Abstract

Improving tolerance of X-ray films to safe lights. An organic thioether is added to the emulsion using 2% molar soln. at 60 degrees C which can dissolve twice as much silver chloride as will dissolve in water at 60 degrees C. Preferably, the thioether includes the group -OCH2CH2-S-5 - 50 mg. of thioether per mole silver may be added during the maturation of the silver halide. In an example 1,10-di-thia-4,7,13,16-tetraoxa-cyclooctadecane is used.
