CONSTITUTION:An inclusion compd. of an isothiazolone compd. with 1,1,6,6- tetraphenyl-2,4-hyxadiyne-1,6-diol (hereinafter referred to as 'TPH') or 1,1-di(2,4- dimethylphenyl)-2-propyn-1-ol (hereinafter referred to as 'DMP') is used as an antifouling gent for underwater antifouling paint. The inclusion compd. is blended in an amt. of 0.5-50wt% based on the total amt. of the paint compsn.
