Abstract

A method of forming a polymer layer on a support surface by the use of a coating agent and polymerizable compounds. The coating agent provides photoreactive groups adapted to attach the agent to the surface, as well as photoreactive groups adapted to remain unattached to the surface, and thus serve as photoinitiators for the activation of polymerizable compounds in order to form a polymer layer thereon. Also provided are coating agents, per se, as well as a method of using such agents and the resultant surfaces and devices fabricated therefrom.
