The present invention relates to naphthopyran compounds that include at least one compound represented by the following Formulas (I), (II), and (III): With reference to Formulas (I), (II), and (III), there is the proviso that: (i) at least one R1 is a group L; and/or (ii) B and/or B' is substituted with at least one group L. The group L can be described as a lengthening group. The present invention also relates to photochromic-dichroic naphthopyran compounds and photochromic-dichroic articles containing such compounds.
The present invention relates to a method of preparing a photochromic-dichroic film that includes a photochromic-dichroic layer. The method includes forming a molten thermoplastic photochromic-dichroic composition that includes a thermoplastic polymer and a photochromic-dichroic compound. Optionally at least one further molten thermoplastic composition is formed, each of which independently includes a further thermoplastic polymer. A molten stream is formed that includes a first molten layer (29) composed of the molten thermoplastic photochromic-dichroic composition, and at least one further molten layer (26, 32), each of which is independently composed of a further molten thermoplastic composition. The molten stream is passed between a rotating roll (11) and a continuous belt (14) that move in the same relative direction. A photochromic-dichroic film having reduced/minimal optical distortion is obtained (e.g., continuously) from between the rotating roll and the continuous belt.
The present invention relates to a method of preparing a photochromic-dichroic film. The method includes forming a molten extrudate that includes a first molten thermoplastic layer that includes one or more photochromic-dichroic compounds, that is interposed between separate second and third outer molten thermoplastic layers. The molten extrudate is cooled so as to form a multilayer film that includes a first layer that includes one or more photochromic-dichroic compounds, that is interposed between separate second and third outer layers. The second and third outer layers are removed from the first layer of the multilayer film. The resulting sole first layer, which is retained, defines the photochromic-dichroic layer, which exhibits reduced or minimal optical distortion.
The present invention relates to photochromic articles that include a substrate and at least one photochromic material that is adapted to change from an unactivated form to an activated form by exposure to radiation substantially in the wavelength range from 380 to 450 nanometers when measured over a range of from 380 to 700 nanometers. The photochromic article is also adapted to retain at least 12 percent of the delta OD measured in the Outdoor Test when tested in the Behind the Windshield Test. The photochrome material can be selected from certain compounds including, for example, fluoranthenoxazines, naphthopyrans, phenanthropyrans, fluoranthenopyrans, and indenonaphthopyrans, which each have bonded thereto at least one chiral or achiral lengthening group that provides the photochromic compound with dichroic properties. The present invention also relates to methods of forming a photochromic article.
