To provide an fluorescent aqueous paint composition excellent in color development and heat stability, and preventing the evaporation of formaldehyde.

This aqueous fluorescent paint composition, which is a paint using a fluorescent pigment, contains a formalin catcher agent as an essential component. This aqueous fluorescent paint composition contains a formalin catcher agent to an aqueous fluorescent paint composition using especially a fluorescent pigment containing a melamine/formaldehyde resin or a benzoguanamine/formaldehyde resin. Thus, this aqueous fluorescent paint composition contains formaldehyde at a low concentration and excellent in color development of fluorescence and heat stability.
