Abstract
Novel triisocyanato triazines and carbamoyl triazine derivatives thereof are disclosed. These compounds will self-cure and also function as crosslinkers for compounds containing active hydrogen groups. When the active hydrogen-containing compounds are hydroxylated polymers, environmentally-resistant coatings are provided.
