Disclosed is a photosensitive composition which contains an alkali developable resin, a polymerizable compound, a photopolymerization initiator, and a thermal crosslinking agent. The alkali developable resin is a polyurethane resin that is linked by urethane groups. The polyurethane resin has at least one carboxyl group at an end of the main chain, while having an ethylenically unsaturated group in a side chain.
