TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The pigment is a dispersion of 60% titanium dioxide in a binder, or dispersion including titanium dioxide and a solvent (s2) selected from propylene glycol monomethyl ether acetate (PMAC), and/or xylene. The solvent (s1) is selected from cyclohexanone, acetate ester, and/or butyrolactone. The fluorinated vinyl ether is fluoroethylene-alkyl vinyl ether.    TECHNOLOGY FOCUS - POLYMERS - Preferred Backsheet: The photovoltaic backsheet further comprises a layer of ethylene vinyl acetate adjacent to the coating. Preferred Method: The applying of the coating is performed by at least one technique selected from reverse roll, gravure, slot die, meyer rod, and/or spray. The curing is performed by heating the coating to 138-182 degrees C or 93-182 degrees C for 1-5 minutes. Preferred Coating: In the coating, the weight percent of the acrylic polymer is 20%. The coating prior to curing also includes a crosslinker (7-10 wt.%). The coating prior to curing also includes pigment and binder, where the weight ratio of the pigment to the binder is 0.1-1.1 (preferably 0.5-0.9, especially 0.6-0.7). The thickness of the coating prior to curing is 0.1-1 (preferably 0.25-0.75, especially 0.25-0.5, particularly 0.25) mil. The UV transmission of the coating after curing is less than 0.12%. The coating prior to curing comprises (parts by weight): the acrylic polymer (20-40, preferably 30), the polyvinylidene fluoride (50-120, preferably 70), the crosslinker (1-20, preferably 7), and pigment (50-120, preferably 78); and further comprises solvent (s1) (70-160, preferably 100), dispersant, catalyst, UV absorber, and antioxidant. The coating prior to curing comprises (parts by weight): at least one fluorinated vinyl ether (80-120, preferably 100), at least one isocyanate crosslinker (5-35, preferably 9-28), and pigment dispersion (50-150, preferably 80-130); and further comprises UV absorber (0.5-1, preferably 0.72), solvent (preferably 2,4-pentanedione) (1-10, preferably 5). The coating composition (C1) comprises (parts by weight): the acrylic polymer (20-40), the polyvinylidene fluoride (50-120), the (1-20), and the pigment (50-120); or fluorinated vinyl ether (80-120), at least one isocyanate crosslinker (5-35), and pigment dispersion (50-150). Preferred Components: The polyvinylidene fluoride is selected from copolymers of vinylidene fluoride and hexafluoropropylene, and/or homopolymers of polyvinylidene fluoride. The acrylic polymer is formed from methyl methacrylate, n-butyl methacrylate, hydroxyethyl methacrylate, or methacrylic acid. The crosslinker is a melamine crosslinker or isocyanate crosslinker. The substrate includes polyester (preferably polyethylene terephthalate). EXAMPLE - No suitable example given.
