A transfer sheet comprises a support, and a transfer layer separable from the support and receivable an ink, wherein the transfer layer contains a hot-melt adhesive particle. The hot-melt adhesive particle in the transfer sheet comprises a particle having a melting point of more than 80&deg; C. (A) and a particle having a melting point of not more than 80&deg; C. (B), and the particle (A) comprises a hot-melt adhesive particle having an oil absorption of not less than 50 ml/100 g (A1) and a hot-melt adhesive particle having an oil absorption of less than 50 ml/100 g (A2). Further, the transfer layer may comprise a film-formable resin component and a dye fixing agent. The transfer sheet is excellent in stability on delivery of a sheet, so prevents the inside of the printer from staining, and excels in ink-absorption to a degree that the stain transfer does not occur.

Transfer sheets

A cleaning sheet comprises a sheet-shaped base and an adhesive layer formed on at least one surface of the sheet-shaped base member. The adhesive layer has an adhesive strength in the range of 0.1-0.5 gf according to a 180-degree peel-off method provided by JIS Z-0237. Or the adhesive layer has a tackiness degree in the range of 1-5 according to a J DOW method provided by JIS Z-0237.

Cleaning sheet and recording medium set including the same cleaning sheet

A recording medium and a recording method are provided which can realize an image having excellent storage stability. An ink composition comprising a colorant of at least one dye selected from the group consisting of a stilbene azo dye, a triphenylmethane dye, and a xanthene dye is used, and the recording medium having a recording layer comprising silica and a binder, wherein the binder comprises a polymer component, 5 to 55% by weight of a polymer component of the binder is a styrene/butadiene latex, and 20 to 45% by weight of the styrene/butadiene latex is derived from a butadiene monomer.

Recording medium and ink jet recording method

An ink jet recording method which can realize a sharp image and ink dots having excellent circularity is disclosed. The ink jet recording method comprises the step of ejecting ink droplets of an ink composition onto a recording medium to form an ink image on the recording medium, the ink composition having a contact angle with a sized recording paper of 0.degree., as measured one sec after the initiation of contact of the ink composition with the sized recording paper, and containing not less than 60% by weight of water, the recording medium having an ink-repellent layer comprising a water-soluble silicone compound and/or a water-soluble fluorine compound.

Ink jet recording method

A cleaning sheet comprises a sheet-shaped base and an adhesive layer formed on at least one surface of the sheet-shaped base member. The adhesive layer has an adhesive strength in the range of 0.1-0.5 gf 125 mm according to a 180-degree peel-off method provided by JIS Z-0237. Or the adhesive layer has a tackiness degree in the range of 1-5 according to a J DOW method provided by JIS Z-0237.

A recording medium and a recording method are provided which, in a printer comprising a recording head for performing recording without contact with a recording medium and means for changing the carrying direction of the recording medium, can effectively prevent contact of a recording medium with a recording head. The recording medium comprises: a recording sheet; an adhesive layer provided on one side of the recording sheet; and a release sheet provided on the adhesive layer, the recording medium having a Gurley stiffness of 200 to 1500 mgf, the adhesive layer comprising a crosslinked acrylic polymer, the recording medium being such that, in a holding power test according to JIS-Z-0237, the time taken for causing a test piece of the recording medium to drop from an adherend is 500 min or more, or when the time taken for causing a test piece of the recording medium to drop from an adherend is less than 500 min, the test piece drops as a result of coming off at the interface between the adherend and the adhesive layer.

Recording medium with adhesive layer

An ink jet recording medium is disclosed, comprising a base having provided on one side thereof a recording layer having an ink receiving layer whose surface is smoother than plain paper's and on the other side thereof a coating layer comprising an aqueous binder containing 10 to 40% by weight of a higher fatty acid salt to a coating weight of 0.1 to 0.3 g/m.sup.2. An ink jet recording medium is also disclosed, comprising a base having provided on only one side thereof a recording layer, said recording layer having a coefficient of dynamic friction of 0.65 to 0.75 in mutual friction, the back surface of said base having a coefficient of dynamic friction of 0.15 to 0.25 in mutual friction, and the coefficient of static friction between said recording layer and said back surface is 0.55 to 0.65. The ink jet recording medium is prevented from being double-fed and can be transferred at improved precision, thereby providing high quality images. The ink jet recording layer is freed from feed trouble and can be transferred at improved precision, thereby providing images of high resolving power.

Ink jet recording medium

An ink jet recording method which can simply realize a plurality of resolutions in a single printer without varying the amount of ink per droplet is disclosed. An ink jet recording method comprises the steps of: selecting a recording medium; changing an image resolution depending on the selected recording medium; and ejecting ink droplets onto the recording medium to form ink dots thereon, wherein the amount of ink of the droplet is constant when the resolution is changed, and wherein the image resolution is changed so that ink penetrability or ink repellency of the recording medium makes the diameters of the ink dots on the recording medium fall in the range of from 100 to 160% of diagonal dot pitch of the resolution.

Ink jet recording method and apparatus providing a plurality of image

An ink jet recording method includes the steps of: (a) holding a sheet-like recording medium having a glossy surface in which the 60-degree mirror glossiness defined in JIS Z8741 is 60% or more between a driving roller disposed on a back surface side of the sheet-like recording medium and a notched roller having a thickness in a range of 0.05 to 0.5 mm, and pressing the glossy surface with a pressing force in a range of 5 to 30 g against the driving roller; (b) carrying the sheet-like recording medium; and (c) ejecting ink onto the glossy surface so that an image is recorded by dots of the ink on the glossy surface.

An ink jet recording film is provided which has well-balanced properties required of the ink jet recording film. The ink jet recording film comprises a transparent substrate, an anchor coat layer laminated on one side of the substrate, and an ink-receptive layer laminated on the anchor coat layer; wherein the ink-receptive layer comprises a polyvinyl alcohol having a degree of saponification of 80 to 95% and a degree of polymerization of 1,000 to 2,000.
