Abstract: The present invention provides a method for producing an aqueous carbodiimide having excellent crosslinking reactivity with a crosslinking group, such as an alcoholic hydroxy group of an aqueous resin. The method for producing an aqueous carbodiimide-containing liquid includes a step (1) of mixing an isocyanate group-containing carbodiimide (A), a terminal blocking agent, and at least one organic metal compound selected from an organic titanium compound, an organic zirconium compound, and an organic aluminum compound and allowing them to react with each other, to obtain a terminal-blocked carbodiimide (B) in which the isocyanate group is blocked with the terminal blocking agent; and a step (2) of dissolving or dispersing the terminal-blocked carbodiimide (B) in an aqueous solvent, to obtain an aqueous carbodiimide-containing liquid, wherein the terminal blocking agent contains a hydrophilic compound (X) having a functional group having reactivity with the isocyanate group and a hydrophilic group other than the functional group.
