Abstract
Provided is a weatherable backsheet for solar cell modules which comprises a cured coating film and a water-impermeable sheet, the cured coating film having improved secondary adhesion to the water-impermeable sheet. The backsheet is produced using a coating composition having a prolonged usable life, and film blocking phenomenon during the production can be avoided. The weatherable backsheet for solar cell modules comprises a water-impermeable sheet and a cured coating film layer formed on at least one surface thereof, the coating film layer comprising a cross-linked product of a coating composition which comprises a hydroxylated fluoropolymer and silicon oxide particles having an average primary-particle diameter of 0.1 to 30 μm.
