QHB-Modified free radical polymerizable compounds and free radical polymerizable
compositions that comprise these compounds are disclosed. A QBH-modified free radical
polymerizable compound has at least one moiety that comprises at least one free
radical polymerizable group; a supporting backbone, and at least one and preferably
at least two moieties capable of forming four or more, typically four, hydrogen
bonds with similar or complementary units on other molecules or portions of molecules.
Free radical polymerizable compositions that contain these compounds may be used
in any of the well-known applications for free radical polymerizable compositions.
They are especially useful for the formation of imageable elements useful as lithographic
printing plate precursors.
