摘要:
A recording medium comprises basic magnesium carbonate and a magnesium salt of silicic acid or of phosphorus oxy-acid. Ink-jet recording is conducted using the recording medium to obtain high image density without any problem such as indoor discoloration, white haze, fattening of letters, etc.
摘要:
A recording medium which comprises a support and an ink receiving layer containing pigments provided on the support, the pigment having a BET specific surface area of 30 to 120 m.sup.2 /g and an iodine adsorbability per unit surface area of 1.5 mg/m.sup.2 or more as the main pigment component.
摘要:
A recording medium for ink-jet recording has an ink-receiving layer comprising spherical basic magnesium carbonate, amorphous magnesium carbonate or a mixture of aluminum oxide and basic magnesium carbonate. The recording medium promises a good storage stability of recorded images, i.e. less deterioration due to indoor color changes, together with a high image density.
摘要:
A recording medium having an ink-receiving layer containing a pigment and being formed on a support. The pigment is composed mainly of a pigment component having a specific surface area within the range of from 30 to 150 m.sup.2 /g and an oil absorption value within the range of 2.0 to 5.0 cc/g; and the recording medium has a roughness index K.gamma. (m1/m.sup.2) and an absorption coefficient K.alpha. (m.multidot.sec.sup.-1/2) according to the Bristow test, respectively within the ranges of 10.ltoreq.K.gamma..ltoreq.30, and 5.0.times.10.sup.-6 .ltoreq.K.alpha. .ltoreq.3.5.times.10.sup.-5. A method of color ink jet recording by application of droplets of a recording liquid onto the recording medium.

摘要:
A recording medium having at least a pigment and a binder on the surface of a base, wherein the binder is comprised of at least water-soluble polyester. An ink jet recording method includes the step of performing recording on a recording medium by discharging ink from an orifice of an ink jet recording head in accordance with recording signals, wherein the recording medium has at least a pigment and a binder on the surface of a base, and wherein the binder is comprised of at least water-soluble polyester. The amount of the water-soluble polyester is 40% or more with respect to the total weight of the binder.

摘要:
Provided is a recording method for image formation on a recording medium by application thereon of an ink containing a water-soluble dye having an anionic group or a cationic group in the molecule: the recording medium comprising a substance having an ionic group counter to the anionic or cationic group of the water-soluble dye and having molecular weight of not higher than 1,000, and a polymeric substance having molecular weight of not lower than 2,000.
摘要:
Disclosed is a method for ink jet recording that has the steps of providing a stack of sheets which has a cleaning paper interspersed in each twenty to five hundred recording sheets in the stack, feeding the sheets from the stack to an ink jet recording unit, and printing with an ink jet printing unit on the fed sheet. The recording sheets are made of a coated layer that contains pigment formed on a base material and the cleaning paper has a Bekk smoothness of less than 40 seconds and a surface adhesion strength ranging from 1 to 500 gf as defined by JIS-Z-0237 and determined by a 90.degree. peel method.
摘要:
A recording medium contains, within an ink absorbent substrate per se or in an ink receiving coat layer formed on a substrate, basic magnesium carbonate together with a cationic surfactant and/or a nonionic surfactant. The recording medium is suitably used for color ink jet recording of the both-ways serial printing type and eliminates substantially the tone difference between forward and backward printings and the discoloration during indoor storage.
