摘要:
A method for manufacturing a liquid discharge head includes the steps of depositing a solid layer for forming a flow path on a substrate on which an energy generating element is arranged to generate energy that is used to discharge liquid, forming, on the substrate where the solid layer is mounted, a coating layer for coating the solid layer, forming a discharge port used to discharge a liquid, through a photolithographic process, in the coating layer formed on the solid layer, and removing the solid layer to form a flow path that communicates with the energy element and the discharge port, whereby a material used for the coating layer contains a cationically polymerizable chemical compound, a cationic photopolymerization initiator and an inhibitor of cationic photopolymerization, and whereby a material of the solid layer that forms a boundary with a portion where the discharge port of the coating layer is formed contains a copolymer of methacrylic anhydride and methacrylate ester.

The present invention discloses a method of producing a liquid flow path shape capable of refilling ink at a high speed by optimizing a three-dimensional shape of the liquid flow path and suppressing the vibration of a meniscus and a head thereof. According to the invention, a pattern to form the liquid flow path to be formed on a substrate with a heater is formed by a positive photosensitive material in a two-layered structure of upper and lower layers, and the lower layer is used for forming the liquid flow path after being thermally crosslinked.

The present invention provides a method for manufacturing a high quality ink jet head, and an ink jet head manufactured by such a method, in which, in a case where a coating resin layer constituting ink flow path walls is formed, even when a solvent having a strong dissolving force is used, it is not feared that a configuration of an ink flow path pattern is distorted. In the method, a photosensitive resin composition layer in which an inter-molecule bridging reaction proceeds by irradiation of an ionization radiant ray having a first wavelength band and a molecule decaying reaction of main chain decomposing type of the resin proceeds by irradiation of an ionization radiant ray having a second wavelength band different from the first wavelength band is formed on a substrate on which energy generating elements were provided. Thereafter, an ink flow path pattern is formed by the irradiation of the ionization radiant ray having the first wavelength band and a developing process. Then, a coating resin layer constituting ink flow path walls is formed on the ink flow path pattern. After ink discharge ports are formed, the photosensitive resin composition layer forming the ink flow path pattern is dissolved and removed by irradiating the ionization radiant ray having the second wavelength band.
