Title:
LAYERED BODY PRODUCTION METHOD AND OPTICAL MEMBER PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/066910
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a layered body production method that is excellent for transferring an optical layer containing a functional layer selected from the group consisting of a cholesteric liquid crystal layer and a phase contrast layer onto another substrate and also to provide an optical member production method. The present invention provides a layered body production method for producing a laminate comprising a temporary support and an optical layer disposed adjacently on the temporary support, said optical layer including a functional layer, wherein the method involves: a step for forming a precursor layer containing a liquid crystal compound having a polymerizable group directly on the temporary support or with another layer interposed therebetween; and a step for aligning the liquid crystal compound in the precursor layer, then curing the precursor layer by exposing the surface of the precursor layer on the opposite side from the temporary support to light in order to obtain the functional layer. The precursor layer contains the partial structure represented by formula (1), the light in the light exposure includes 265 nm-wavelength light, and the dose of the 265 nm-wavelength light is 5 mJ/cm2 or greater.
