Abstract
A recording medium including a substrate and an ink-receiving layer provided on the substrate. The ink-receiving layer contains a silica particle and a water-insoluble resin. The silica particle satisfies the following expressions 1 and 2 when the average pore radius thereof determined by the BJH method is taken as r (nm), and the oil absorption thereof measured by the linseed oil droplet method is taken as V (ml/100 g): r≦5.0 (nm) expression 1: V/r≧80 ((ml/100 g)/nm). expression 2:
