An aqueous primer composition includes a water-soluble multivalent metal salt, a polyester-based polyurethane emulsion, and water. A set includes the aqueous primer composition and an inkjet recording ink composition. A printed matter obtained by using the set includes a base material layer, a primer layer containing the water-soluble multivalent metal salt and the polyester-based polyurethane, and a printing layer. The aqueous primer can offer excellent preservation stability, and can allow for formation of a printing layer having high adhesion, capable of forming high-quality images with little bleeding/mottled appearance when printing images, text, etc., to form a printing layer on a plastic film or other nonabsorbent medium using inkjet recording ink compositions, offering excellent water resistance and lamination suitability.
An aqueous primer composition made for nonabsorbent media and containing a water-soluble multivalent metal salt, a polyester-based polyurethane emulsion, a surface-active agent, and water,
A printed matter comprising a base material layer, a primer layer formed from an aqueous primer composition containing a water-soluble multivalent metal salt and a polyester-based polyurethane emulsion as well as a surface-active agent, and a printing layer,
