Title: MULTILAYER LAMINATION FILM FOR LASER PRINTING AND PACKAGE BODY AND PRINTING BODY FORMED THEREBY, AND INK COMPOSITION FOR LASER PRINTING USED THEREFOR
Abstract:
Provided is a multilayer lamination film for laser printing that does not require a special ink that discolors by laser light irradiation, and that makes it possible to obtain a printed line having high visibility by irradiation of laser light having a power sufficiently low to avoid damaging a base film. The multilayer lamination film for laser printing includes at least a base material layer, a printing layer, and a sealant layer. The printing layer is a layer made of an ink composition enabling printing by means of laser light. The ink composition is made of white ink containing at least a titanium oxide and a binder resin, the binder resin containing a crystalline component.
