Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1 . 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, wherein the water-soluble multivalent metal salt is one or more salts selected from the group consisting of a salt of an organic acid of a multivalent metal, a salt of an inorganic acid of a multivalent metal, and a hydrate of any of the forgoing, wherein the only multivalent metal is calcium, wherein a compounding quantity of the water-soluble multivalent metal salt is 0.1% by mass to 20.0% by mass in equivalent solids content in the aqueous primer composition, and the surface-active agent is constituted by one or more surface-active agents selected from the group consisting of acetylenediol-based surface-active agents, silicone-based surface-active agents, and fluorine-based surface-active agents, wherein a content of the surface-active agent is 0.1% to 1.0% by mass relative to 100% by mass of the aqueous primer composition. 2 . The aqueous primer composition according to claim 1 , wherein a content of the polyester-based polyurethane emulsion is 0.1% by mass to 25.0% by mass in equivalent resin solids content in the aqueous primer composition. 3 . A set including the aqueous primer composition according to claim 1 , and an inkjet recording ink composition. 4 . A set including the aqueous primer composition according to claim 2 , and an inkjet recording ink composition. 5 . 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, wherein the water-soluble multivalent metal salt is one or more salts selected from the group consisting of a salt of an organic acid of a multivalent metal, a salt of an inorganic acid of a multivalent metal, and a hydrate of any of the forgoing, wherein the only multivalent metal is calcium, wherein a compounding quantity of the water-soluble multivalent metal salt is 0.1% by mass to 20.0% by mass in equivalent solids content in the aqueous primer composition, and the surface-active agent is constituted by one or more surface-active agents selected from the group consisting of acetylenediol-based surface-active agents, silicone-based surface-active agents, and fluorine-based surface-active agents, wherein a content of the surface-active agent is 0.1% to 1.0% by mass relative to 100% by mass of the aqueous primer composition.
