The present invention relates to a method of protecting marine surfaces, comprising coating said marine surface with an antifouling paint comprising: a) toxicant, organic solvent and b) a film-forming water-insoluble, sea water-erodible substantially organotin free polymeric binder, said polymeric binder having recurring groups represented by the formula wherein B is the residue of an ethylenically unsaturated monomer, X is H or CH3, R is selected from the group consisting of: (i) or wherein Z is NO2, halogen or CN; (ii) -(CH2)nY wherein n is an integer from 1 to 4; and Y is selected from the group consisting of , -OR''', -SR''', , and wherein R' is C1 to C4 primary, secondary or tertiary alkyl, R" is H or R', R''' is alkyl or an aryl; (iii) a quaternized amino alkyl represented by the formula where Y is Br, Cl or I, R', R" and R''' are the same or different C1 to C18 alkyls; (iv) haloalkyl having at least one trihalomethyl group, where the halogen is Br, F or C1 and the alkyl has at least two carbons; (v) -(CH2)n?-R'''' where n is 1 or 2 and R'''' is R' or a phenyl group; (vi) -Si(R''')3 or -Si(OR''')3, and R''' is alkyl or an aryl. |
