摘要

Provided is a laser marking multilayer film that includes: a layer (X) at least as an outermost layer, the layer (X) being made from a resin composition (x) containing a bisphenol-based polycarbonate (A) and a polyester (B), the polyester (B) containing a predetermined compound as a diol component, the resin composition (x) containing the predetermined compound in an amount of 0.1 to 20 mass %; and at least one layer (Y) made from a resin composition (y) containing the bisphenol-based polycarbonate (A) and a laser beam energy absorber (C). The multilayer film does not contaminate equipment such as a T-die and rolls in melt extrusion molding, brings about good laser marking performance. On the multilayer film, laser-marked information does not fade even in long-term use. In the multilayer film, the base material does not deteriorate.
