reference example 1

[0098] First, a fluorine-containing resin-containing liquid obtained by dissolving a fluorine-containing resin in a fluorine-containing solvent was prepared. As the fluorine-containing resin, Cytop (registered trademark) A type manufactured by Asahi Glass Co., Ltd. was used.

[0099] Next, the fluorine-containing resin-containing liquid was applied to the surface of the nozzle plate base material by a spin coating method, and the coating film was subjected to heat treatment. The heat treatment temperature is 180° C., and the heat treatment time is 30 minutes. A polyimide film was used as the base material of the nozzle plate.

[0100] In this way, a nozzle plate comprising a lyophobic film comprising a compound having a ring structure is obtained. The film thickness of the lyophobic film was 200 nm.

Embodiment 1

[0102] Using the nozzle plate obtained by the method of Reference Example 1 above, the inkjet head 1 was manufactured by the above method. In the reheating treatment, the heating temperature was 205° C., and the heating time was 2 hours. The cooling treatment was performed at a rate of 1.5°C / min until reaching 40°C.

[0103] In this way, an inkjet head including a liquid-repellent film comprising a compound in which a part of the ring structure is ring-opened is obtained.

Abstract

Disclosed are an ink jet head and an ink jet printer. Provided is an inkjet head having excellent liquid repellence. According to an embodiment, an inkjet head is provided. The inkjet head includes anozzle plate and a liquid repellent film. The nozzle plate is provided with nozzles. The nozzles eject ink onto a recording medium. The liquid repellent film comprises a compound. The compound contains a repeating unit containing a cyclic structure. One part of the cyclic structure is an open loop.

Description

technical field [0001] Embodiments of the present invention relate to an inkjet head and an inkjet printer. Background technique [0002] There is known an inkjet head structure in which ink is pressurized by a piezoelectric member or the like to eject ink droplets from nozzles. In an inkjet head having such a structure, ink repellency may be imparted so that ink does not adhere to the surface of the nozzle plate. As a method for imparting ink repellency, there may be mentioned forming an ink repellent film containing a fluorine-containing resin on the surface of the nozzle plate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an inkjet head excellent in liquid repellency and an inkjet printer equipped with such an inkjet head. [0004] According to an embodiment, an inkjet head is provided. The inkjet head includes a nozzle plate and a lyophobic film. The nozzle plate is provided with nozzles. The nozzles ...
