Abstract
(EN)
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.

La présente invention concerne un film multicouche pour impression laser, qui est caractérisé en ce qu'il comprend : au moins une couche (X) qui sert de couche la plus à l'extérieur, tout en étant formée à partir d'une composition de résine qui contient (A) un polycarbonate de bisphénol et (B) un polyester qui contient un composé spécifique en tant que constituant diol, et qui contient le composé spécifique en une quantité de 0,1 à 20 % en masse ; et au moins une couche (Y) qui est formée à partir d'une composition de résine qui contient (A) un polycarbonate de bisphénol et (C) un absorbant d'énergie de lumière laser. Par conséquent, la présente invention concerne un film multicouche pour impression laser, qui ne contamine pas un équipement tel qu'une matrice en T et un rouleau pendant le moulage par extrusion à l'état fondu, et qui présente une bonne performance d'impression au laser, tout en étant exempt de détérioration du matériau de base et de l'affaiblissement de couleur de l'impression laser d'informations même pendant une longue période d'utilisation.
