Vinyl ether compounds having additional functional groups other than vinyl ether groups and the use thereof in the formulation of curable compositions

Claim 1

A radiation polymerizable composition comprising: a compound having at least one vinyl ether group which also contains in the molecule at least one further functional group, which compound is represented by the formula ##STR57## wherein the symbols used in the above formula and in the formulae below have the following definitions: A is a z-valent radical selected from the radicals of the following formulae (1), (2), (3) and (4) ##STR58## [D] is a group of the formula ##STR59## [E] is a C 1 - or a C 2 -alkylene group; R 0 is a hydrogen atom or a methyl group; R 1 is a z-valent radical selected from aliphatic, cycloaliphatic, aromatic, aliphatic-aromatic and aliphatic-cycloaliphatic radicals and polyoxyalkylene radicals and is unsubstituted or may have one or more substituents which in the case of an aliphatic radical R 1 are selected from C 1 -C 4 alkoxy and halogen substituents; and in the case of other types of radical R l are selected from C 1 -C 4 alkyl, C 1 -C 4 alkoxy and halogen substituents; R 2 is a radical selected from the radicals of the formulae ##STR60## R 4 is a group selected from the groups of the formulae ##STR61## R 5 is a group selected from the groups of the formulae ##STR62## R 6 is a (2·z)-valent organic group which, together with the carbon atoms C.sup.α and C.sup.β of each of the z groups of the formula ##STR63## in a radical of formula (2), forms a cycloaliphatic ring having at least 5 carbon atoms; R 14 and R 15 are each a hydrogen atom or, when [E] is a C 2 alkylene group, are each a hydrogen atom or together form a methylene group; i is an integer from 0 to 20; m is an integer from 1 to 20; s is an integer from 2 to 10; t is an integer from 0 to 10; u in the individual units of the formula ##STR64## in formula (5) are independently of one another an integer from 1 to 20; v is an integer from 0 to 4; x and y are independently of one another an integer from 2 to 20, and z is the number 1 or 2; at least one radically or cationically polymerisable compound that is different therefrom selected from the group consisting of mono-, di-, and poly(meth)acrylates, vinyl compounds, and di- and polyfunctional epoxy compounds; and at least one photoinitiator for the cross-linking of the compounds.
