2 . A process for protecting industrial materials against attack by fungi and algae comprising applying thereto the composition according to claim 1 .
3 . A method for protecting industrial materials against attack by fungi and algae, comprising mixing or treating the industrial materials with a composition according to claim 1 .
4 . A process for preparing the composition according to claim 1 , comprising mixing together the o-phenylphenol, the 2-methyl-2H-isothiazol-3-one, and the 1,2-dibromo-2,4-dicyanobutane.
5 . The composition according to claim 1 , wherein the ratio of o-phenylphenol to 2-methyl-2H-isothiazol-3-one and 1,2-dibromo-2,4-dicyanobutane is between 99.9:0.1 and 50:50 by weight.
6 . The microbicidal composition according to claim 1 , further comprising at least one extender, surfactant, tackifier, and/or mineral and/or vegetable oil.
7 . A process for protecting industrial materials against attack by fungi and algae comprising applying thereto the composition according to claim 6 .
8 . A method for protecting industrial materials against attack by fungi and algae, comprising mixing or treating the industrial materials with a composition according to claim 6 .
9 . A process for preparing the composition according to claim 6 , comprising mixing together the o-phenylphenol, the 2-methyl-2H-isothiazol-3-one, the 1,2-dibromo-2,4-dicyanobutane of the synergistic mixture of microbicidally active compounds and the at least one extender, surfactant, tackifier, and/or mineral and/or vegetable oil.
10 . The composition according to claim 6 , wherein the ratio of o-phenylphenol to 2-methyl-2H-isothiazol-3-one, 1,2-dibromo-2,4-dicyanobutane of the synergistic mixture of microbicidally active compounds, and the at least one extender, surfactant, tackifier, and/or mineral and/or vegetable oil is between 99.9:0.1 and 50:50 by weight.
