ABSTRACT:
Coating composition suitable for treating a surface so as to provide a water-erodible coating thereon, which composition comprises at least one erodible polymer comprising one or more hydrolysable groups selected from sulphonate esters and sulfphonate esters which in an aqueous environment will generate by hydrolysis corresponding polymer-bound acid groups. The erodible polymers are described in detail and a method of treating surfaces using the composition is described.
