摘要:
New hydroquinone ether compounds of formula I are described: ##STR1## wherein p is 1 or 2 and q is 0 or 1, provided that p+q is 1 or 2, R is a residue of formula II ##STR2## and R.sub.o, R.sub.oo, R.sub.1, R.sub.2, R.sub.3, Q, n and k are as defined in the specification.The new compounds are useful e.g. as stabilizers in photographic material.
