A copolymer comprising (i) a plurality of ethylenic moieties A having a structure according to the following formula:
wherein R2 and R3 independently represent hydrogen, a halogen or an optionally substituted linear, branched or cyclic alk(en)yl group, or an optionally substituted aromatic or heteroaromatic, and (ii) a plurality of acetal moieties B having a structure according to the following formula:
wherein L1 represents a divalent linking group; x = 0 or 1 and R1 represents an optionally substituted aromatic or heteroaromatic group including at least one hydroxyl group, and (iii) a plurality of acetal moieties C and/or moieties D which include a structural moiety comprising a chromophoric group having its main absorption in the infrared region.
