Abstract
Abstract Surface-coating compositions that have improved resistance to attack by bacteria and fungi contain 0.1 percent to 3 percent by weight of a biocidal component that comprises a polyoxymethyleneoxazolidine selected from the group consisting of A. COMPOUNDS HAVING THE STRUCTURAL FORMULA WHEREIN EACH R represents hydrogen, alkyl of 1 to 6 carbon atoms, phenyl, halophenyl, or -(CH2O)mCH2OH; m represents a number in the range of 0 to 2; and n represents a number in the range of 1 to 4; B. COMPOUNDS HAVING THE STRUCTURAL FORMULA D R A W I N G WHEREIN EACH R'' represents alkyl of 1 to 6 carbon atoms or CH2OH and R and n have the aforementioned significance; and C. MIXTURES THEREOF. The polyoxymethyleneoxazolidines preferably contain a total of not more than six oxymethylene units (-CH2O-) in one or more ring substituents.
