Recording medium for ink and method for producing the same

A method for producing a recording medium for ink including an ink receiving portion for receiving an ink and holding a coloring agent in the ink, the method comprising:

• a first step of applying, on a support member on which a water-soluble reactive substance capable of reacting with said coloring agent and holding the coloring agent is formed, an aqueous liquid including a component for forming a porous layer;
• a second step of applying, on said porous layer, a second reactive substance for terminating the reaction of said water-soluble reactive substance;
• and
• a third step of forming, on the surface on which said second reactive substance is formed, an ink receiving layer containing at least a pigment for holding the coloring agent of the ink, and a binder for said pigment.

A method for producing a recording medium for ink comprising:

• a step of forming a water-soluble cationic substance capable of reacting with an anionic coloring agent on a surface of a support member;
• a step of applying an aqueous liquid containing a component capable of forming a porous layer on a surface on which said water-soluble cationic substance is formed;
• a first surface treatment step of applying, drying and solidifying a first coating liquid containing at least a crosslinking agent selected from the group consisting of boric acid and borate salts on said porous layer;
• a second surface treatment step of applying a second coating liquid containing at least one compound selected from the group consisting of boric acid and borate salts on a solidified surface formed in said first surface treatment step;
• and
• a step of applying a third coating liquid containing at least a pigment, polyvinyl alcohol and at least one crosslinking agent selected from the group consisting of boric acid and borate salts while said second coating liquid maintains a moist state.
