Abstract
The present invention provides a weather-resistant sheet for a solar cell module, which has better adhesion to a water impermeable sheet, better blocking resistance against the water impermeable sheet, and better adhesion to EVA that is a sealant; a weather-resistant sheet for a solar cell module in which a cured coating film layer thereof can suppress UV transmission significantly; a product including the sheet; and a process for producing the sheet. The weather-resistant sheet for a solar cell module includes, on a water impermeable sheet, a cured coating film layer made of a crosslinked product of a coating composition that includes a hydroxyl group-containing fluoropolymer, wherein in a pressure-resistance test performed when a crosslinking degree of the cured coating film layer is 80 to 99%, the cured coating film layer and the water impermeable sheet without a cured coating film layer formed thereon are not adhered to each other after a load has been applied to the cured coating film layer and the water impermeable sheet being stacked.
