Abstract

A fluoropolymer liquid composition including a fluoropolymer liquid (A) which includes a liquid medium and a crosslinkable functional group-containing crosslinkable fluoropolymer. The fluoropolymer liquid (A) is a fluoropolymer liquid dispersion (AD) having, dispersed in a liquid dispersion medium, particles of a crosslinkable fluoropolymer (PD) containing acid/acid salt groups or organic groups capable of undergoing hydrolysis and thus being converted to carboxyl groups, or a fluoropolymer solution (AS) having, dissolved in a fluorosolvent or an alcohol/water mixed solvent, a crosslinkable fluoropolymer (PS) containing acid/acid salt groups or acid/acid salt groups precursors. Further, the crosslinkable functional group is a cyano group, —I or —Br.
