Abstract:
1. A method for manufacturing an inkjet recording head having a substrate, a member provided with an ejection port for ejecting ink formed on the substrate, and a water repellent layer formed on the member, the method comprising: forming a photo-cationic polymerizable resin layer containing a photo-cationic polymerizable resin material on the substrate; performing pattern exposure of the photo-cationic polymerizable resin layer to form a latent image of a fine pattern including the ejection port; forming the water repellent layer containing a water repellent material capable of forming a bond in reaction with the photo-cationic polymerizable resin material on the photo-cationic polymerizable resin layer on which the latent image is formed; developing the photo-cationic polymerizable resin layer to thereby remove a non-exposed portion of the photo-cationic polymerizable resin layer and remove a water repellent layer portion corresponding to the non-exposed portion to thereby form the fine pattern; and curing the photo-cationic polymerizable resin layer by heat treatment to form a member provided with the fine pattern and promote a reaction of the photo-cationic polymerizable resin material and the water repellent material.
