Abstract:
A method for manufacturing a liquid ejection head includes selectively exposing a first photosensitive resin layer to light, thereby curing the portion of the first photosensitive resin layer defining a flow channel member; forming a second photosensitive resin layer on the first photosensitive resin layer; selectively exposing the second photosensitive resin layer to light, thereby curing the portion of the second photosensitive resin layer defining an ejection opening member; and removing the unexposed portions of the first and the second photosensitive resin layer at one time with a developer. Before removal with the developer, the water absorption W of the intermediate layer, the water absorption W 1  of the exposed portion of the first photosensitive resin layer, and the water absorption W 2  of the exposed portion of the second photosensitive resin layer satisfy the relationship W≥W 1 >W 2.

Claim (Index 1):
A method for manufacturing a liquid ejection head including a substrate, a flow channel member overlying the substrate and defining a flow channel through which a liquid flows, an ejection opening member overlying the flow channel member and defining an ejection opening through which the liquid is ejected, and an intermediate layer between the substrate and the flow channel member, the method comprising:\n forming the intermediate layer over the substrate; forming a first photosensitive resin layer over the intermediate layer; selectively exposing the first photosensitive resin layer to light, thereby curing the portion of the first photosensitive resin layer defining the flow channel member; forming a second photosensitive resin layer over the first photosensitive resin layer; selectively exposing the second photosensitive resin layer to light, thereby curing the portion of the second photosensitive resin layer defining the ejection opening member; and removing the unexposed portions of the first and the second photosensitive resin layer at one time with a developer; wherein before the removing with the developer, water absorption W of intermediate layer, water absorption W 1  of the exposed portion of the first photosensitive resin layer, and water absorption W 2  of the exposed portion of the second photosensitive resin layer satisfy the relationship: W\u2265W 1 >W 2 .
