Abstract
A photosensitive resin composition usable in forming an ink-jet recording head, and a production method of the head. The composition comprises a polyetheramide resin having a repeating unit represented by the following formula (1), a compound that generates an acid by light irradiation, and a crosslinking agent for the polyetheramide resin which acts under acidic conditions. The composition improves adhesion between a substrate and an ink flow path forming member which constitute the ink-jet recording head
