Document Type and Number:
WIPO Patent Application WO/2020/137879
Kind Code:
A1
Abstract:
[Problem] To provide a powder liquid dispersion that has excellent dispersibility, has less powder fall-off when used to form a layer (coating film), and allows improvement of the smoothness and UV workability of a surface of the obtained layer (coating film); and a layered product and printed base board obtained by using the powder liquid dispersion. [Solution] The powder liquid dispersion according to the present invention contains: a powder of a tetrafluoroethylene polymer; a (meth)acrylate polymer; a polyimide precursor or a polyimide; and a polar organic solvent, wherein the contained amount of the tetrafluoroethylene polymer is 10-60 mass%, and the ratio by mass of the contained amount of the polyimide precursor or polyimide with respect to the contained amount of the tetrafluoroethylene polymer is 0.3 or less.
