Title:
POLYCARBONATE RESIN FILM, TRANSPARENT FILM, AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2012111964
Kind Code:
A
Abstract:

To provide a polycarbonate resin film which contains constituent units derived from a specific dihydroxy compound and has excellent mechanical strength and thickness evenness, and to provide a method for producing a transparent film.

The polycarbonate resin film contains at least constituent units derived from a dihydroxy compound having a linking structure represented by structural formula (1). The polycarbonate resin film satisfies the following formula (2) when examined through a tensile test at a pulling rate (strain rate) of 1,000 %/min at a reference stretching temperature of the polycarbonate resin (wherein, no hydrogen atom is bonded to the oxygen atom contained in the structural formula (1), and 0.9≤(tensile lower yield stress)/(tensile upper yield stress)≤1 (2)).
