  • Patent number: 4503177
    Abstract: The stabilization of selected photochromic compounds, selected from certain fulgides and fulgimides, is made possible by associating with such compounds a clay mineral having an expanding crystal lattice, which can stabilize a selected photochromic compound in a higher-energy colored form. The stabilized photochromic compound may be one included in a coating composition, such as a paper coating composition, or may constitute or be incorporated in a filler for a papermaking furnish or for a plastics material. The stabilizer serves to maintain the photochromic compound in its higher-energy colored state or one of its higher-energy colored states, thereby tending to prevent deterioration of color as the photochromic compound converts to an uncolored or weakly colored lower-energy state.

  • Patent number: 4446262
    Abstract: A photo-stabilized polymer composition comprising a polymer and as an ultraviolet absorber, at least one compound selected from specific cyclic imino esters having an aromatic nucleus, two carbon atoms of which forms a part of the imino ester ring, such as 2,2'-p-phenylene-bis(3,1-benzoxazin-4-one), or 2,8-dimethyl-4H,6H-benzo[1,2-d:5,4-d']bis-[1,3]-oxazine-4,6-dione, in the unreacted state. The ultraviolet absorber has excellent stability to heat and oxidation, and is useful, for example, for protecting from ultraviolet light a molded article of a polymer whose deterioration by ultraviolet light is required to be retarded or prevented or for protecting from ultraviolet light an object subject to deleterious effects under ultraviolet light.
