摘要：
Provided is a composition comprising a polytetrafluoroethylene, a polymer (I) containing a polymerization unit (I) based on a monomer represented by the general formula (I), a nonionic surfactant, and an aqueous medium, wherein a content of the polytetrafluoroethylene in the composition is 10% by mass or more based on the composition, and a content of the nonionic surfactant in the composition is 1.0% by mass or more based on the polytetrafluoroethylene,
CX 1 X 3 =CX 2 R(-CZ 1 Z 2 -A 0 ) m (I)
wherein X 1 and X 3 are each independently F, Cl, H, or CF 3 ; X 2 is H, F, an alkyl group, or a fluorine-containing alkyl group; A 0 is an anionic group; R is a linking group; Z 1 and Z 2 are each independently H, F, an alkyl group, or a fluorine-containing alkyl group; and m is an integer of 1 or more.
CX 1 X 3 =CX 2 R(-CZ 1 Z 2 -A 0 ) m (I)
wherein X 1 and X 3 are each independently F, Cl, H, or CF 3 ; X 2 is H, F, an alkyl group, or a fluorine-containing alkyl group; A 0 is an anionic group; R is a linking group; Z 1 and Z 2 are each independently H, F, an alkyl group, or a fluorine-containing alkyl group; and m is an integer of 1 or more.
