Abstract
Official abstract text for this publication.
A liquid ejection head includes a member having a liquid ejection port, wherein a surface of the member on which the ejection port is open is formed by a curing reaction of a siloxane compound having a first group and a second group. The first group has a fluorine atom. The second group has at least one selected from the group consisting of a hydroxy group, a carboxy group, a carbonyl group, and a polyether structure.
First claim
