  • Curable photochromic compositions
    Patent number: 11795331
    Abstract: A curable photochromic composition can include: (a) a first component having a first compound with at least two active hydrogen-functional groups and an active hydrogen-functional group equivalent weight of at least 1000; (b) a second component having at least one of a polyisocyanate and a blocked polyisocyanate; and (c) at least one photochromic compound. The ratio of total isocyanate and blocked isocyanate group equivalents of the second component to total active hydrogen-functional group equivalents is at least 4:1.
    Type: Grant
    Filed: February 17, 2021
    Date of Patent: October 24, 2023
    Assignee: Transitions Optical, Inc.

  • Compounds for coordinating with a metal, compositions containing such compounds, and methods of catalyzing reactions
    Patent number: 11618756
    Abstract: A compound capable of coordinating with a metal includes a chemical structure as shown in claim 1, in which: EPD represents a group having an electron pair donor atom; B and B? are each independently an aryl group, a heteroaryl group, an alkenyl group, or alkynyl group, or B and B? form a spirocyclic group; and R1, R2, and R3 are selected from various substituents.
