Abstract
An antifouling coating film excellent in film solubility and antifouling performance; an antifouling coating material forming the film; a submerged structure having the antifouling coating film; and an antifouling method. The antifouling coating material comprises a polymer having specific organosilicon ester groups and a polymer having specific metal carboxylate groups. The antifouling coating film is formed from the antifouling coating material. The submerged structure has the antifouling coating film. The antifouling method comprises applying the antifouling coating material.
Claims6
Antifouling paint which comprises:
- (A) one or more kinds of organosilyl-ester-group-containing polymers having at least one kind of an organosilyl ester group in each of the polymer molecules, where the triorganosilyl ester group is represented by the general formula (1):
- 3
- wherein in the formula (1) R1, R2 and R3 are groups each independently selected from the group consisting of the alkyl groups, cycloalkyl groups, aryl groups and aralkyl groups having a carbon number of 1-18, and are the same or different from each other with the proviso that the carbon number of at least one of the three groups R1, R2 and R3 is not less than 3, and
- (B) one or more kinds of metal-caboxylate-group-containing polymers having at least one kind of an metal carboxylate group in each of the polymer molecules, where the metal carboxylate group is represented by the general formula (2):
- —COO—M—X (2)
- wherein in the formula (2) M is a metal selected from the group consisting of Cu, Zn, Ca and Mg, and X is an organic acid residue or a hydroxy group.
