  • Patent number: 5331027
    Abstract: The lubricious hydrophilic coatings of the invention are significantly more lubricious when wet than when dry, are adherent to a variety of substrates, and are resistant to removal by wet abrasion. In one embodiment, the coatings include a hydrophilic polyolefin such as polyvinyl-pyrrolidone and a water-insoluble stabilizing polymer such as a cellulose ester. The coatings may also include an adherent polymer and a plasticizing agent. The coating may be applied by preparing a solution of the stabilizing polymer and a solution of the hydrophilic polyolefin, and coating the substrate first in one then the other. Alternatively, both the stabilizing and hydrophilic polymers may be dissolved in a single solvent system and applied to the substrate in a single step. In another embodiment, only a solution of a hydrophilic polyolefin is applied directly to the substrate.
