Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
64 words
A recording medium provided with an ink receiving layer on a substrate, wherein said ink receiving layer comprises an alumina hydrate having a boehmite structure and a zirconium compound that provides a zirconium ion when an aqueous ink comprising an anionic dye is applied on the ink receiving layer, the zirconium ion making the ink receiving layer's ability to adsorb the anionic dye increase.
Claim 2
Dependent Claim
64 words
A recording medium provided with an ink receiving layer on a substrate, wherein said ink receiving layer comprises an alumina hydrate having a boehmite structure and a zirconium compound that provides a zirconium ion when an aqueous ink comprising an anionic dye is applied on the ink receiving layer, the zirconium ion making the ink receiving layer's ability to adsorb the anionic dye increase.
Claim 3
Dependent Claim
