Abstract
Provided is a recording medium provided with a porous ink-receiving layer containing thermoplastic resin particles and an inorganic pigment laminated on a substrate, wherein the pore radius distribution curve of said porous ink-receiving layer has a maximum peak in a pore radius range of from 1 μm to 10 μm and at least one peak in a pore radius range of from 0.001 μm to 0.1 μm and the total volume of pores having radii of from 0.1 μm to 20 μm is not less than 0.5 cm3/g.
Claims11
A recording medium provided with a one-layered porous ink-receiving layer containing pores composed of voids formed by mutual fusion of thermoplastic resin particles and a porous inorganic pigment formed on a substrate, wherein 50% or more of all of said thermoplastic resin particles have a particle diameter within a range of from 1 to 100 μm, and the average particle diameter of aggregates of said porous inorganic pigment is 0.1 to 1 times the average particle diameter of said thermoplastic resin particles, and wherein a pore radius distribution curve of said porous ink-receiving layer has a maximum peak in a pore radius range of from 1 μm to 10 μm and at least one peak in a pore radius range of from 0.001 μm to 0.1 μm and the total volume of pores having radii of from 0.1 μm to 20 μm is not less than 0.5 cm3/g.
A recording method comprising the step of:
- ejecting ink from an ink-jet system onto a recording medium provided with a one-layered porous ink-receiving layer containing pores composed of voids formed by mutual fusion of thermoplastic resin particles and a porous inorganic pigment formed on a substrate, wherein 50% or more of all of said thermoplastic resin particles have a particle diameter within a range of from 1 to 100 μm, and the average particle diameter of aggregates of said porous inorganic pigment is 0.1 to 1 times the average particle diameter of said thermoplastic resin particles, and wherein a pore radius distribution curve of said porous ink-receiving layer has a maximum peak in a pore radius range of from 1 μ to 10 μm and at least one peak in a pore radius range of from 0.001 μm to 0.1 μm and the total volume of pores having radii of from 0.1 μm to 20 μm is not less than 0.5 cm3/g.
