Abstract

Abstract Disclosed herein is a recording medium comprising a base material and an ink-receiving layer provided on the base material, wherein the ink-receiving layer comprises a high-water-absorptive material obtained by grafting, on a water-absorptive polymer, an inorganic oxide formed from an inorganic alkoxide represented by the formula (R₂) n -M-(OR₁) m-n wherein M denotes an element selected from the group consisting of Si, Al, Ti, Zr, Ca, Fe, V, Sn, Be, B and P, m is a valence of M, n is an integer of 1 or 2, R₁ denotes an alkyl group having 1 to 4 carbon atoms which may have a substituent group, and R₂ denotes an alkyl group having 1 to 4 carbon atoms or a phenyl group, each of which may have a substituent group.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 125 words
A recording medium comprising a base material and an ink-receiving layer provided on the base material, wherein the ink-receiving layer comprises a high-water-absorptive material obtained by grafting, on a water-absorptive polymer, an inorganic oxide formed from an inorganic alkoxide represented by the formula (R₂) n -M-(OR₁) m-n wherein M denotes an element selected from the group consisting of Si, Al, Ti, Zr, Ca, Fe, V, Sn, Be, B and P, m is a valence of M, n is an integer of 1 or 2, R₁ denotes an alkyl group having 1 to 4 carbon atoms which may have a substituent group, and R₂ denotes an alkyl group having 1 to 4 carbon atoms or a phenyl group, each of which may have a substituent group.
Claim 2
Dependent Claim 116 words
A recording medium comprising a base material and an ink-receiving layer provided on the base material, wherein the ink-receiving layer comprises a high-water-absorptive material obtained by grafting, on a water-absorptive polymer, at least two inorganic oxides formed from inorganic alkoxides represented by the formula (R₂) n -M-(OR₁) m-n wherein M denotes an element selected from the group consisting of Si, Al, Ti, Zr, Ca, Fe, V, Sn, Li, Be, B and P, m is a valence of M, n is an integer of 0, 1 or 2, R₁ denotes an alkyl group which may have a substituent group, and R₂ denotes an alkyl group or a phenyl group, each of which may have a substituent group.
Claim 3
Dependent Claim 27 words
The recording medium according to Claim 1 or 2, wherein the water-absorptive polymer comprises at least a polyacrylic acid and a neutralized salt of the polyacrylic acid.
Claim 4
Dependent Claim 29 words
The recording medium according to Claim 3, wherein the neutralized salt of the polyacrylic acid is a salt with at least one of lithium, sodium, potassium and amine compounds.
Claim 5
Dependent Claim 22 words
The recording medium according to Claim 1 or 2, wherein the linear transmittance of the recording medium is at least 10 %.
Claim 6
Dependent Claim 22 words
The recording medium according to Claim 1 or 2, wherein the surface gloss of the recording medium is at least 30 %.
Claim 7
Dependent Claim 39 words
A method of forming images, which comprises applying droplets of an ink from an orifice to the ink-receiving layer of the recording medium according to Claim 1 or 2 in accordance with a recording signal, thereby conducting image formation.
Claim 8
Dependent Claim 24 words
A method of producing a print, which comprises applying an ink to the recording medium according to Claim 1 or 2, thereby conducting printing.
Claim 9
Dependent Claim 20 words
A print obtained by printing images on the ink-receiving layer of the recording medium according to Claim 1 or 2.
