<p>An inorganic substrate with two or more coating layers is provided. The first coating layer is attached to the inorganic substrate and includes the polymeric reaction product formed upon hydrolysis of a silane compound having at least two tri(C1-C3)alkoxysilyl groups. The second and subsequent coating layers include at least one hydrophilic polymer and at least one photoactivatable cross-linking agent. The inorganic substrate can be a medical device suitable for insertion into the body of a mammal. The coatings are tenacious and not easily removed from the inorganic substrate by abrasion.</p> |
