<p>The composition contains a polymeric binder, a polymerisable compound and a photoinitiator combination consisting of an N- heterocyclic compound and a halogen compound of the general formulae I and II:
<IMAGE>
in which
X<1> denotes chlorine or bromine,
X<2> and X<3> are identical or different and X<1> denotes hydrogen or an alkyl group,
Y and Z are identical or different and X<1> denotes hydrogen, CN or (A)n-(B)n-D,
A is a phenylene group,
n is 0 or 1,
B is CO or SO2,
D is R, OR, NHR, NH2, NR2 or CX<1>X<2>X<3>,
R is an alkyl, cycloalkyl, aryl or heteroyl radical,
W is a 5- or 6-membered heterocyclic ring containing 1 to 3 hetero atoms which optionally carries substituents and a fused aromatic ring, and
m is 1 or 2.
A notable feature of the composition is its increased photosensitivity.</p> |
