XLV. The processing of thick photographic emulsions.

Abstract
An attempt has been made to determine satisfactory processing conditions for Ilford G5 electron-sensitive emulsions up to 600 μ in thickness. The penetration and temperature characteristics of metol-hydroquinone, para-aminophenol, and p-diaminophenol developers have been investigated. The observations show that a p-diaminophenol developer gives satisfactory results and a suitable procedure for processing is described. In addition the problems of fixing, washing and drying, have been studied.
