US 12,109,832 B2 · Film for latex ink

Abstract

An object is to provide a film for latex ink having a latex ink-receiving layer containing an acrylic resin, the latex ink-receiving layer having excellent adhesion to both a printed portion using latex ink and a base material. Then, the object is achieved by the following: a film for latex ink having a laminate structure in which a latex ink-receiving layer (X) and a base material (Y) are stacked, in which the latex ink-receiving layer (X) is formed of a resin composition (x1) containing an acrylic resin (A) having a cross-linkable functional group and a cross-linking agent (B), and the cross-linking agent (B) contains an isocyanurate compound (B1) and a modified product (B2) of the isocyanurate compound.
