Abstract: 1476497 Colour diffusion transfer photographic silver halide film unit FUJI PHOTO FILM CO Ltd 30 Aug 1974 [30 Aug 1973] 38133/74 Heading G2C A colour diffusion transfer photographic film unit comprises (A) a photo-sensitive element comprising a water-impermeable and dimensionally stable support having coated thereon, at least one photo-sensitive silver halide emulsion layer the or each layer having associated therewith a material capable of providing an imagewise distribution of a dye, which dye is soluble in an alkaline processing composition and diffusible in said layer in the presence of said composition, (B) a spreading element, i.e. an element between which and (A) a processing composition may be spread, comprising a water impermeable dimensionally stable transparent support having coated thereon a neutralizing layer containing an acid or acidforming material in an amount necessary for neutralizing an alkaline liquid processing composition spread over the photographic emulsion layer; and (C) a rupturable container so positioned in the film unit that on rupture of the container an alkaline liquid processing composition containing a basic mordant capable of mordanting the dye provided by the dye-providing material is spread between at least one silver halide emulsion layer and the neutralizing layer. The dye-providing material is preferably a dye developer which may have a particle size less than 1 micron. The basic mordant may be a homo- or copolymer of a vinylidene compound having a N-containing heterocyclic ring, or a homo- or copolymer of an acrylic or methacrylic acid derivative having a tertiary amino group, a polymer containing a quaternary N atom. In the Examples the basic mordants are poly-N, N, N-trimethylaminoethyl acrylate hydrochloride and poly-4-vinyl pyridine. The neutralizing layer may be coated with a timing layer. An opacifying agent may be present in a layer of the photo-sensitive element furthest from the surface of intended imagewise exposure, or in the processing composition. The opacifying agent may be present in at least two layers. The film unit may include a light-shielding element and means of applying said element over the photo-sensitive element so that the surface of the film unit to be exposed in a camera can be shielded from light after exposure. The film unit may include a transparent second spreading element, as defined above, located so that the photo-sensitive element is sandwiched between the spreading elements, and a second rupturable container containing a lightshielding composition containing an opacifying agent, the second container being so located that on rupture, the light-shielding composition is spread between the support of the photo-sensitive element and the second spreading element.

The base substrate may be made of paper, wood or plastics material such as phenolformaldehyde sheet, foamed polystyrene, foamed polyester or foamed phenol-formaldehyde resin, and may be planar or formed into a shape such as a dome or sphere. At least one surface is covered with pressure-sensitive adhesive, e.g. uncured rubber or polyisobutylene or polybutadiene rubber, blended with coumarone resins or alkyl-phenol-formaldehyde resins, and further covered with release paper. The yarn may be a thread of natural or synthetic fibre or metal, e.g. lily yarn, gold thread or silver thread. The yarn is preferably applied using an instrument shown in Fig. 5, comprising a guiding pipe 8 having a yarn outlet hole 7. The yarn is inserted with a needle 5 having a thread eye 6, which is threaded with the yarn and then passed through the interior 9 of the guiding pipe and out of the hole 7, the yarn then being removed from the eye 6 and the needle withdrawn.

[Also in Division B8] In a method of producing a package charged with a flowable material, a length of heat sealable tube is heat sealed at one end, is held at the other end while the bottom of bag so formed is blocked out by a gas blast through the open end, is charged with its content and is closed at the other end. A tube formed by folding and longitudinally seaming a web around a mandrel or by direct extrusion from a die is fed intermittently through a cutting device. The tube is gripped by jaws 6, 7 and a bag length is cut off. The tube is then transferred by the jaws to a pair of heater jaws 10 which seal the bottom of the tube. An anvil bar 11 is inserted into the bag and a tool 12 co-operating with the bar punches a weakening line 14 in the bag wall. A pipe 15 is inserted in the open top of the package and a sterilizing or neutral gas, e.g. nitrogen is blown in to distend the bag to block out the bottom, this being assisted by an external plate applied to the underside of the bag. A triangular filling nozzle 20 is then inserted and after removal of the nozzle the bag is closed by heating jaws 22 and finally a tab 23 is adhered over the weakening 14.
