Abstract
A recording medium comprises a base member and at least a porous organic resin layer formed on the base member. The porous organic resin layer includes organic fine particles having both hydrophilic radicals and hydrophobic radicals, a water-absorbing binder and voids. The layer shows a pore size distribution having a highest peak found within a pore radius range between 3 nm and 300 nm, a pore volume of 0.2 cm3/g or more and a pH value of 5.2 or higher as observed by a method conforming to JIS P 8133. The layer is typically formed by applying to the base member a coating formulation of aqueous dispersion containing such organic fine particles, a water-absorbing binder and a basic substance and showing a pH value of 5.2 or higher as observed by a method conforming to JIS Z 8802, followed by drying.

A recording medium comprising:
- a base member and
- at least a porous organic resin layer on said base member;
- said porous organic resin layer including organic fine particles having both hydrophilic and hydrophobic groups, and a water-absorbing but water-insoluble resinous binder;
- wherein said porous organic resin layer has a pore size distribution having the highest peak found within the pore radius range between 3 nm and 300 nm, a pore volume of 0.2 cm3/g to 1.0 cm3/g and a pH value of 5.2 to 8.5 as observed by a method conforming to JIS P 8133.
