Abstract

1,199,326. Panchromatic emulsions. AGFA GEVAERT A.G. Aug.14, 1967 [Aug. 29, 1966], No.37221/67. Heading G2C. A panchromatically sensitized emulsion or emulsion mixture which has a low gradation in at least one region of the spectrum (blue, green, red) is brought to uniform gradation by adding at least one other emulsion which has the same optical sensitivity as said one region but a higher gradation.
