  • Publication number: 20230159788
    Abstract: The present invention provides a coating composition which is capable of forming a coating film that has excellent adhesion to a base material. The coating composition contains: an isocyanate-reactive group-containing resin (A); a polyisocyanate compound (B); and a hydroxyl group-containing aromatic compound (C) having a number average molecular mass of 100-1,000. The isocyanate-reactive group-containing resin (A) in the coating composition contains at least one type of resin selected from a hydroxyl group-containing resin (A1) and an amino group-containing resin (A2).

  • Patent number: 11365281
    Abstract: A coating composition includes a blocked urethane elastomer (A) containing a terminal isocyanate group blocked with an oxime compound and having a number average molecular weight of 800 to 5,000, an aromatic diamine compound (B) containing an electron-donating group, and an amide compound (C). An equivalent ratio (amino group/isocyanate group) of the amino group of the aromatic diamine compound (B) to the isocyanate group of the blocked urethane elastomer (A) is within a range of 1.0 to 2.0. A solid content of the amide compound (C) is within a range of 0.5 mass % to 5 mass % based on a total solid content of the blocked urethane elastomer (A) and the aromatic diamine compound (B).
