Provided are polyamides having a repeating unit represented by the formula
wherein Rand R' are each a lower alkyl group or a cyclic amine residue, and also having a relative viscosity of at least 1.5.
A photosensitive resin composition comprises an addition polymer of a diisocyanate compound and an amide, the amide having a primary and/or secondary amino group at each terminal and containing one or more amide bonds, together with a monomer having a photopolymerizable unsaturated bond and a photopolymerization initiator.
