(57) [Summary] [Structure] A number average molecular weight of 500 to 5 containing fluorine in the molecule and having active hydrogen and / or an epoxy group. 50,000 resin (A) and an acrylic resin (B) having a number average molecular weight of 500 to 50,000, which has an ultraviolet absorbing ability and / or an antioxidant ability and / or a radical scavenging ability in the molecule. And a weight ratio of the resin (A) to the resin (B) is 95: 5 to 5:95, and a coating composition obtained by mixing a curing agent with the resin. And a method for producing the above-mentioned coating resin shown in the following methods (1) to (3). In the presence of the resin (B), the monomers forming the resin (A) are polymerized. In the presence of the resin (A), the monomers forming the resin (B) are polymerized. [Effect] The coating resin of the present invention is compatible with a curing agent, The coating composition having excellent pigment dispersibility and the like, which contains the coating resin of the present invention as a main component, provides a coating film having excellent weather resistance, stain resistance, and the like. |
