Patent

CA 1340429

New nucleophilic urethanes are described and claimed, which are the reaction product of a monoisocyanate, a diisocyanate or a polyisocyanate with a basic alkoxylated amine whose hydroxyl functionality has been adjusted to a value of 0.5 to 2 by etherification, esterification and/or reaction with a monoisocyanate. These compounds are particularly used, individually or as a mixture, as neutralizing nucleophilic compositions in desensitizing inks for the printing by dry or humid offset, typographic, or flexoqraphic methods, destined to locally neutralize the electrophilic layer of a chemical pressure sensitive copying set. The disclosed compounds have a better neutralizing power which allows to reduce the weight per surface unit of the desensitizing printing by at least a third.
