Abstract:
A compound of formulaA(B).sub.x, (I),wherein x is an integer 1, 2 or 3,A is the radical of a chromophore of the azo series, which radical contains x N atoms to which B groups are attached; at least one carbonyl group being adjacent at least one of said N atoms of said chromophore to which said B groups are attached,B is a group of formula ##STR36## or, when x is 2 or 3, B may also be hydrogen, with the proviso that at least one B is a group of formula (II) or (III) which is branched at the atom attached to said ##STR37## group, or a group of formula (IV); m, n and p are each independently of one another zero or 1,X is C.sub.2 -C.sub.14 alkylene or C.sub.2 -C.sub.8 alkenylene,Y is a group of --V--(CH.sub.2).sub.q --,Z is a group --V--(CH.sub.2).sub.r --,V is C.sub.3 -C.sub.6 cycloalkylene,q is an integer from 1 to 6, andr is an integer from zero to 6,R.sub.1 and R.sub.2 are each independently of the other hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, CN, NO.sub.2, unsubstituted phenyl or phenoxy or phenyl or phenoxy which are substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or halogen,Q is hydrogen, CN, Si(R.sub.1).sub.3 ;a group C(R.sub.5)(R.sub.6)(R.sub.7), wherein R.sub.5, R.sub.6 and R.sub.7 are each independently of one another hydrogen or halogen and at least one of R.sub.5, R.sub.6 and R.sub.7 is halogen;a group ##STR38## wherein R.sub.1 and R.sub.2 are as defined above; a group SO.sub.2 R.sub.8 or SR.sub.8, wherein R.sub.8 is C.sub.1 -C.sub.4 alkyl;a group CH(R.sub.9).sub.2, wherein R.sub.9 is unsubstituted phenyl or phenyl which is substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or halogen; or ##STR39## R.sub.3 and R.sub.4 are each independently of the other hydrogen, C.sub.1 -C.sub.18 alkyl, or a group ##STR40## wherein X, Y, R.sub.1, R.sub.2, m and n are as defined above, or R.sub.3 and R.sub.4, together with the linking nitrogen atom, form a pyrrolidinyl, piperidinyl or morpholinyl radical.
