The use of hydroxyphenylvinylthiazoles of formula
##STR1##
wherein
R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each independently of the others
hydrogen; halogen; hydroxy, C.sub.1 -C.sub.16 -alkyl, C.sub.1 -C.sub.16
alkoxy, phenyl; phenyl-C.sub.1 -C.sub.3 alkyl; C.sub.6 -C.sub.10 aryloxy,
amino, mono-C.sub.1 -C.sub.5 alkyl-amino, di-C.sub.1 -C.sub.5 alkylamino
or -NO.sub.2 ; wherein at least one of the radicals R.sub.1, R.sub.2,
R.sub.3 and R.sub.4 is hydroxy;
R.sub.5 is C.sub.1 -C.sub.5 alkyl; C.sub.1 -C.sub.5 alkoxy; or
unsubstituted or halo-, C.sub.1 -C.sub.5 alkyl-, C.sub.1 -C.sub.5 alkoxy-,
hydroxy- or pyrrolidinyl-substituted phenyl; as microbicidal active
ingredients is described. The compounds exhibit a pronounced action
against pathogenic gram-positive and gram-negative bacteria, and also
against yeasts and moulds. Accordingly, they are suitable for the
antimicrobial treatment, especially the preservation and disinfection, of
surfaces.
L'uso dei hydroxyphenylvinylthiazoles del ## del ## STR1 di formula in cui R.sub.1, R.sub.2, R.sub.3 e R.sub.4 sono indipendentemente ciascuno dagli altri idrogeno; alogeno; idrossilato, C.sub.1 - C.sub.16 - alchile, C.sub.1 - C.sub.16 alcossi, fenilico; phenyl-C.sub.1 - Alchile C.sub.3; C.sub.6 - Aryloxy C.sub.10, amminico, mono-C.sub.1 - C.sub.5 alchile-amminico, di-C.sub.1 - alkylamino C.sub.5 o - NO.sub.2; in cui almeno uno dei radicali R.sub.1, R.sub.2, R.sub.3 e R.sub.4 è idrossilato; R.sub.5 è C.sub.1 - alchile C.sub.5; C.sub.1 - C.sub.5 alcossi; o non sostituito o guidacarta -, C.sub.1 - alchile C.sub.5 -, C.sub.1 - C.sub.5 alcossi -, fenile idrossilato o pyrrolidinyl-sostituito; come microbicida gli ingredienti attivi è descritto. I residui esibiscono un'azione pronounced contro i batteri gram-positivi e gram-negativi patogeni ed anche contro i lieviti e le muffe. Di conseguenza, sono adatti a trattamento antimicrobico, particolarmente a conservazione ed a disinfezione, delle superfici.
