STACKED AND BIAXIALLY STRETCHED POLYESTER FILM FOR OPTICAL USE

摘要

The present invention relates to a multi-layered biaxial elongated polyester film for an optical use which can increase inner tub adhesion to maintain adhesion between a solventless ultraviolet (UV) hardening resin and a polyester film of 90% or more after processing for two hours by immersing in boiling water, thereby having a uniform exterior and excellent adhesion since a resin is wet well in a primer multi-layered film.
