Gradation-variable black and white paper |
| abstract |
A variable-grade SW paper with only one silver halide emulsion layer, in which the sensitization is avoided, is mixed with a mixture of at least two light-sensitive silver halide emulsions, one of which has its absorption maximum in the range from 480 to 580 nm and the other below 480 nm. a compound of the formula contains what X represents the remaining members of an optionally benzo- or naphtho-condensed heterocycle which may contain further substituents. |
