Definitions

  • the layer of processing composition between the frame and the area may be formed, for example, by advancing the sheets between a pair of pressure-applying members. In the presence of this layerof processing composition, a latent image in the frame is developedto silver and a soluble silver complex from unexposed silver halide is formed, is transferred by imbibition to the area, and there is developed to silver to produce a positive image.
  • an image-receiving area of the aforementioned type aredefined, in practice, by an openingin a masking sheet which is superposed on the imagereceptive sheet.
  • the masking sheet by preventing the layer of processing composition from contacting portionsof the image-receptive sheet. surrounding the area, provides. a clean white border for apositive image formed in the area.

  • image-receiving areas 28 constitute as large a proportion of image-receptive sheet 20 as possible
  • the width of openings 36 is almost as great as the width of image-receptive sheet 20.
  • masking sheet 34 is greater in width than image-receptive sheet 20 and overlaps its edges.
  • Masking sheet 34 and image-receptive sheet .20 are joined by a strippable bond which permits them to be readily separated.
  • a suitable strippable bond for example, is produced by coating adjacent surfaces of sheets 20 and 34 with relatively incompatible plastic materials and sealing the resulting laminations together by means of heat and/or pressure.
  • Suitable incompatible plastic materials are a plastic composition comprising zein which preferably is applied to masking sheet 34 and a plastic composition comprising ethyl cellulose which preferably is applied to image-receptive sheet 20. Details of such a bond are more fully described in Patent No. 2,563,387, issued on August 7, 1951, to William J. McCune, In, for Photographic Image-Receiving Sheet.
  • a succession of containers, designated at 38 in the illustrated embodiment, are provided for carrying liquid processing composition.
  • containers 38 are aflixed to masking sheet 34 in alignment with residual sections 30 by such means as adhesive strips 40, one container being associated with one image-receiving section 26.
  • Each container is adapted to eject its contents through a rupturable mouth 42 for spreading between the frame 16 arid the image-receiving area 28 with which it is assocrate structed from a blank of three-ply sheet material having a single fold.
  • the outer ply serves as a backing or support and is composed of a thin, relatively inexpensive, tough material, preferably a paper such as kraft paper.
  • intermediate ply is composed of a substantially vapor-, J
  • the inner ply is composed of a suitable thermoplastic or thermosetting plastic material, for example a polyvinyl acetal such as polyvinyl butyral or polyvinyl formal, which protects the container contents from contamination.
  • a suitable thermoplastic or thermosetting plastic material for example a polyvinyl acetal such as polyvinyl butyral or polyvinyl formal, which protects the container contents from contamination.
  • a composition comprising by weight approximately 60% to 70% polyvinyl butyral, approximately 10% to 23% nitrocellulose and approximately dibutyl sebacate is particularly satisfactory.
  • the two folds of the inner ply are sealed to each other as by the application of heat and pressure.
  • a strip of adhesive which is so constituted that the adhesive forces between the strip and the inner ply are less than the cohesive forces between end portions of the inner ply which are sealed together.
  • a satisfactory strip may be composed, for example, of ethyl cellulose or of a mixture of ethyl cellulose and parafiin, the mixture including at least 50% by weight of ethyl cellulose. Since the bonding forces between those sections defining the mouth are less than the bonding forces between other sections of the container, the application of opposed compressional forces to the container causes discharge of the containers contents through its mouth.

  • a developer such as hydroquinone
  • a silver halide solvent such as sodium thiosulphate
  • an alkali a viscosity-increasing, film-forming material
  • Suitable plastic materials for increasing the viscosity of the liquid compositions for example, are the water-soluble cellulosic materials such as hydroxyethyl cellulose, carboxymethyl cellulose, and carboxy-methyl-hydroxyethyl cellulose.
  • photosensitive sheet and assemblage 18 are superposed with masking sheet 34 interposed between them and with a frame 16 in registration with an opening 36.
  • a container 38 when opposed compressional forces are applied to it by pressure-applying means on opposite sides of sheets 10 and 20, is capable of discharging its contents through its mouth 42. Relative motion between the pressure-applying means and sheets 10 and now causes spreading of the processing composition in a thin layer between frame 16 and image-receiving area 28. This layer is capable of developing a latent image in fparne 16 and of forming a positive print in imagereceiving area 28.
  • the pressure-applying means are shown as a pair of rollers 44 and 46 between which photosensitive sheet 10 and assemblage 18 may be advanced in superposed relation.
  • Roller 44 is provided with a pair of shouldered end portions 48, one of which is shown in Fig. 2, and an intermediate pressure-applying surface 50.

  • Each residual section is further provided with transverse, straight-line perforations 56 extending from each of its edges toward its tear-out hole. Tear-out holes 54 and straight-line perforations 56 are designed to enable their associated image-receiving sections 26 to be readily detached from the residual sections 30 which adjoin them.
  • Fig. 1 the approximate path traced by the processing composition following its release from a container 38 and spreading from one of the opposite edges of an imagereceiving area 28 toward and beyond the other is shown in dotted lines at 58.
  • the layer of processing composition which has an initial width slightly less than the width of image-receiving area 28, expands toward the opposite edges of masking sheet 34. That portion of the layer that lies between the frame 16 and image-receiving area 28 is of a predetermined thickness as above indicated.
  • Masking sheet 34 by overlapping the opposite edges of image-receiving section 26, prevents the layer from contacting them.

  • Container 38 is provided with a quantity of processing composition in excess of the absolute minimum required for covering merely an image-receiving area 28 with a layer of predetermined depth in order to enable complete covering of image-receiving area 28 notwithstanding adverse conditions of temperature and humidity and maldistribution of processing composition 39 as a result of non-uniform rupture of the mouth and nonuniform spreading.
