[PROBLEMS] To provide a coating film or coating film that is useful as a material for paints and coating agents that are excellent in water repellency, oil repellency, releasability, transferability, substrate adhesion and stain resistance. Providing a siloxane group-containing polymer and a cured coating thereof. A polysiloxane compound having an ethylenically unsaturated group at one end via a hydroxyurethane bond represented by the following general formula (1) is homopolymerized or copolymerized with another polymerizable monomer. A polysiloxane group-containing polymer obtained and having a weight average molecular weight of 10,000 to 1,000,000. [Selection figure] None |
