Abstract: The invention provides a back sheet including a water-impermeable sheet and a film firmly bonded to each other and exhibiting excellent adhesiveness to an EVA encapsulant layer of a solar cell module even without corona discharge treatment on the film surface. The back sheet of the invention is a back sheet for solar cell module, including a water-impermeable sheet and a film. The film is disposed on at least one side of the water-impermeable sheet and is formed from a coating containing a fluorine-containing copolymer. The fluorine-containing copolymer contains a C2-C3 perhaloolefin structural unit, a vinyl acetate structural unit, a hydroxy-containing vinyl monomer structural unit, and a carboxy-containing monomer structural unit.

Abstract: The disclosure provides an aqueous dispersion that can provide a film having excellent weather resistance and excellent hardness and that has excellent dispersion stability. The aqueous dispersion contains a fluorine-containing polymer that contains: a polymerized unit (a) based on a fluorine-containing monomer; a polymerized unit (b) based on a carboxy group-containing monomer; and a polymerized unit (c) based on a hydroxy group-containing monomer. The polymerized unit (b) is contained in an amount of 4.0 to 14.0 mol % of all polymerized units and the polymerized unit (c) is contained in an amount of 14.0 to 35.0 mol % of all polymerized units.
