Abstract

463,110. Sound - records ; photo - mechanical printing - surfaces. CZEIJA, 0., and LIERG, F. Sept. 17, 1395, No. 25765. Convention date, Sept. 22, 1934. [Class 98 (ii)] Sound-record strips which may also bear picture records are produced by printing from a forme consisting of a long flexible strip having a printing surface of basic character with a fatty printing colour of acid character. The printing forme may be prepared by copying the record on a silver halide emulsion layer, and bleaching the developed layer with an agent containing an alkali, e.g. ammonia or borax, printing being carried out with a fatty dye ground with acidic varnish. Alternatively, a differentially hardened layer is treated with a solution of tannic acid followed by a mixture of alum and glycerine whereby basic aluminium tannate is formed in the layer. Celluloid or paper may be used as the printing base, and the forme may be employed for offset printing. The Specification as open to inspection under Sect. 91 describes also the use of strips of zinc, aluminium, or of their alloys, or of flexible material having a coating of these metals, the surface of which is prepared by anodic formation. This subject-matter does not appear in the Specification as accepted.
