Claims23
An antimicrobial surface coating composition comprising a UV curable compound of formula (I)
- wherein n is 3 or 4;
- R1 and R2 are independently methyl, ethyl, n-propyl or i-propyl;
- Z is
- wherein m is selected from the group consisting of 12, 13, 14, 15, 16, 17 and 18, or
- wherein R3, R4 and R5 are independently hydrogen, C1-C6 linear or branched alkyl or C6-C10 aryl;
- and
- X is a halogen selected from the group consisting of chloro, bromo and iodo;
- and a carrier, wherein said carrier is a mixture of water and an alcohol, wherein said composition is UV curable upon application to said surface.
