Document Type and Number:
WIPO Patent Application WO/2020/116209
Kind Code:
A1
Abstract:
The present invention provides a multilayer film for laser printing, which is characterized by having: at least one layer (X) that serves as an outermost layer, while being formed from a resin composition which contains (A) a bisphenol polycarbonate and (B) a polyester that contains a specific compound as a diol component, and which contains the specific compound in an amount of 0.1-20% by mass; and at least one layer (Y) that is formed from a resin composition which contains (A) a bisphenol polycarbonate and (C) a laser light energy absorbent. Consequently, the present invention provides a multilayer film for laser printing, which does not contaminate equipment such as a T-die and a roll during melt extrusion molding, and which has good laser printing performance, while being prevented from deterioration of the base material and color fading of laser print of information even during a long period of use.
