摘要:
An ink-jet recording head has ejection outlets formed by treating a face of a plate for the ejection outlets with a water-repellent and irradiating the plate with a laser beam from the backside of the plate. The head is provided with a sealing member for sealing the ejection outlets. The water-repellent has a hardness of higher than the pencil hardness 6B at room temperature. A decomposition product layer is formed on the layer of the water repellent at peripheral portions of the ejection outlets.

The invention provides a composite composition comprising a cationically polymerizable organic resin, a cationic photoinitiator, a hydrolysate and/or condensate of at least one hydrolysable silane compound and inorganic nanoparticles. The composite composition is suitable for the preparation of patterned moulded articles or substrates having a patterned coating, in particular by photolithography. Micropatterns obtained show improved properties, such as a high shape stability and an excellent elastic modulus.

The invention provides a wiper blade member maintaining a high water repellency even for a pigment ink, and an ink jet recording apparatus equipped with such wiper blade member. The wiper blade member of the invention for eliminating a deposition an ink discharge face of the ink jet recording head is made water repellent by a condensate of a fluorine-containing hydrolysable compound. The condensate increases a fluorine content significant and shows a strong adhesion a substrate (blade) by the presence of the hydrolysable group. It strongly adhered to the substrate by a condensation reaction only by a hydrolysis, but the adhesion can be further improved by a photo- or thermocuring. The curing reaction can be executed at a relatively low temperature, without causing a damage to the blade constituting the substrate.
