Abstract:
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 &mgr;m, 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 &mgr;m to 10 &mgr;m and at least one peak in a pore radius range of from 0.001 &mgr;m to 0.1 &mgr;m and the total volume of pores having radii of from 0.1 &mgr;m to 20 &mgr;m is not less than 0.5 cm3/g.
