Photogenerated Amines and Diamines: Novel Curing Systems for Thin Film Coatings

Abstract

The photogeneration of organic amines from alpha-dimethyl-3,5- dimethoxybenzyl carbamates is described. The photoactive carbamates are prepared easily through reactions involving the Li catalyzed addition of isocyanates to alpha-dimethyl-3,5-dimethoxybenyl alcohol or through the use of active ester chemistry. A variety of active carbamates that can be used to generate primary and secondary amines as well as diamines has been tested successfully. Free amines are liberated upon exposure of the carbamates to UV radiation below 300 nm. Preliminary tests indicate that photoactive carbamates incorporating onitrobenzyl groups are also readily obtainable from isocyanates.
