Abstract

571,106. Photographic stencils. KODAK, Ltd., and BLABER, M. P. W. Jan. 31, 1944, No. 1794. [Class 98 (ii)] An abrasively-etched image is formed on a surface by first forming on the surface a photographic stencil of the desired image, applying to the stencil, but not to the base areas, a layer of rubber, and then abrasively etching. The stencil may be first formed on another support and transferred to the surface to be etched before or after the further layer is applied thereto. The surface to be etched may be first coated with the rubber layer and then after producing thereon or applying thereto the stencil, the underlayer is removed where not protected by the stencil. The stencil may be applied to a curved surface to be etched. A gelatine stencil may be soaked in a solution of a substance coagulating rubber latex (e.g. aluminium sulphate), excess solution wiped off, the stencil dried, and then bathed in liquid rubber latex. The layer may be rendered tacky by adding emulsified mineral oil to the latex or by treating the coagulated layer with a swelling agent. In example 1, a stencil is formed on a glass plate coated with a process-type gelatinosilver halide emulsion by exposure, development, and etch-bleaching with an acid cupric halide hydrogen peroxide bath. The stencil is washed, dried, and soaked in saturated aqueous aluminium sulphate solution, excess solution blotted off, the stencil dried and then bathed in rubber latex and rinsed in water, and then finally dried. The rubber layer may be applied from a roller. Where the surface to be etched is curved, the exposure or one or more of the processing steps may be performed before transfer. The stencil may also be formed by tanning development and other processes. Specification 554,300 is referred to.
