Abstract
Disclosed is a novel triamine derivative, particularly a ketimine or aldimine derivative derived from a triamine and a ketone or an aldehyde, which has the following general formula: ##STR1## [wherein ##STR2## X is hydrogen or a hydrocarbon radical of 1 to 8 carbon atoms; Y is a hydrocarbon radical of 1 to 8 carbon atoms; X and Y, together with their neighboring carbon atom, may form a 5- to 7-membered aliphatic hydrocarbon ring; and n is an integer of 1, 2 or 3]. This novel triamine derivation is useful as a curing agent for epoxy resins or polyurethane resins.
