Title:
LAMINATE FILM FOR BONDING, AND LIGHT-TRANSMITTING LAMINATE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2020/242144
Kind Code:
A1
Abstract:
A laminate film for bonding according to an embodiment and a light-transmitting laminate including same provide a laminate film or the like which has improved optical characteristics while exhibiting a sound-insulating ability. The laminate film for bonding can use a method, such as one for applying a metal salt additive to a core layer, to substantially prevent a trace of a melt fracture of the core layer, which can form during an extrusion process, from remaining after glass bonding, can substantially prevent optical defection-distortion from occurring while maintaining a sufficient sound-insulating ability, and employs a high refractive ultraviolet absorbing agent as an inhibitor for suppressing change over time to suppress changes in yellow index, refractive index, etc. over time, thereby providing a laminate film having stable physical properties.
