Abstract
Provided is a fine powder material for forming an ink-receiving layer on a recording medium, wherein a pore radius maximum exists within a range of from 90 to 120 Å in a pore radius distribution of said fine powder material and wherein a total volume of pores having radii not exceeding 50 Å is not more than 6.0% of a volume of all pores.
Claims4
A recording medium, comprising an alumina hydrate in an ink-receiving layer provided on a substrate, said alumina hydrate having a pore radius maximum N2 in its pore radius distribution and being obtained by subjecting to a secondary treatment a raw alumina hydrate having a pore radius maximum N1 in its pore radius distribution,
- wherein N2 is less than N1, N2 is within a range of from 90 to 120 Å, and after the secondary treatment the total volume of all pores having radii not exceeding 50 Å in the pore radius distribution of the alumina hydrate in the ink-receiving layer is not more than 6.0% of the total volume of all pores in the pore radius distribution of the alumina hydrate in the ink-receiving layer.
A recording medium having an ink-receiving layer which consists essentially of an alumina hydrate and a binder, and formed on a base material, wherein said alumina hydrate has a pore radius maximum N2 within a range of from 90 to 110 Å and the total volume of all pores having radii not exceeding 50 Å in the pore radius distribution of said ink-receiving layer is not more than 10.0% of the total volume of all pores in the pore radius distribution of said ink-receiving layer.
A recording medium having an ink-receiving layer which is comprised of an alumina hydrate and a binder, and formed on a base material, wherein said alumina hydrate has a pore radius maximum within a range of from 90 to 110 Å;
- and the total volume of all pores having radii not exceeding 50 Å in the pore radius distribution of said alumina hydrate is not more than 6.0% of the total volume of all pores in the pore radius distribution of said alumina hydrate, wherein the total volume of pores having radii not exceeding 50 Å in the pore radius distribution of said ink-receiving layer is not more than 10.0% of the total volume of all pores in the pore radius distribution of said ink-receiving layer.
