Compositions which are reticulable by means of photopolymerisation.

摘要

The mixtures crosslinkable by photopolymerisation are based on binders, photopolymerisable monomers compatible therewith, photoinitiators and inhibitors of thermally initiated polymerisation and contain, as the binder, polymers of the formula I

in which the variables and the indices are defined as follows:
Pol = radical of a block copolymer prepared by sequential anionic polymerisation of conjugated dienes and vinylaromatics, R<1> = a vicinal alkanediyl group,
R<2> = a divalent hydrocarbon group having 2 to 20 carbon atoms,
X<(-)> = an acid anion group,
M = a metal cation, metal cation complex or cation of an amine,
a = an integer from 1 to 10 and
n = an integer from 1 to 10.
