Abstract: An ultraviolet light absorbing material that resists blooming and migration is made up of a polyurethane or polyurea polymer and an amide functional ultraviolet light absorbing compound, wherein the polymer and the amide functional ultraviolet light absorbing compound are hydrogen bonded to one another. Polymeric films that contain a polymeric matrix and the ultraviolet light absorbing material are useful as the top layer in multilayer constructions such as retroreflective sheetings and conformable marking sheets.

Abstract: Oligomeric materials contain ultraviolet light absorbing compounds that are covalently bound to the oligomer backbone through an ester or amide linkage. These ultraviolet light absorbing oligomers may be combined with polymers such as polyolefins to provide protection against the harmful effects of ultraviolet light.

Abstract: This invention relates to the synthesis of N-(monosubstituted)dithiooxamides by the transamination of dithiooxamide. Preferred methods, according to the present invention, take advantage of the discovery that yields of N-(monosubstituted)dithiooxamides can be improved in the Wallach Reaction by: controlling the temperature of the reaction mixture; optimizing the initial concentration of the reactants; adding an effective amount of acid in the quenching or processing procedure; and/or, optionally, adding an effective amount of certain nitrogen bases to the reaction mixture.
