摘要:
A water-based ink for inkjet printers contains at least a water-insoluble colorant, a block copolymer of a polyvinyl ether structure comprising at least one kind of hydrophilic segments and at least one kind of hydrophobic segments, water and an alkali. Each of the hydrophilic segments contains acidic groups. A content of the alkali is such that, when an infrared absorption intensity ascribable to ionic groups to be formed upon addition of an excess amount of the alkali to the block copolymer is supposed to be 100%, an infrared absorption intensity ascribable to ionic groups formed by dissociation of the acidic groups contained in the block copolymer becomes at least 80%, with a proviso that the content does not exceed twice as much as a smallest amount of the alkali that an infrared absorption intensity ascribable to ionic groups to be formed from the block copolymer becomes 100%.

The present invention provides a liquid ejection head, a liquid supply apparatus, a liquid ejection apparatus, and a liquid supply method which enable the channel resistance and pressure loss of liquid in the liquid ejection head to be reduced to increase the speed at which liquid is supplied to the nozzles. To achieve this, an ink supply chamber (44) is placed so as to be laminated on a main ink supply chamber (42). A filter (40) interposed between the main ink supply chamber (42) and the ink supply chamber (44) extends along a surface substantially parallel to a nozzle arrangement plane on which a plurality of nozzles are arranged.

A recording medium is composed of a base material and an ink-receiving layer comprising an alumina hydrate and arranged on at least one side of the base material. When heated at 60°C for 1 hour, the recording medium gives off a lower fatty acid at a concentration in a range of from 0.1 to 1.0 ppm/m>2
摘要:
A water-based inkjet printer ink contains at least a colorant and a resin. The resin is a block copolymer, which contains at least one hydrophilic block and at least one hydrophobic block. Each of the blocks is a vinyl ether polymer. The ink further contains aluminum or an aluminum compound.

An ink-jet recording sheet is composed of a base material and at least one ink-receiving layer arranged on at least one side of the base material. The ink-receiving layer comprises a water-soluble resin and/or a water-dispersible resin as a binder, an inorganic pigment, thiourea or a specific derivative thereof, an acrylamide-diallylamine hydrochloride copolymer and/or a polyallylamine acetate, and a boron compound. The inorganic pigment, the thiourea or specific derivative thereof, the acrylamide-diallylamine hydrochloride copolymer and/or polyallylamine acetate and the boron compound satisfy the following equations (1) and (2): 4 (B + C + D)
摘要:
A printing method and apparatus capable of continuously printing information on a plurality of labels (109) at a correct position without reducing throughput. Upon printing an image on labels (109) stuck on a roll-shaped continuous sheet (108) with a predetermined interval while reciprocally scanning a printhead (100), the printing apparatus receives a raster image command from a host and bitmaps raster data to a data buffer having a capacity capable of storing data for a single scan-printing by the printhead (100), discriminates whether or not raster data to be printed on a plurality of continuous labels can be bitmapped to the data buffer, bitmaps null data for rasters corresponding to a predetermined interval between the labels to the data buffer in accordance with the discrimination result, further discriminates whether or not data for a single scan-printing by the printhead (100) is bitmapped to the data buffer, and prints by scanning the printhead (100) in accordance with the discrimination result.
