Abstract

1359086 Epoxy resin compositions CIBAGEIGY AG 5 April 1972 [6 April 1971] 15611/72 Heading C3B [Also in Division G2] The following epoxy resin compositions are used in photographic materials (see Division G2) (1) A mixture of epoxy resin I epoxy resin II and an adduct of II with less than a stoichiometric amount df a polyester formed from adipic acid and neopectyl glycol and an acid curing agent formed by reacting glutaric anhydride with glycerol to give a polyester with an acid number of 142. (2) A mixture of epoxy resins I and II with the above curing agent. Other cycloaliphatic epoxy resins may replace the ones specified above. Typical photoactive constituents are ammonium and potassium ferrioxalate.
