A diamine compound represented by general formula (I): ##STR1## wherein R is as defined in the specification a group of formula (II) ##STR2## where R.sup.1 and R.sup.2 as defined in the specification or a group of formula (III) ##STR3## where R.sup.1 and R.sup.2 have the same meanings as defined above, and Z is as defined in the specification, or --SO.sub.2 --. The diamine compound is produced by reducing a dinitro compound of general formula (IV) ##STR4## wherein R has the same meaning as defined above. Imidation of the diamine compound with a tetracarboxylic acid dianhydride produces a polyamideimide resin having a repeating unit represented by general formula (V): ##STR5## wherein Ar and Ar.sup.1, which are as defined in the specification R.sup.3 is a group of general formula (VI) below: ##STR6## where R has the same meaning as defined above; R.sup.4 is as defined in the specification and m and n are each zero or a positive integer which satisfy m.gtoreq.2n.
