A polymer comprising repeat units of the general formulae (I), (II) and (III):
- or salts thereof,
- wherein:
- the repeat unit of general formula (I) is comprised in the polymer with a number of m units, the repeat unit of general formula (II) is comprised in the polymer with a number of o units and repeat unit of general formula (III) is comprised in the polymer with a number of p units, wherein each of m, o and p is an independently selected integer from about 3 to about 400 and wherein the sum of m+o+p is selected in the range from about 10 to about 10,000,
- R1 in repeat units (I) to (III) is H or methyl,
- R2 in repeat unit (II) is an aliphatic moiety with a main chain of about 3 to about 30 carbon atoms and 0 to about 3 heteroatoms selected from the group N, 0, S, Se and Si, and,
- R3 in repeat unit (III) is an optionally substituted dye molecule.
