Title:
PROCESS FOR PRODUCING RESIN FILM, RESIN FILM, POLARIZER, AND LIQUID-CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/096161
Kind Code:
A1
Abstract:
Disclosed is a process for producing a resin film through solution casting, the process including a casting step in which a resin solution (dope) (16) is ejected from the orifice (21b) of a casting die (20) and cast on an endless-belt support (11) and, simultaneously therewith, a solvent in which the transparent resin as a component of the dope is soluble is caused to flow down from both longitudinal ends of the orifice (21b) of the casting die (20). The process satisfies relationship (1):
-5 < T2 - T1 < 5 (1)
(wherein T1 indicates the temperature [ºC] of the solvent which has just left the orifice, and T2 indicates the temperature [ºC] of the solvent which has just reached to the support).
