Abstract
Abstract An ink-jet recording method is described for producing a recorded image on an image-receiving sheet with a jet of aqueous ink, wherein an ink jet is projected onto an image-receiving sheet comprising a surface layer containing a pigment, and said surface layer is capable of adsorbing a coloring component in said aqueous ink.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
67 words
An ink-jet recording method for producing a recorded image on an image-receiving sheet with a jet of aqueous ink, wherein an ink-jet is projected onto an image-receiving sheet with a surface layer containing a pigment and an adhesive, and having an Rf value, which is the flow rate measured for a combination of said surface layer and a dye in said aqueous ink, of less than 0.59.
Claim 2
Dependent Claim
67 words
An ink-jet recording method for producing a recorded image on an image-receiving sheet with a jet of aqueous ink, wherein an ink-jet is projected onto an image-receiving sheet with a surface layer containing a pigment and an adhesive, and having an Rf value, which is the flow rate measured for a combination of said surface layer and a dye in said aqueous ink, of less than 0.59.
Claim 3
Dependent Claim
16 words
An ink-jet recording method as in claim 1, wherein said Rf value is less than 0.5.
Claim 4
Dependent Claim
29 words
An ink-jet recording method as in claim 1, wherein said pigment is zeolite, acid clay, diatomaceous earth, or a synthetic silicate, and said aqueous ink comprises a basic dye.
