Filed: 1964-04-28
Abstract: 1,068,565. Pictures. FABRIKA FOTORABOT. April 28, 1964, No. 17510/64. Heading B6X. A method of producing a decorative print comprises the steps of sticking the emulsion side of a basic print, produced by a photographic process, to the emulsion side of a mask on a transparent film and having an opaque portion and a transparent or translucent portion so that at least a portion of the print can be seen through the mask, the emulsion sides being stuck together by a gelatine glue in such a manner that no air is trapped therebetween. The basic print is a colour print or a black and white print, which is painted and retouched by acidic aniline paints, which are fixed by steeping in a 3% solution of acetic acid. The mask is prepared by drawing an outline of a picture frame on a white paper in black indian ink and reproduced photographically on a film. A retouched opaque portion is printed by a projection method in the central part of the film. Alternately, the opaque portion may be printed separately on a flat film and the latter can then be glued to the base of the film referred to above. The negative thus produced can be printed on a unilateral positive film with a transparent base. The basic print and mask are then cemented together by hot gelatine glue applied to the emulsion sides, which have been degreased by wiping them lightly with alcohol and rolled by a rubber roller so as to exclude any air trapped therebetween. When the join is thoroughly dry the basic print and mask are cut out in the shape of the blank shown in the Figure and the flaps 4 are bent along lines 1 and 3, the blank is adhesively mounted on a support by means of the flaps 4. To provide a small convexity the decorative print and the support are clamped along the flaps 4 in a clamping frame. The surface of the decorative print is finished by washing with water containing a polishing medium and polishing with soft wadding until a high lustre gloss is obtained.

IPC: C08G73/04
Filed: 1956-06-08
Abstract: Cation-exchange resins or adsorbents with a selective affinity for copper ions are made by reacting (a) a polyethylene imine or a phenylene diamine with (b) formaldehyde or epichlorhydrin and with (c) acrylic acid or acrylonitrile.  The reaction may be carried out in various orders, the amine normally being used in a solution of acid, e.g. HCl; but a preferred method is to react (a) with a quantity of (b) insufficient to form a gel, then to react this product with (c), and finally to add a further quantity of (b) to complete the reaction.  When acrylonitrile is used, the final product may be hydrolysed in an aqueous or alcoholic, alkaline or acid solution to convert the nitrile groups into carboxyl groups.  For ion-exchange purposes, the resin is dried at 60 DEG  C., disintegrated and swelled in solvent, e.g. water. Several examples are given of various combinations of reagents and orders of reaction; the preferred phenylene diamine is meta phenylene diamine.
