ON LATENT IMAGE FADING IN ILFORD K.0 AND K.2 EMULSIONS

Abstract

Fading in Ilford K.0 and K.2 emulsions was investigated at 20 degrees C and -20 degrees C. Track segments with rates of energy loss from 0.6 to 1.8 Mev/micron were used. K.0 and K.2 emulsions stored for 30 days at -20 degrees C showed no evidence of fading. After a 30-day fading period, K.2 emulsion stored at 20 degrees C and at 50 percent relative humidity showed less than 10 percent fading. K.0 emulsion stored at 20 degrees C and at 50 percent relative humidity showed severe fading. This is illustrated by curves of grain density versus residual range for 2-, 6-, 13-, and 30-day fading periods.
