rupture when a predetermined pressure is built up in the fluid 34, so that the fluid may be injected between the image areas 35 and 36 from the container 31.
  • edges of the sandwich are sealed together as diagrammatically indicated at 38, 3g, 40 and 41, these edge seals being appreciably stronger than the rupturable seal 33, as well as the rupturable seal 42 separating trap 32 from the image portion 37 of the sandwich.
  • This sandwich construction also illustrates another slight modiiication in that the upper and lower sheets of the sandwich are each built up from several sheet sections secured together in end-to-end relationship. This permits the use, in each portion of the sandwich, of materials which are best adapted for the particular function of that portion.
  • the composite upper sheet is formed by a left-hand end portion 43 which forms the upper wall of the fiuid containing chamber 31 and which is secured as at 44 to the left-hand end of a sheet 45 of transfer-image-receptive material. The latter is in turn secured at its right-hand end as at 46 to another strip of sheet material 47 which serves as the upper wall of the Huid trapping section 32.
  • the composite bottom sheet is formed of a left-hand section 48 forming the bottom of the Huid container 31 and secured as at 49 to a transparent sheet of photosensitive material 5i).
  • the opposite end of sheet 5G is in turn secured at 51 to a piece of sheet material 52 forming the bottom wall of the fluid trapping portion 32.
  • FIG. l() illustrates one way of accomplishing my improved process using a sandwich construction of the type shown in FIGS. 8 and 9.
  • the sandwich is suitably supported in a darkroom or in a dark chamber such as the interior of a camera, and pressure is built up within the iiuid 34 in container 31 suicient to rupture seal 33 and to inject the uid between the photosensitive and transfer image areas 35 and 36 of sheets 50 and 45 and to maintain the desired low positive pressure therebetween for the duration of the soaking period.
  • this operation is performed while sheet 45 is backed up by means of a backing member 25 so as to limit the tendency of the sheets 59 and 45 to bulge outwardly.
  • the desired pressures may conveniently be built up and maintained -by rolling a squeegee roller 22 from the left end of the sandwich across the container portion 31 to a position as shown in FIG. 10.
  • Sheets 45 and Sil are held apart from one another by the pressure within the vad until the end of the soaking period, at which time member 25 is moved out of the way and squeegee roller 22 is once again moved toward the right across the sandwich, to cause rupture of seal 42 and to force the remaining excess fluid into the trap 32. As before this will also bring the transfer-receptive image area 36 of receiving sheet 45 into intimate faceto-face contact with the photosensitive image area 35 of sheet 5t) so as to permit image transfer to obtain.
  • FIGS. 11 and 12 show sandwiches which may otherwise be similar to those described above but in which the rupturable seal 8 or 42 is lacking. Instead, prior to injection of the iluid into the image portion of the sandwich, the upper and lower sheets are firmly pressed together into fluid-tight relationship along a line extending across the sandwich near the trapping section and held in this condition throughout the soaking period.
  • FIG. 13 An apparatus using this type of construction, and which is especially adapted for practicing my im proved process, is illustrated in FIG. 13.
