Abstract:
A liquid discharge head for recording by discharging recording liquid, said liquid discharge head comprising:a surface formed at least on a part of an inner face of said liquid discharging head, the inner face being in contact with the recording liquid, wherein a polymer is applied to said surface, the polymer comprising: (1) a first portion having a lyophilic group for lyophilic processing, and (2) a second portion having a group with substantially the same, or the same, interfacial energy as a surface energy of said surface, but different from an interfacial eneregy of the lyophilic group, wherein the second portion of the polymer is oriented toward said surface, and the first portion of the polymer is orientated away from said surface, and wherein the polymer is subdivided with a catalyst for a polymeric cleavage prior to being applied to said surface by binding the subdivided polymers.
