Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the subject new diamine capable of providing a photosensitive polyimide high in sensitivity, excellent in solubility in solvents, by introducing a propargyl group as a cationically polymerizable photosensitive group. SOLUTION: This diamine is shown by formula I (R is a group of formula II, O-CH2 -C≡CH, O-CH2 CH2 -O-CH=CH2 , etc.) such as 4,4'-diamino-3,3' dipropinoxycarboxydiphenylmethane. The compound is obtained, for example, by esterifying or etherifying 4,4'-diamino-3,3'dicarboxydiphenylmethane with a halogenated propargyl such as propargyl bromide in an organic solvent such as N,Ndimethylacetamide at 0-80 deg.C for 3-48 hours without admixture of water.
