    Abstract: There is provided a method for producing a stencil for use in screen printing which method comprises coating a screen mesh with liquid photopolymerizable composition, imagewise exposing the coated mesh to radiation to polymerize liquid composition on the mesh in the exposed areas, and removing unexposed liquid composition from the mesh to develop the stencil. Suitably the liquid composition is applied with the screen mesh in contact with a protective film and, after imagewise exposure, the stencil is developed by stripping of the film such that unexposed liquid remains on the film. This provides a simple method of producing a stencil which does not require highly skilled personnel.

    Abstract: A method of manufacturing a water-release transfer is disclosed in which a design in a photopolymerizable ink is applied to a substrate having a water-soluble release coating and the design is subjected to photopolymerizing radiation, e.g. ultra-violet light, to cause the ink to polymerize to a solid state. Preferably the ink comprises a mixture of a liquid unsaturated monomer and a viscous or solid prepolymer, and one or both of the monomer and prepolymer contain acryloyl or methacryloyl groups. The invention includes water-release transfers manufactured using photopolymerizable inks.

    Abstract: Perfeccionamientos en la fabricación de láminas para la transferencia de colorantes en cliente, que comprenden la constitución de una lámina u hoja de soporte flexible portadora de una capa de transferencia de un compuesto polímero que lleva dispersado por lo menos en una zona de su superficie un sólido en forma de partículas no adherentes, cuya capa no es bloqueante a temperatura normal ambiente y fundiéndose a temperatura elevada formando un líquido que tiene una viscosidad que permite la impresión de una superficie situada en contacto con la misma, mientras que dicho sólido en partículas se sublima a dicha temperatura elevada o se funde formando un líquido que como mínimo no aumenta sustancialmente la viscosidad del compuesto polímero fundido.

    Abstract: 852,919. Paper for finger-prints. REED, K. J. July 11, 1958 [July 15, 1957], No. 22348/57. Drawings to Specification. Class 96. [Also in Groups XV and XVI] A finger-print reception sheet e.g. of cast coated paper, has a surface layer containing a chemical reactant, e.g. tannic acid applied in aqueous ethyl alcohol, to form a coloured impression (e.g. of ferric tannate) when e.g. a ferric salt is transferred thereto from an " ink reservoir " pad by the fingers.
