Abstract

501,661. Sensitive material for colour photography. INTERCHEMICAL CORPORATION. Sept. I, 1937, No. 23931. Convention date, Jan. 21. Drawings to' Specification. [Class 98 (ii)] A corrected colour component record comprises a support bearing a developed negative image recording one component of the light from the object and a registering developed positive image of lower contrast recording a different component of the light. The positive image may be produced on material capable of giving a positive image direct or by reversal of an originally formed negative image. The layers may be sensitized to red and green light respectively and an intermediate layer of plain gelatin which may contain a screening dye may be arranged between them. Alternatively,' the support may be dyed. Specification 440,086 is referred to.
