Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
81 words
An ink-jet recording method comprising the steps of impinging a water-based ink on a recording medium for ink-jet recording, said recording medium comprising an ink-receiving layer containing an ink-receiving polymer and a nonvolatile organic compound having at least one property selected from the group consisting of molecule weight, specific gravity, Young's modulus, conductivity, permittivity and solubility which differs from the ink-receiving polymer, the concentration of said nonvolatile organic compound continuously varying in the direction of a thickness of said ink-receiving layer.
Claim 2
Dependent Claim
81 words
An ink-jet recording method comprising the steps of impinging a water-based ink on a recording medium for ink-jet recording, said recording medium comprising an ink-receiving layer containing an ink-receiving polymer and a nonvolatile organic compound having at least one property selected from the group consisting of molecule weight, specific gravity, Young's modulus, conductivity, permittivity and solubility which differs from the ink-receiving polymer, the concentration of said nonvolatile organic compound continuously varying in the direction of a thickness of said ink-receiving layer.
Claim 3
Dependent Claim
18 words
An ink-jet recording method according to claim 1, wherein said ink-receiving polymer comprises a hydrophilic or water-soluble polymer.
Claim 4
Dependent Claim
56 words
An ink-jet recording method according to claim 1, wherein said nonvolatile organic compound is selected from the group consisting of cellulose derivatives, starch and derivatives thereof, polyvinyl alcohol and derivatives thereof, polyacrylc acid and derivatives thereof, polyester and derivatives thereof, alkyd resin and derivatives thereof, polymethacrylic acid and derivatives thereof, and butyral resin and derivatives thereof.
Claim 5
Dependent Claim
20 words

Claim 8
Dependent Claim
18 words
An ink-jet recording method according to claim 5, wherein said ink-receiving polymer comprises a hydrophilic or water-soluble polymer.
Claim 9
Dependent Claim
56 words
An ink-jet recording method according to claim 5, wherein said non-volatile organic compound is selected from the group consisting of cellulose derivatives, starch and derivatives thereof, polyvinyl alcohol and derivatives thereof, polyacrylic acid and derivatives thereof, polyester and derivatives thereof, alkyd resin and derivatives thereof, polymethacrylic acid and derivatives thereof, and butyral resin and derivatives thereof.
