The present invention relates to a secondary amine which is manufactured from a cheap marketing material, being stabilized at room temperature, and having reactivity with an electrophile. The secondary amine is manufactured by additionally reacting one or more kinds of amines to one or more kinds of maleate (amid/ester) and fumarate (amid/ester) Michael acceptors. The amine can be used as a co-reactant with aliphatic polyisocyanate for polyurea coating.
