Abstract: Provided are: a two-pack air-drying type water-borne paint composition comprising a first agent and a second agent, wherein the first agent contains a water-borne epoxy-based amine resin (A) that has at least one amino group selected from the group consisting of a primary amino group and a secondary amino group in a molecule thereof and has an amine equivalent of 500 to 2000, and the second agent contains an epoxy resin emulsion (B); and a water-borne epoxy-based amine resin (A) that can be used for the paint composition.

Abstract: Provided is an air-drying type water-borne paint composition including a water-borne resin (A) and an emulsion (B) of an ethylene-vinyl acetate copolymer having an ethylene content ratio of 5 to 50% by mass, wherein a content of the ethylene-vinyl acetate copolymer is 5 to 50% by mass, relative to a resin solid content in the air-drying type water-borne paint composition. The air-drying type water-borne paint composition may be a two-pack water-borne paint composition including a first agent containing the water-borne resin (A) and a second solution containing a curing agent (C).
