摘要： Provided are a coating composition containing a silicon atom-containing resin and a defoaming agent, a coating film formed from the same, an in-water structure and a ship having the coating film. In the coating composition, the silicon atom-containing resin includes a constituent unit (A) derived from a monomer (a) having at least one kind of silicon atom-containing group selected from the group consisting of a group represented by the following formula (I), a group represented by the following formula (II), a group represented by the following formula (III), and a group represented by the following formula (IV), the monomer (a) has a molecular weight of greater than or equal to 400 and less than or equal to 2500, and the content of the defoaming agent is greater than or equal to 0.7 parts by mass and less than or equal to 24 parts by mass with respect to 100 parts by mass of the silicon atom-containing resin.

摘要： Provided are a coating composition containing a silicon atom-containing resin and an anti-sagging agent, a coating film formed from the same, an in-water structure and a ship including the coating film. In the coating composition, the silicon atom-containing resin includes a constituent unit (A) derived from a monomer (a) having at least one kind of silicon atom-containing group selected from the group consisting of a group represented by the following formula (I), a group represented by the following formula (II), a group represented by the following formula (III), and a group represented by the following formula (IV), the monomer (a) has a molecular weight of greater than or equal to 400 and less than or equal to 2500, and the content of the anti-sagging agent is greater than or equal to 0.7 parts by mass and less than or equal to 3.6 parts by mass with respect to 100 parts by mass of the silicon atom-containing resin.
