Abstract: The present invention relates to a process for applying an optical coating to a substrate comprising the steps of (a) preparing an optical coating formulation comprising a solvent component and a film forming component; (b) using a die coater to form a coated substrate by applying the optical coating to a substrate, where the applied optical coating forms a wet film thereon having a thickness from 8 ?m to 100 ?m; (c) drying the coated substrate, where the coated substrate is in a substantially horizontal plane thereby converting the wet film to a dry film having a thickness of less than 1 ?m. The optical coating formulation comprises greater than 0.3 wt % to no more than 10 wt % solids relative to the total weight of the optical coating formulation. The coated substrate may be optionally cured.

Abstract: The invention relates to a coating material suitable for providing a substrate with an anti-biofouling coating, the coating material comprising a macromolecule comprising: (A) a macromolecular scaffold comprising a reactive group capable of undergoing a Michael type reaction between a Michael type acceptor group and a Michael type donor group, (B) at least one functional moiety attached to the macromolecular scaffold, said at least one functional moiety comprising a hydrophilic moiety, wherein the functional moiety is derivable from a Michael type reaction, involving the reactive group on the macromolecular scaffold and a reactive hydrophilic moiety and (C) at least one moiety capable of crosslinking the coating material.
