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-knows applications for free radical polymerizable compositions. They are especially useful for the formation of imageable elements useful as lithographic printing plate precursors.

The present invention relates to a process for producing a composite material. A radiation-curable water-compatible composition is applied to the surface of a substrate having a high water content, wherein the composition comprises at least one radiation-polymerisable monomer and/or oligomer, whereby the composition wets the surface of the substrate. The composition on the substrate is then irradiated to produce the composite material. Optionally the monomer and/or oligomer is reacted with a phosphite or a triorganophosphine prior to the irradiation. These compositions may also be applied to low water content substrates.
