Process for the preparation of a hydrophillic coating material having good sliding ability in wet condition

摘要

A process for forming and applying a hydrophilic coating which has very low friction in the moist state to a razor, in which a solution containing a water-soluble polymer, in particular polyvinylpyrrolidone, is applied and cured. The razor is made of plastic, such as polystyrene or ABS, or of metal provided with a device which reduces the friction. The invention proposes that the solution applied to the moulding comprises a water-soluble polymer, in particular poly-N-vinylpyrrolidone or a copolymer thereof, one or more free radical-polymerisable vinylmonomers and a photoinitiator which decomposes on irradiation to form free radicals, and that the applied solution is exposed to UV irradiation for curing.
