主权项

1. A medical device comprising a cured coating, wherein the cured coating comprises at least two layers comprising an inner layer and an outer layer, wherein the inner layer is a primer layer comprising a supporting network and formed by curing a primer layer formulation comprising a supporting polymer, and wherein the outer layer is a functional layer formed by curing a functional layer formulation, the functional layer formulation comprising:
(A) at least one multifunctional polymerizable compound according to formula (1): wherein G is a polymer and is a residue of a hydrophilic polyfunctional compound having at least n functional groups; each R1 and each R2 independently represents hydrogen or a group selected from substituted and unsubstituted hydrocarbons which optionally contain one or more heteroatoms; and n is an integer having a value of 2-100.
