Abstract

253,643. Thornton, J. E. March 31, 1925. Drawings to Specification. Colour photography, screens and screen plates for.-A multicolour screen, applicable to flat or roll films or to glass plates, is built up by cementing together two supports each of which carries different component colour elements of the screen. The sensitive layer may be applied on one side of the built-up screen, and a non-curling colloid layer may, in the case of thin films, be applied on the other side. The components in the case of flexible films are formed upon two thin films; and, in the case of thick films or glass plates, upon a thin film and a thick film or glass plate. The screen patterns may be of line, dot, or other form. It is stated that, in the case of line patterns, the lines on one component support may be parallel to, or may cross at 45<b> or at 90‹, the lines on the other component support. The components are united by applying adhesive to each, superimposing them face-to-face, back-to-back, or face-to-back, and applying heat and pressure.
