Embodiment Construction

[0034] The present invention will now be described by employing, as an example of a liquid discharge head, an ink jet head (IJ head) that performs recording using ink. However, the liquid discharge head of the present invention may be of a type that can also use various liquids for various surfaces for purposes other than recording. In the present description, ionizing radiation is a general term for radiation that affects the ionization of materials, eg by deep UV light, electrons or X-rays.

[0035] (Explanation of the mechanism of scum generation)

[0036] First, the inventors of the present invention will give an explanation of a new viewpoint related to the mechanism in which scum is generated at the interface between a solid layer formed by using a removable resin and a coating layer formed by using A discharge port forming material for forming ink discharge ports is formed. For this mechanism, the inventors of the present invention postulate that two factors cause scu...

Abstract

According to the present invention, 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, cationic photopolymerization initiator and a 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.

Description

technical field [0001] The present invention relates to a method of manufacturing a liquid discharge head and a liquid discharge head obtained by the method of manufacture. More specifically, the present invention relates to a liquid discharge (jet) recording head that ejects liquid and performs recording, and a liquid discharge (jet) recording head obtained using this manufacturing method. Background technique [0002] Generally, a liquid jet recording head (including an ink jet recording head and an ink jet head) employing a liquid jet recording system (including an ink jet recording system) includes a plurality of minute discharge ports, a plurality of flow paths, and portions along these flow paths Multiple drains available. In order to obtain high-quality images by ejecting ink onto recording paper from the liquid jet recording head, it is preferable to eject the same volume of ink from the respective ejection ports at the same ejection speed. In addition, the shape o...
