Long-release germicidal compsns. contg. 5-methyl-S-triazolo (3,4-b) benzothiazole (A), isocyanate cpds. (I) (n=0-8) and acrylpolyol cpds. (II) (R1=H, Me; R2=H, OH, (un)substd. alkyl) were prepd.. Thus, a mixt. of (A) 45, alkylbenzenesulfonate-Na 10, polyvinylalcohol 20, bentonite 100, clay 825 parts and appropricate amt. of H2O was granulated to give granules with < 0.8mm and dried at 80≦̸C using a fluid-dryer. The dried granules were sieved with a screen of 16-32 mesh. 900 part sieved granule was coated with 100 part tolylenediisocyanate using a mixer to give a granular compsn. contg. 4 wt.% A.
