摘要:
An ink jet recording apparatus includes a detachable ink cartridge for storage of the ink to be supplied to a recording head. A joint of an ink supply line in the ink jet recording apparatus to be coupled with an ink outlet portion of the ink cartridge for delivering the ink is loosely fitted to be slidable in a direction crosswise to an axis of the supply line toward a coupling position with the ink outlet portion.
摘要:
An ink comprises a recording agent and a liquid medium capable of dissolving or dispersing the recording agent, wherein said ink contains a compound represented by the following Formula (I): ##STR1## wherein R.sub.1 and R.sub.2 each represent a group selected from a hydrogen atom, an alkyl group, a hydroxyl group and a carboxyl group; and R.sub.3 represents a monohydric hydroxyalkyl group. The ink is suitably used for ink-jet recording.
摘要:
A method for producing an ink jet recording head comprising the following steps, a step which forms the photosensitive water-repellent processing layer in the ink discharge port face, a step which irradiates light onto the water-repellent forming region and hydrophilic forming region in the water-repellent processing layer, to cure the layer, a step which irradiates light selectively onto the hydrophilic forming region to reduce water repellency of the water-repellent processing layer and to impart hydrophilicity to the hydrophilic forming region, and a step which forms an opening, which constitutes part of the ink discharge port, in the water-repellent processing layer.
摘要:
An ink jet head, characterized by having a sealing member formed of a composition comprising a solvent-free one-component silicone-modified epoxy resin in the liquid state at room temperature as a principal component, said composition containing, other than said silicone-modified epoxy resin, a latent hardener, wherein said silicone-modified epoxy resin comprises a silicone component in an amount of 10 to 60 parts by weight versus 100 parts by weight of a starting epoxy resin. And ink jet apparatus which is provided with said ink jet head and a recovery means for said ink jet head. The ink jet head always performs stable ink discharging to provide a high quality print.
摘要:
An ink jet head comprises parts for holding liquid ink, the parts being sealed with a moisture-curing sealant composed mainly of an organic high polymer compound having an alkoxysilane moiety represented by Formula (1) in the molecule thereof: ##STR1## where X is hydrogen, methyl, ethyl, propyl or halogen; R is methyl, ethyl or propyl; and n is 1, 2 or 3.
摘要:
An ink-jet recording process and apparatus employing ink that includes a recording agent and a liquid medium capable of dissolving or dispersing the recording agent, wherein said ink contains both a compound represented by the following Formula (I) and a compound represented by the following Formula (II): ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each represent an alkyl group or a hydroxyalkyl group, and any one of them may represent a hydrogen atom; X.sup.- represents an inorganic acid ion; R.sub.4 and R.sub.5 each represent a group selected from a hydrogen atom, an alkyl group and a hydroxyalkyl group; and R.sub.6 represents a group selected from a carboxyl group, a hydroxyl group, a sulfone group, an alkyl group and a hydrogen atom. The ink is suitably used in the ink-jet recording.
摘要:
A process for producing an ink jet head comprising a liquid-discharge energy generating element for discharging a liquid, a discharge opening, a liquid-flow path, and a substrate for holding the liquid-discharge energy generating element, the process comprises the steps of: preparing the substrate; providing on the substrate the liquid-discharge energy generating element; providing a solid layer with a convex shape on the surface of the substrate where the liquid-discharge energy generating element has been provided and at the part where the liquid-flow path and the discharge opening are to be provided, the solid layer being formed of a resin capable of being dissolved away; applying on the substrate provided with the solid layer a curable material in a thickness larger than the thickness of the solid layer, to cover the solid layer; curing the curable material; evenly removing the cured material until the convex portion of the solid layer is laid bare; and dissolving away the solid layer to form the liquid-flow path and the discharge opening.
