An ink tank having an ink storing portion encases an ink-absorbent member for holding ink. The ink-absorbent member comprises a porous material having therein compressed open cells. The compression ratio r.sub.1 of an apparent volume V.sub.1 before compression to an apparent volume V.sub.2 after compression (r.sub.1 =V.sub.1 /V.sub.2) and the cell number p represented by number of cells per inch in the state of V.sub.1 satisfy the relation (I) below, and p being not more than 60.100 [inch.sup.-1 ].ltoreq.r.sub.1 .multidot.p.ltoreq.200 [inch.sup.-1 ](I)
摘要:
Disclosed herein is an image-transfer medium for ink-jet recording, comprising a base material, and a releasing layer and a transfer layer provided on the base material, wherein the transfer layer has fine particles of a thermoplastic resin, a thermoplastic resin binder, a cationic resin and inorganic fine particles, and the total content of the cationic resin and the inorganic fine particles falls within a range of from 3% to 20% by weight based on the total weight of the fine particles of the thermoplastic resin and the thermoplastic resin binder.
摘要:
Disclosed herein is a transfer medium for ink-jet recording adapted to form an image on a transfer layer thereof and then heat the transfer layer from the side of a support of the transfer medium to transfer the transfer layer to a transfer-printing medium, wherein an index is provided on the support.
摘要:
Disclosed herein is a printing medium, comprising a base material and an ink-receiving layer provided on at least one side of the base material, wherein the ink-receiving layer comprises, in combination as essential components, a hydrophilic resin and a cationic compound comprising both structural units of the formulae (I) and (II) ##STR1## wherein R1, R2, R4 and R5 are independently hydrogen or an alkyl group having 1 to 3 carbon atoms, R3 is a phenyl, naphthyl, benzyl or phenethyl group, R6 is an alkyl group the main chain of which has 10 to 30 carbon atoms, and X.sup.- is a halide ion selected from the group consisting of chloride, bromide and iodide ions, a sulfate ion, an alkylsulfate ion selected from the group consisting of methylsulfate and ethylsulfate ions, an alkyl- or arylsulfonate ion, or an acetate ion, and the cationic compound is used in combination in a proportion of 1 to 40 parts by weight per 100 parts by weight of the hydrophilic resin.
摘要:
Disclosed herein is an image-transfer medium for ink-jet printing, comprising a base material, and a releasing layer and a transfer layer, both, provided on the base material, wherein the transfer layer comprises fine particles of a water-insoluble thermoplastic resin, a water-insoluble thermoplastic resin binder and a crosslinking agent coated with a thermoplastic resin.
摘要:
An ink container for containing ink to be supplied to an ink jet head, includes fibrous material; an ink discharge port for discharging the ink to the ink jet head; a portion for containing the fibrous material at least adjacent the ink discharge port; wherein the fibrous material is deformed within a degree of elasticity, forming a plurality of intersections in different directions, and contained in the containing portion.
摘要:
An ink filling method for filling an ink cartridge with ink to be supplied to a recording head for ejecting ink includes providing an ink cartridge having a negative pressure producing material accommodating portion and an ink accommodating portion, the negative pressure producing material accommodating portion accommodating a negative pressure producing material and being provided with an air vent, and the ink accommodating portion being substantially hermetically sealed except for fluid communication with the negative pressure producing material accommodating portion, and accommodating directly the ink to be supplied to the recording head, the ink cartridge further includes a partition wall between the negative pressure producing material accommodating portion and the ink accommodating portion, the partition wall being provided with a gap for permitting formation of meniscus of the ink; and directly injecting the ink into the ink accommodating portion.
