, (2008/06/13)
A diamine compound represented by general formula (I): STR1 wherein R is as defined in the specification a group of formula (II) STR2 where R1 and R2 as defined in the specification or a group of formula (III) STR3 where R1 and R2 have the same meanings as defined above, and Z is as defined in the specification, or --SO2 --. 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 Ar1, which are as defined in the specification R3 is a group of general formula (VI) below: STR6 where R has the same meaning as defined above; R4 is as defined in the specification and m and n are each zero or a positive integer which satisfy m≥2n.
