Novel methods have been described for achieving antimicrobial, preservative and / or microbial adhesion inhibitory effects for protection in articles and / or materials or for protection on surfaces of articles and / or materials. The novel method comprises applying to the article and / or material a salicylic acid compound of formula (I), or an adduct or salt thereof. <Formula I> Where One of A and A 'is a residue of formula -NH-CO-R 1 (I ') The other is hydrogen; R 1 is C 1 -C 22 alkyl, C 3 -C 12 cycloalkyl, O and / or NR 5 is interposed a C 3 -C 12 cycloalkyl, C 4 -C 12 aryl, C 5 -C 18 aryl and ; R 2 is OR 3 or NHR 4 ; R 3 and R 4 are H, C 1 -C 22 alkyl, C 3 -C 12 cycloalkyl, C 3 -C 12 cycloalkyl, C 4 -C 12 aryl, C 5 -interrupted by O and / or NR 5. C 18 arylalkyl; R 5 is H or C 1 -C 8 alkyl; Wherein each aryl moiety is unsubstituted or C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 1 -C 4 acyl, C 1 -C 4 acyloxy, C 1 -C 4 acylamino, CF 3 , OH, amino, halogen. |
