Abstract
1,267,391. Photographic colour separation material. AGFA-GEVAERT AG. March 19, 1969 [March 25, 1968], No.14344/69. Heading G2C. Photographic material for producing colour separation records produces the same gamma value when exposed to light of the 3 primary colours L 1 , L 2 and L 3 ; the material comprises 2 panchromatic silver halide emulsions A and B, the differences in threshold sensitivities between the emulsions for each colour being such that when the 2 characteristic curves of the emulsions A and B are summed they produce substantially the same rectilinear characteristic curve for each primary colour. The emulsions may be mixed in one layer, one may be coated on one another, or they may be coated on opposite sides of a transparent support.
