<p>A method of producing an article with a coating having friction-reducing properties in wet condition, said coating comprising a binder (a), a hydrophilic polymer (b), as well as, if desired, an osmolality-increasing compound (c), whereby a dispersion is produced from (a) a binder in form of a hardenable prepolymer of a molecular weight of at least 200, (b) one or more hydrophilic polymers, (c) if desired, an osmolality-increasing compound, and (d) a solvent or a mixture of solvents, in which (a) is substantially insoluble, applying said dispersion onto the article, removing the solvent or a portion thereof, and hardening the binder, as well as a coating material for this purpose. A durable coating is obtained having good slide properties even after a long stay in an aqueous environment, such as within a body cavity.</p> |
