Title:
LAMINATED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2017/155006
Kind Code:
A1
Abstract:
A laminated article containing an organic piezoelectric material having a weight average molecular weight of 50,000 to 1,000,000. In the laminated article, the normalized molecular orientation (MORc) measured by a microwave transmission-type molecular orientation meter with the reference thickness being 50 μm is 1.0 to 15.0, and the crystallinity degree obtained by the DSC method is 20%-80%. The laminated article has a polymer film (A) in which the internal haze with respect to visible light is 50% or less, and a peelable protective film (B) in contact with one surface of the polymer film (A). The maximum indentation depth hmax when the surface side of the protective film (B) in contact with the polymer film (A) is measured by the nanoindentation method is 53 nm to 100 nm.
