PURPOSE: A fluorinated polymer-perfluoroalkyl group-containing acryl particle is provided to have excellent film-forming properties as a coating agent for a back sheet of a solar cell, and to able to form a coating with excellent weatherability and waterproofness. CONSTITUTION: A fluorinated polymer-perfluoroalkyl group-containing acryl particle is manufactured by followings: a step of preparing seed particles by copolymerizing a vinylidene fluoride homopolymer or vinylidene fluoride homopolymer; and a step of polymerizing a fluorine-containing-(meth)acrylic acid ester, non-fluorine-based (meth)acrylic ester and acrylamide-based monomer under the presence of seed particles. The fluorine-containing (meth)acrylic acid ester is C4-20 perfluoroalkyl-containing (meta)ester acrylate. |
