Liquid jet printing head and liquid jet printing apparatus provided with said liquid jet printing head

Ink jet head and ink jet apparatus provided with said ink jet head

An ink jet recording head wherein at least peripheral portions of discharge ports comprise a film which contains a polymer having a fluorine heterocyclic structure in the principal chain.

Manufacturing method for ink jet recording head and ink jet recording

A method for manufacturing an ink jet head comprises a process to prepare a substrate where ink discharging energy generating elements are arranged; a process to provide a solid layer on the aforesaid substrate for the formation of liquid passages corresponding to the foregoing energy generating elements and at the same time, to provide a solid layer for the formation of a liquid chamber; a process to cover the substrate having the aforesaid solid layers with a resin; and a process to remove the aforesaid solid layers. The thickness of the aforesaid resin layer covering the upper part of at least a portion of the aforesaid solid layer for the formation of the ink passages on the side which is different from the side where the solid layer for the formation of a liquid chamber exists is made thinner than the thickness of the aforesaid resin layer covering the upper part of the solid layer for the formation of the liquid chamber, hence providing a highly reliable ink jet head having an excellent property suitable for cutting process required for obtaining the discharging port portion precisely and accurately as well as a secure adhesion between the resin and the substrate.

Method for manufacturing ink jet head, ink jet head manufactured by such

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.

Ink jet head and ink jet apparatus employing the same

A method of manufacturing a recording head for use in an ink jet head involves providing a discharge port formation member having a surface in which orifices are to be formed, treating a discharge port face of the discharge port formation member with a water-repellent material, and forming orifices by applying radiation from a pulsed laser beam to the discharge port formation member which has been treated by the material having a water-repellent property, so that forming the orifices creates byproducts. The method also involves sticking at least once a tape having an adhesive layer against the discharge port face of the discharge port formation member against at least peripheral portions of the orifices having the byproducts created in the orifice forming step sticking thereto and deposited therein, and peeling the tape therefrom.

Method for manufacturing ink jet recording head having water-repellent

An ink jet recording head having a fluid passage constituted by forming, on a substrate, an outer frame made of a hardened resin obtained by transfer molding, wherein a transfer-molding resin composition which is the material of the hardened resin is composed of an epoxy resin, a hardening agent, an agent for enhancing hardening and a filler, and the content of the filler is ranged from 0.5 to 17.0 wt. %.

Transfer-molding resin composition for use to manufacture ink jet

An ink jet head 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 on an ink discharge port forming surface of the ink jet head. 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.

Ink jet head having an improved ink discharge surface and ink jet

A method of manufacturing a recording head for use in an ink jet printer involves the steps of, after treating a surface of a discharge port formation member having plural discharge ports formed thereon, which formation member is formed with a material having a water-repellent property, forming the discharge ports by applying radiation from a pulsed laser beam, and then performing heat treatment for eliminating byproducts from the orifice forming sticking to and deposited in peripheries of the discharge ports, or if an orifice plate, byproducts sticking to peripheries of the discharge ports.

A recording medium comprising a substrate and a non-porous ink receiving layer is provided. The ink receiving layer contains a water-insoluble polymer containing a cationic resin. The recording medium may be employed for recording by attaching droplets of a recording liquid thereon.

Recording medium with non-porous ink-receiving layer and method of use

A recording device comprises a plural number of ink jet device units, each unit comprising an ink jet head portion, its drive controlling portion and a wiring portion, juxtaposed on a common base plate.

Recording device

Recording medium with non-porous ink-receiving layer

There are disclosed an ink-receiving composite polymer material wherein a nonvolatile organic compound is caused to penetrate into and diffuse through an ink-receiving polymer forming, from any one surface side thereof, and a recording medium for ink-jet recording wherein a nonvolatile organic compound is caused to penetrate into and diffuse through an ink-receiving layer, from the surface thereof.

Ink-receiving composite polymer material

A recording medium comprises an ink receiving layer provided on a substrate, wherein said ink receiving layer contains a cationically modified product of polyvinyl alcohol and a water soluble polymer having no active hydrogen.

Recording medium

A print protecting member comprising a transfer layer laminated peelably on a substrate is provided in which the transfer layer comprises at least a surface layer and an under layer. The surface layer has a lower softening point than that of the under layer.

Print protecting member transfer layer having surface layer with lower
