## Abstract

An antifouling composition for coating fishnets consisting essentially of (A) at least one phenol compound represented by the formula: ##STR1## or the formula: ##STR2## (in which Y is hydrogen atom or hydroxyl group; ##STR3## m is 0 or 1; n is an integer of 1-5; R is a linear or branched alkyl having 4 to 21 carbon atoms), (B) at least one water-repellent organic compound selected from silicone oil, petroleum wax and liquid paraffins, and (C) at least one antifouling agent selected from fluorodichloromethyl thiophthalimide, dimethylphenyl fluorodichloromethyl thiosulfamide and dichlorophenyl dimethyl urea, the amount of said (C) being 0.5-20 wt % of the total of (A)+(B)+(C). The present antifouling composition is specifically effective for the prevention of attachment, and proliferation of noxious aquatic organisms including both of an animal and botanical nature.

## Claims

### Claim 1

An antifouling composition consisting essentially of
(A) at least one phenol compound represented by the formula: ##STR10## group; m is 0 or 1 ; Y is hydrogen atom or hydroxyl group; and n is an integer of 1 to 5) or the formula: ##STR11## in which R is a linear or branched alkyl having 4 to 21 carbon atoms and n is an integer of 1-5.
(B) at least one water-repellent organic compound selected from group consisting of silicone oil, petroleum wax, and liquid paraffin, and
(C) at least one antifouling agent selected from the group consisting of fluorodichloromethyl thiophthalimide, dimethyl phenyl fluorodichloromethyl thiosulfamide and dichlorophenyl dimethyl urea, the amount of said antifouling agent being 1-12% by weight of the total of said (A)+(B)+(C).
