Abstract: The present invention relates to the field of security documents and their protection against counterfeit and illegal reproduction and relates to the field of intaglio printing processes for the printing of said security documents. In particular, the present invention relates to radiation curable intaglio inks suitable for intaglio printing a pattern or image, wherein said intaglio printing comprises wiping off ink excess with a polymeric wiping cylinder and cleaning said cylinder with an alkaline aqueous wiping solution, The disclosed radiation curable intaglio inks comprise one or more radiation curable compounds, wherein at least one of said one or more radiation curable compounds is a fatty acid polyester (meth)acrylate oligomer; one or more photoinitiators; and a high molecular weight acid modified alkyd surfactant and/or an alkylarene sulfonic acid surfactant; one or more fillers or extenders.

Abstract: Process for the preparation of a hydrocarbon polymer comprising two end groups having 2-oxo-1,3-dioxolan-4-yl final parts by ring opening metathesis in the presence of a metathesis catalyst, of a chain transfer agent comprising a carbonate ring and of a compound of formula comprising at least one C6-C16 ring having a carbon-carbon double bond. Hydrocarbon polymer capable of being obtained by this process. Process for the preparation of polyurethanes by reaction of this polymer and of a compound comprising at least one amine group, and polyurethanes thus obtained.
