[PROBLEMS] To provide a rubber-like elastic body that is particularly excellent in weather resistance while being cured by moisture in the atmosphere and maintaining excellent workability and physical properties after curing, and at room temperature as well as at high temperatures in summer. Provided is a useful curable composition having a wide range of applications, such as a sealing material, an adhesive, and a paint, in which the plasticizer is prevented from transferring to the paint coated on the surface of the cured product to prevent surface contamination due to dust adhesion. A curable composition containing a crosslinkable silyl group-containing resin, a photoreactive acrylic and / or methacrylic polymer, and a curing catalyst. The photoreactive acrylic and / or methacrylic polymer is a number average molecular weight obtained by radical polymerization reaction of an ethylenically unsaturated compound mainly composed of an acrylic and / or methacrylic monomer at 50 ° C to 300 ° C. Is a polymerizable unsaturated group-containing acrylic and / or methacrylic polymer having a viscosity of 500 to 50,000, a Tg of 0 ° C. or lower, and a viscosity at 25 ° C. of 100,000 mPa · s or lower.
