Abstract: Paints are protected against attack by fungi and bacteria by applying to the surface of said material or incorporating therein a bismuth compound of the formula R13BiX2 or RnBiX3-n, wherein n is 1 or 2, X is a monovalent anionic atom or group of two X's when taken together represent a divalent anionic atom or group, R1 is a substituted or unsubstituted aryl group and R is a substituted or unsubstituted alkyl, cyclo-alkyl, alkenyl or aryl group.  X may be a halogen, e.g. F, Br, Cl, oxygen, sulphur, carboxylate, phenoxide, mercapto propionate; hydroxybenzoate, amino benzoate, chloroacetate, tartrate isooctyl mercapto-acetate methacrylate, acrylate, thiocyanate, alkoxide, hydroxide, acetate, salicylate, benzoate, or cyanide group. R11 may be a phenyl, chlorophenyl, tolyl alkoxy phenyl, nitrophenyl or xylyl group.  Other microbicides, e.g. quaternary ammonium salts such as lauryl dimethyl benzy ammonium chloride, triorganotin compounds, pentachlorophenol, copper-8-quinolisolate, bisphenols, o-phenyl phenol, brominated salicylanilides or zinc dialkyl dithiocarbanate.  The bismuth compounds may be formulated as dusts, solutions, suspensions, aerosols and emulsions containing if desired nonionic, cationic or anionic surfactants.  In the examples, a paint comprising TiO2/CaSo4, calcium carbonate, magnesium silicate, ester gum solution, bodied linseed oil, mineral spirits, cobalt naphthenate, lead naphthenate and phenyl bismuth dilauryl mercaptide is described.ALSO:Paper mill and oil recovery waters are protected against attack by fungi and bacteria by applying to the surface of said material or incorporating therein a bismuth compound of the formula R13BiX2 or RnBiX3- n, wherein n is 1 or 2, X is a monovalent anionic atom or group or two X's when taken together represent a divalent anionic atom or group, R1 is a substituted or unsubstituted aryl group and R is a substituted or unsubstituted alkyl, cycloalkyl, alkenyl or aryl group.  X may be a halogen, e.g. F, BrCl, oxygen, sulphur, carboxylate, phenoxide, mercapto propionate, hydroxybenzoate, amino benzoate, chloroacetate, tartrate iso-octyl mercapto-acetate, methacrylate, acrylate, thiocyanate, alkoxide, hydroxide, acetate, salicylate, benzoate, or cyanide group. R11 may be a phenyl, chlorophenyl, tolyl alkoxy phenyl, nitrophenyl or xylyl group. Other microbicides, e.g. quaternary ammonium salts such as lauryl dimethyl benzy ammonium chloride, triorganotin compounds, pentachlorophonol, copper-8-quinolisolate, bisphenols, o-phenyl phenol, brominated salicylanilides or zinc dialkyl dithiocarbamate. The bismuth compounds may be formulated as dusts, solutions, suspensions, aerosols and emulsions containing if desired nonionic, cationic or anionic surfactants.ALSO:Synthetic resin compositions are protected against attack by fungi and bacteria by applying to the surface of said material or incorporating therein a bismuth compound of the formula R13BiX2 or RnBiX3- n, wherein n is 1 or 2, X is a monovalent anionic atom or group or two X's when taken together represent a divalent anionic atom or group, R1 is a substituted or unsubstituted aryl group and R is a substituted or unsubstituted alkyl, cyclo-alkyl, alkenyl or aryl group.  The Examples describe compositions containing (1) TiO2 aluminium silicate, talc, a methyl methacrylate-butyl methacrylate copolymer mineral spirits, and dibutyl bismuth acetate (5) TiO2, bentonite, tricresyl phosphite a vinylchloride-vinyl acetate copolymer, triphenyl bismuth chloride and phenyl bismuth chloride toluene and methyl isobutyl ketone, and (23)-(26) polyvinyl chloride, triphenyl-bismuth dichloride, dioctyl phthalate and stearic acid.ALSO:Materials are protected against attack by fungi and bacteria by applying to the surface of said material or incorporating therein a bismuth compound of the formula R 1/3 B1X2 or RnBiX3-n, wherein n is 1 or 2, X is a manovalent anionic atom or group or two X's when taken together represent a divalent anionic atom or group, R1 is a substituted or unsubstituted aryl group and R is a substituted or unsubstituted alkyl, cyclo-alkyl, alkenyl or aryl group.  X may be a halogen e.g. F, Br, Cl oxygen, sulphur, carboxylate, phenoxide, mercapto propionate; hydroxy benzoale, amino benzoate, chloroacetate, tatrate isochylmercaptoacetate methacrylate, acrylate, thiocyanate, alkoxide, hydroxide, acetate, salicylate, benzoate, or cyanide group.  R1, may be a phenyl, chlorophenyl, tolyl alkoxyphenyl nitrophenyl or xylyl group.  Other microbicides e.g. quaternary ammonium salts such as lauryl dimethyl benzyl ammonium chloride, triorganotin compounds, pentachlorophenol, copper-8-quinolinolate, bisphenols, o-phenyl phenol, brominated salicylanilides or zinc dialkyl dithiocarbanate. The bismuth compounds may be formulated as dusts, solutions, suspensions, aerosols and emulsions containing if desired nonionic, cationic or anionic surfactants.  The bismuth compounds may be used to treat materials such as textiles, paper paper mill and oil recovery waters, adhesives, plants, synthetic resins and paints.  In the examples paints comprising T1O2, aluminium silicate, talc, methyl methacrylatebutyl methacrylate copolymer mineral spirits, and dibutyl bismuth acetate-Ex5, T1O2, bentonite, tricresyl phosphite vinylchloride-vinyl acetate copolymer, triphenyl bismuth chloride and phenyl bismuth chloride-Ex6 and T1O2/CaSO4, calcium carbonate, magnesium silicate ester gum solution, bodies linseed oil, mineral spirits, cobalt naphthenate, lead naphthenate and phenyl bismuth dilauryl mercaptide are described.
