Zusammenfassung:	PURPOSE:To provide the subject composition improving the weather resistance, chemical resistance and adhesivity of polycarbonate by compounding a hydroxyl group-containing fluoropolymer, a curing agent, a polymer for imparting adhesivity to the polycarbonate, an UV absorber, a light stabilizer and a specific solvent as essential components. CONSTITUTION:The objective composition comprises (A) a fluoropolymer having a hydroxyl group in the molecule (preferably a polymer comprising units based on chlorotrifluoroethylene, vinyl carboxylate ester, hydroxy group-containing allyl ether and other monomers in contents of 25-75mol%, 10-70mol%, 3-40mol% and 0-20mol%, respectively), (B) a curing agent compatible with the polymer, (C) a polymer for imparting adhesivity [preferably (meth)acrylic resin], (D) an UV absorber, (E) a light stabilizer and (F) a solvent mainly containing a cyclic ether as essential components.
