摘要:
A method for manufacturing an ink jet head, which is provided with discharging ports, ink passes conductively connected to the discharging ports, and energy generating elements for generating energy to be utilized for discharging . ink, comprises the processes of giving hydrophilic property to the side of the discharging port formation plane of a work piece for constructing the discharging ports, forming an intermediate layer having a coupling agent containing Si on the plane to which the hydrophilic property is given, and forming a water repellence layer on the upper layer of the intermediate layer. Then, after machining the discharging ports by irradiating a pulse laser onto the plane of the discharging port formation member having the water repellence layer, the hydrophilic by-product generated in the vicinity of the discharging ports when the discharging ports are machined is removed to recover the water repellency around the discharging ports, thereby to enable the prevention of the adhesion of ink thereto. Hence preventing the degradation of the printing quality.

An adhesive sheet-type sealing member (1) is suitably used for protecting ink-ejecting nozzles (30) or a communication hole of an ink-jet recording head (12) during transportation or storage. The sealing member (1) exhibits a yield point at a load of not more than 1 kgf/cm for a specimen of 10 mm wide at a stress rate of 200 mm/min ±10% according to JIS-K-7113 and/or exhibits a folding load of not more than 0.10 g/cm for a specimen of 10 mm wide with a free length of 10 mm from the end of a specimen holder measured on the center of an electronic balance placed at a position 5 mm apart from the end of the specimen holder.
摘要:
An ink-jet recording head has ejection outlets (4) formed by treating a face of a plate for the ejection outlets with a water-repellent (3) and irradiating the plate with a laser beam from the backside of the face having been treated with the water-repellent, and it is provided with a sealing member (5) for sealing the ejection outlets. The water-repellent has a hardness of higher than the pencil hardness 6B at room temperature. A second layer is formed on the layer of the water repellent in peripheral portions of the ejection outlets.
摘要:
An ink jet head (120) accomplishes high quality recording for a long term by an improved liquid repellency treatment. This liquid repellency treatment is applied to at least a peripheral portion of a discharge port (14) on an ink discharge port forming surface of the ink jet head (120). A mixture of a fluorine-containing high polymer compound and a compound having fluorine substituted hydrocarbon group and a silazane group, alkoxysilane group or halogenized silane group is employed as a liquid repellent agent.
