Title:
COMPOSITION, LAMINATE , AND FILM OF TETRAFLUOROETHYLENE-BASED POLYMER
Document Type and Number:
WIPO Patent Application WO/2022/113926
Kind Code:
A1
Abstract:
Provided are a composition and a laminate or a film, in which the absorption factor in an ultraviolet ray wavelength range of a tetrafluoroethylene-based polymer is improved while any deterioration in electrical properties is suppressed. This composition includes: particles of a tetrafluoroethylene-based polymer having a fluorine content of 70 mass% or more; and an ultraviolet ray absorbing agent that has a molecular weight of 250 or more and that has a hydroxyl group and a nitrogen-containing heterocyclic structure. The laminate or the film according to the present invention has at least one layer that contains a tetrafluoroethylene-based polymer having a carbonyl group-containing group and having a fluorine content of 70 mass% or more, and an ultraviolet ray absorbing agent having a molecular weight of 250 or more and having a hydroxyl group and a nitrogen-containing heterocyclic structure, and that has a light-beam absorption factor of 80% or more at a wavelength of 255-355 nm per 1 μm of thickness.
