The invention relates to the use of an antimicrobial agent for the biocidal equipping of biocides based on polymers whose molecules have at least one nitrogen atom with a free electron pair and are coordinately bonded to a metal complex via the lone pair of electrons of the nitrogen atom. In order to achieve a high degree of insolubility without loss of the biocidal effect, it is proposed that the metal complex phthalocyanines with copper, zinc, tin, iron or cobalt as the central atom, porphyrins with magnesium, copper or iron as the central atom or corroles with copper, zinc, iron, Gold, silver, vanadium, molybdenum or cobalt can be used as the central atom. |
