Abstract

The hardening test of gelatin with 2,4-dichloro-6-hydroxy-1,3,5-triazine mono sodium salt was studied at pH 5, 7, 8 and about increasing temperature, respectively. The hardener was prepared by the reaction of cyanuric chloride with sodium hydroxide, disodium hydrogenphosphate-12-water and trisodium phosphate-12-water in the presence of water. The product was identified by elemental analyzer. IR spectrophotometer. Novel hardener can be used in photographic emulsion and showed very good hardening effect.
