Figure 1 : Measurement of contact angles i-H o CJ (57) Abstract: An antifouling coating composition for application to a surface described. is The coating comprises a block copoly­ mer binder. The copolymer includes at least two polymer blocks A and B, at least 50% of the monomer units in block A being monomer residues of ethylenically unsaturated carboxylic, sulfonic or phosphonic acids. The monomer residues have silyl ester side groups containing at least 3 silicon atoms in the silyl group. A substrate coated with the coating, a block copolymer binder and a pro - cess for producing a block copolymer binder are also described.
