Abstract
A film for latex ink including a latex ink-receiving layer achieving excellent ink adhesion and excellent scratch resistance. A film having a laminate structure in which a latex ink-receiving layer and a substrate are layered, and the latex ink-receiving layer formed from a resin composition containing an acrylic resin having a cross-linkable functional group, a specific cross-linking agent, an ultraviolet curable acrylate compound, and a photopolymerization initiator.
Claims8
A film for latex ink, comprising:
- a laminate structure wherein a latex ink-receiving layer (X) and a substrate (Y) are layered,
- wherein
- the latex ink-receiving layer (X) comprises a resin composition (x1) comprising an acrylic resin (A) having a cross-linkable functional group, a cross-linking agent (B), an ultraviolet curable acrylate compound (C), and a photopolymerization initiator (D),
- the cross-linking agent (B) comprises at least one compound selected from the group consisting of an isocyanurate compound (B1) and an aromatic polyisocyanate (B2),
- the isocyanurate compound (B1) comprises an isocyanurate compound (B1-1) and a modified product (B1-2) of an isocyanurate compound,
- the isocyanurate compound (B1-1) is a trimer of 1,6-hexamethylene diisocyanate,
- the modified product (B1-2) of the isocyanurate compound is a trimer of 1,6-hexamethylene diisocyanate, and comprises a tertiary amino group, and
- a content ratio [(A)/(C)] of the acrylic resin (A) to the ultraviolet curable acrylate compound (C) in terms of mass ratio is from 5/95 to 30/70.
