Zusammenfassung:DISCLOSED HEREIN ARE COMPOSITIONS COMPRISING ORGANIC ANHYDRIDES HAVING A REDUCED TENDENCY TO DISCOLOUR WITH TIME, EVEN WHEN HELD AT ELEVATED TEMPERATURES FOR EXTENDED TIMES. THE COMPOSITIONS ARE PRODUCED BY MIXING AT LEAST ONE ACID HALIDE AND VARIOUS DERIVATIVES OF HYDROXY CARBOXYLIC ACIDS WITH AN ANHYDRIDE TO FROM A HOMOGENOUS SOLUTION. ALSO DISCLOSED IS A PROCESS FOR PREPARING THE COMPOSITIONS.
