Title:
METHOD FOR MANUFACTURING LAYERED BODY
Document Type and Number:
WIPO Patent Application WO/2019/171877
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a layered body provided with an optical film with improved orientation. In a first heating step (P1), a dry coating film (97) that includes a liquid crystal polymer (21) and a dichroic compound (31) is heated, bringing the dry coating film (97) to a first temperature (T1) that is higher than the melting point of the dichroic compound. In a first cooling step (P2), the dry coating film (97) is cooled, bringing the dry coating film (97) to a second temperature (T2) that is lower than the crystallization temperature (Tc) of the dichroic compound (31) and lower than the crystallization temperature (Ts) of the liquid crystal polymer (21). In a second heating step (P3), the dry coating film (97), having passed through the first cooling step (P2), is heated, bringing the dry coating film (97) to a third temperature (T3) that is lower than the nematic transition temperature (Tne) of the liquid crystal polymer (21).
