ABSTRACT:
Hydrazide functionalized 2-hydroxybenzophenone ultraviolet light and heat stabilizers and derivatives are disclosed having the general formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, X, Y, Z, all substituents thereof, and n are set forth in the Summary of the Invention. Y--N(R.sup.6)--Z is the hydrazide or derivative group and --X--R.sup.5 -- links the hydrazide group to an aromatic nucleus of the optionally substituted benzophenone group. Derivatives are, for example, acyl hydrazides, diacyl hydrazides (including imides), hydrazones and alkyl hydrazides. The compounds are useful as ultraviolet light absorbers and heat stabilizers for plastics.
