Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a blocked aliph. isocyanate compd. improved in the capability of being deblocked at a low temp. by using lysine aminoethyl ester triisocyanate as the aliph. triisocyanate compd. to be blocked. SOLUTION: This blocked isocyanate compd. is represented by the formula (wherein R , R , and R are each independently a residue of an active hydrogen compd.), is prepd. by using lysine aminoethyl ester triisocyanate as the aliph. triisocyanate compd. to be blocked, and is deblocked to regenerate isocyanate groups at a temp. lower than that required in deblockng other blocked isocyanate compds. which are prepd. by blockng other isocyanate compds., such as hexamethylene diisocyanate, isophorone diisocyanate, and polyisocyanurate compds. prepd. from these isocyanate compds., with the same blockng agent as the one used in preparing the blocked isocyanate compd. of the invention. Examples of the active hydrogen compd. used as the blocking agent are alcohols, phenols, thiols, amides, amines, imines, imides, ureas and oximes.
