Photographischer Träger mit reflektierender Schicht.

摘要

A support, such as plastics film, e.g. p.e.t., has one surface made matt, e.g. by incorporating or coating thereon a pigment or by sand blasting, to a thickness preferably of 15-30 mu m; a metal layer, e.g. of Te, Mb, Po, Co, Zn, Cu, Ni, Fe, Sn, V, Ge, Ag, Cr, Ti or an alloy thereof, preferably of Al, is coated on the matt surface, e.g. by vacuum deposition (in which case a resin primer is first coated), to a thickness of 20-4000 ANGSTROM ; the centre plane average roughness of the resultant matt surface of the metal layer which has a secondary diffuse-reflectivity is 0.1-1.2 mu m. On the metal layer is coated an adhesive layer, e.g. of a synthetic polymer, 0.1-10 mu m thick, and on the photographic reflective support are coated the layers to make a photographic light-sensitive material. The support provides good luminance and saturation of the image formed.
