Abstract

Abstract A waterproofing method for an ink jet record in a method of recording images on a recording sheet by an ink jet recording method using aqueous ink, comprising forming or applying, on at least the imaged portion of the recording sheet after forming images thereon, a compound represented by the formula M.sup.I M.sup.III (XO.sub.4).sub.2.12H.sub.2 O wherein M I represents a mono-valent metal atom or an ammonium group, M III represents a tri-valent metal atom, and X represents a sulfur atom or a selenium atom.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 82 words
A waterproofing method for an ink jet record in a method of recording images on a recording sheet by an ink jet recording method using aqueous ink, comprising applying on at least the imaged portion of the recording sheet after forming images thereon, a compound represented by the formula M.sup.I M.sup.III (XO.sub.4).sub.2.12H.sub.2 O wherein M I represents a mono-valent metal atom or an ammonium group, M III represents a tri-valent metal atom, and X represents a sulfur atom or a selenium atom.
Claim 2
Dependent Claim 82 words
A waterproofing method for an ink jet record in a method of recording images on a recording sheet by an ink jet recording method using aqueous ink, comprising applying on at least the imaged portion of the recording sheet after forming images thereon, a compound represented by the formula M.sup.I M.sup.III (XO.sub.4).sub.2.12H.sub.2 O wherein M I represents a mono-valent metal atom or an ammonium group, M III represents a tri-valent metal atom, and X represents a sulfur atom or a selenium atom.
Claim 3
Dependent Claim 32 words
A waterproofing method for an ink jet record as in claim 1, wherein said compound is applied to the whole surface of the recording sheet after forming the ink jet record thereon.
Claim 4
Dependent Claim 43 words
A waterproofing method for an ink jet record as in claim 1, wherein said compound is applied onto the ink jet record formed on the recording sheet through a nozzle of the same ink jet printer used for forming the ink jet record.
Claim 5
Dependent Claim 48 words
A waterproofing method as in claim 1, 2, or 3, wherein M I is selected from the group consisting of sodium, potassium, rubidium, cesium and thallium, and M III is selected from the group consisting of aluminum, gallium, indium, titanium, vanadium, chromium, manganese, iron, cobalt, iridium and rhodium.
Claim 6
Dependent Claim 82 words
A waterproofing method for an ink jet record in a method of recording images on a recording sheet by an ink jet recording method using aqueous ink, comprising forming on at least the imaged portion of the recording sheet after forming images thereon, a compound represented by the formula M.sup.I M.sup.III (XO.sub.4).sub.2.12H.sub.2 O wherein M I represents a mono-valent metal atom or an ammonium group, M III represents a tri-valent metal atom, and X represents a sulfur atom or a selenium atom.
Claim 7
Dependent Claim 82 words
A waterproofing method for an ink jet record in a method of recording images on a recording sheet by an ink jet recording method using aqueous ink, comprising forming on at least the imaged portion of the recording sheet after forming images thereon, a compound represented by the formula M.sup.I M.sup.III (XO.sub.4).sub.2.12H.sub.2 O wherein M I represents a mono-valent metal atom or an ammonium group, M III represents a tri-valent metal atom, and X represents a sulfur atom or a selenium atom.
Claim 8
Dependent Claim 17 words
A waterproofing method as in claim 1, 2, 3 or 5, wherein X represents a sulfur atom.
Claim 9
Dependent Claim 13 words
A waterproofing method as in claim 4, wherein X represents a sulfur atom.
Claim 10
Dependent Claim 65 words
A waterproofing method for an ink jet record as in claim 5, wherein a sulfate or a tri-valent metal for forming said compound is applied on the surface of a recording sheet for forming ink jet records, and a sulfate of a mono-valent metal for said compound is jetted from a nozzle of the ink jet printer together with an aqueous ink jet recording ink.
Claim 11
Dependent Claim 33 words
