20140311661 | PROCESS FOR PRODUCING A LIQUID EJECTION HEAD - A process for producing a liquid ejection head having a substrate and an ejection orifice forming member having an ejection orifice for ejecting liquid, including forming, on the substrate, a photocationically polymerizable resin layer which includes a photocationically polymerizable resin material and becomes the ejection orifice forming member; laminating, on the uncured photocationically polymerizable resin layer, a layer containing a condensation product of a hydrolyzable silane compound having a cationically polymerizable epoxy group and a hydrolyzable silane compound having a fluorine-containing group; laminating a water-repellent layer including a hydrolyzable silane compound having a perfluoropolyether group on the condensation-product-containing layer; subjecting the photocationically polymerizable resin layer, condensation-product-containing layer, and water-repellent layer to pattern exposure; collectively curing exposed portions of the photocationically polymerizable resin layer, condensation-product-containing layer, and water-repellent layer; and removing non-exposed portions of the photocationically polymerizable resin layer, condensation-product-containing layer, and water-repellent layer to form the ejection orifice. | 10-23-2014 |
20150062249 | LIQUID DISCHARGE HEAD AND METHOD OF PRODUCING THE SAME - Provided is a liquid discharge head comprising a discharge port-forming member having discharge ports for discharging a liquid and having a surface provided with a liquid-repellent film. The liquid-repellent film includes a layer containing a resin composition containing at least one of polyurethane and polyrotaxane disposed on the discharge port-forming member and a layer containing a fluorine compound and having a thickness of 10 nm or less disposed on the resin composition-containing layer. When a scratch-forming tool, a diamond tip having a tip diameter of 15 μm, is pressed onto the liquid-repellent film with a load of 0.098 N (10 gf) and is reciprocated ten times, the depth of a scratch formed on the surface of the liquid-repellent film is smaller than the thickness of the fluorine compound-containing layer. | 03-05-2015 |
