    摘要: The organic photochromic composition of this invention comprises spiro [indoline-2,3'-[3H]-naphth [2,1-b] [1,4] oxazine] (SO) dye and an unconventional ultraviolet stabilizer. The ultraviolet stabilizer improves the light fatigue resistance of the SO dye and will not hinder the photocolorability of the photochromic composition.

    摘要: Laser protection is provided by utilizing certain organic polymers with carboxylic or sulfonic acid groups which exchange their protons with cupric or ferrous metal ions to form cupric or ferrous ion-containing polymers. In addition, laser protection is also provided utilizing organic polymers with functional groups which are capable of forming complexes with cupric or ferrous metal ions. The optical absorption of the metal ions (e.g., the transition metal and rare earth ions) in these two types of metal ion-containing polymers are similar to those in absorbing glasses and will provide absorption in the near IR portion of the spectrum (i.e., greater than 680 nm). Thus, metal ion-containing polymers can be as useful for laser eye protection as known absorbing glasses, while providing high visual transmittance and light weight.

    摘要: Light fatigue resistant, non-orange, photochromic mercury complexes of asymmetrical diarylthiocarbazones for use in making photochromic sunglass lenses, ski goggles, and the like. The compounds comprise the class of mono and bis mercury diarylthiocarbazonates wherein one aryl group is an aryl group substituted at the ortho position with an electron withdrawing group such as CF.sub.3 and the other aryl group is different from the first and can comprise variously substituted or unsubstituted phenyl or naphthyl groups.

    摘要: An organic photochromic composition comprising spiro [indoline-2,3'-[3H]-naphth [2,1-b] [1,4] oxazine] dye (spirooxazine dye) and unconventional ultraviolet stabilizers. The ultraviolet stabilizers improve the light fatigue resistance of the spirooxazine (S.O.) dye and will not hinder the photocolorability of the photochromic composition. The unconventional ultraviolet stabilizers belong to the class of hindered amine light stabilizers (HALS) and excited state quenchers.

    摘要: The organic photochromic composition of this invention comprises trifluoromethyl substituted spiro (indoline-2,3'-(3H) napth-(2,1-b)(1,4)oxazine) (SO) dyes. This new class of (SO) photochromic compounds has a more neutral color when subjected to ultraviolet light irradiation.When used with a photochromic plastic embodiment, these (SO) compounds give the plastic embodiment a high luminous transmittance in an unactivated state, which can be darkened significantly when subjected to ultraviolet light irradiation. When an ultraviolet stabilizer is used with the photochromic compositions of this invention, the light fatigue resistance of the (SO) dye is improved and it will not hinder the photocolorability of the photochromic composition.
