41827031, Jan 8, 1980

Filed:

Jan 9, 1978

Appl. No.:

5/867846

Inventors:

Gether Irick - Kingsport TN
James C. Ownby - Kingsport TN
Richard H. S. Wang - Kingsport TN

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

C08K 545
C08K 546
C07D41312
C07D41712

US Classification:

260 458RW

Abstract:

The invention relates to biheterocyclic compounds which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing a stabilizing amount of the biheterocyclic composition to prevent such degradation. These stabilizers are effective in the presence of other additives commonly employed in polymeric compositions including, for example, pigments, colorants, fillers, reinforcing agents and the like. These ultraviolet stabilizers may also be incorporated into the organic compositions in the polymer melt or dissolved in the polymer dope, coated on the exterior of the molded article, film or extruded fiber.

Abstract:

The invention relates to heterocyclic benzoate compounds which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing an amount of a heterocyclic benzoate composition to prevent such degradation. These stabilizers are effective in the presence of other additives commonly employed in polymeric compositions including, for example, pigments, colorants, fillers, reinforcing agents and the like. These ultraviolet stabilizers may be incorporated into the organic compositions such as polymers by adding to the polymer melt or dissolved in the polymer dope, coated on the exterior of the shaped or molded article, film or extruded fiber.
