A composition comprising:n (i) an anti-microbial agent; and (ii) an acidic co-polymer of the Formula (1) nn nwherein:n [A] is of Formula (9), nn n n n n n n n n n n n [B] is of Formula (10), n n n n n n n n n n n n n n n n and [C] is of Formula (12), n n n n n nwherein:n [X] is of Formula (11), nn nwherein [A], [B] and [C] may occur in any order;n T is an optionally substituted substituent; L and G each independently is an optionally substituted linking group; R 1 , R 2 and R 3 are each independently H, optionally substituted C 1-20 -alkyl or optionally substituted C 3-20 -cycloalkyl; R 4 and R 5 are each independently H or C 1-4 -alkyl; q is 15 to 1000; p is 3 to 50; J is an optionally substituted hydrocarbyl, group; F is an acidic substituent; b is 0, 1, or 2; m is 0 to 350; n is 1 to 75; v is 1 to 100; and w is 1 to 4; provided that at least one of R 4 and R 5 is H and provided that R 1 , R 2 , R 3 , T, L, J and G do not contain a basic group; and wherein the pka value of the acidic substituent F on the monomer from which [C] is derived is less than 5.5. |
