Abstract
Official abstract text for this publication.
It is an object of the present invention to provide a primer composition for surface-printed flexible packaging, an ink set, a surface-printed matter, and an inkjet printing method, which can impart excellent solid uniformity, bleeding resistance, abrasion resistance, alcohol resistance, and heat resistance to a coating film when an inkjet image is formed after applying the primer composition. Provided is a primer composition for surface-printed flexible packaging comprising an acryl-based resin emulsion emulsified with a polymer, N-oleoyl sarcosine, a hydrazine-based compound having at least two or more hydrazine residues in a molecule, and wax, wherein a content of the acryl-based resin emulsion is 3 to 40% by mass in terms of solid content, and wherein a glass transition temperature of the acryl-based resin emulsion is-40 to 30° C.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A primer composition for surface-printed flexible packaging, comprising an acryl- based resin emulsion emulsified with a polymer, N-oleoyl sarcosine, a hydrazine-based compound having at least two or more hydrazine residues in a molecule, and wax, wherein a content of the acryl-based resin emulsion is 3 to 40% by mass in terms of solid content, and wherein a glass transition temperature of the acryl-based resin emulsion is −40 to 30° C. 2 . The primer composition for surface-printed flexible packaging of claim 1 , further comprising a white pigment. 3 . The primer composition for surface-printed flexible packaging of claim 1 , further comprising a chlorinated polyolefin. 4 . An ink set, including the primer composition for surface-printed flexible packaging of claim 1 and an aqueous inkjet ink composition, wherein the aqueous inkjet ink composition comprises a pigment, a water-insoluble resin, and wax. 5 . A surface-printed matter to which the primer composition for surface-printed flexible packaging and the aqueous inkjet ink composition of claim 4 are applied. 6 . An inkjet printing method, including a printing step of surface-printing the primer composition for surface-printed flexible packaging and the aqueous inkjet ink composition of claim 4 on a base material.
