Title:
METHOD FOR PRODUCING MULTILAYER BODY AND LIQUID COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2021/157507
Kind Code:
A1
Abstract:
[Problem] To provide: a multilayer body which has a polymer layer that is provided with the physical properties of a tetrafluoroethylene polymer and the physical properties of a maleimide compound; and a liquid composition which contains a tetrafluoroethylene polymer and a maleimide compound. [Solution] A method for producing a multilayer body according to the present invention forms a polymer layer by: applying a liquid composition, which contains a powder of a tetrafluoroethylene polymer having a melting temperature of 260°C or more and a thermosetting compound having a maleimide group and an arylene group, to the surface of a base material layer; heating the liquid composition at a temperature that is not less than 100°C but less than the melting temperature of the tetrafluoroethylene polymer; and further heating the liquid composition at a temperature that is not less than the melting temperature of the tetrafluoroethylene polymer. A liquid composition according to the present invention contains a powder of a specific tetrafluoroethylene polymer and the above-described thermosetting compound.
