Abstract
The present disclosure provides a coating composition for forming a coating that at least partially mobilizes in response to UV light, the composition comprising a monomer selected from acrylates, methacrylates and mixtures thereof, a cross-linking agent comprising two sub-units covalently bonded together, each sub-unit comprising an unsaturated group which is co-polymerisable with the monomer, wherein the two sub-units are adapted to dissociate in response to irradiation by UV light. The cross-linking agent may be present in the coating composition in an amount of less than 15 mol % of the total of the monomer and cross-linking agent.
