More Information
Summary:A method for producing a liquid ejection head including an ejection surface having a cured product of a negative photosensitive resin composition includes the steps of applying the negative photosensitive resin composition to form a coating film, subjecting the coating film to exposure, and after the step of subjecting the coating film to exposure, performing heating at 120° C. or higher, in which the negative photosensitive resin composition contains a polymer (A) containing a unit originating from an epoxy group-containing acrylic ester and at least one selected from a unit originating from acrylic acid and a unit originating from an acrylic ester capable of being deprotected at 120° C. or higher.
