  • 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.

  • Publication number: 20220171110
    Abstract: An optical article that includes an optical element and an anisotropic coating layer formed over at least a portion of the optical element. The anisotropic coating layer can include a first light-influencing zone comprising at least one first anisotropic material and a second light-influencing zone comprising at least one second anisotropic material. The at least one of the first light-influencing zone and the second light-influencing zone further include at least one dichroic material and/or at least one photochromic-dichroic material such that the first light-influencing zone and the second light-influencing zone exhibit a different color property, a different photochromic-dichroic reversible change, a different amount of polarization, or a combination thereof.

  • Patent number: 11036065
    Abstract: A method of making an optical article having multiple light-influencing zones can include: forming an alignment coating layer having a first alignment region and a second alignment region over at least a portion of an optical element; applying at least one anisotropic material over the first alignment region and the second alignment region by an inkjet printing device; and applying at least one dichroic material and/or at least one photochromic-dichroic material over at least one of the first alignment region and the second alignment region to form a first light-influencing zone over the first alignment region and a second light-influencing zone over the second alignment region.

  • Patent number: 10888824
    Abstract: The present invention is directed to a method for treating a surface of a filled microporous membrane. The microporous membrane includes a polyolefinic matrix, inorganic filler distributed throughout the matrix, and a network of interconnecting pores throughout the membrane. The method includes sequentially (1) contacting at least one surface of the membrane with a treatment composition of a silane-functional polyamine compound having at least one alkoxy silane group, such that the silane-functional polyamine compound is in intimate contact with the filler present in the matrix; and (2) subjecting the membrane of (1) to conditions sufficient to effect a condensation reaction between the inorganic filler and the silane-functional polyamine compound. Treated membranes also are provided.

  • Patent number: 10882928
    Abstract: The present invention includes a process for producing treated filler that includes (a) treating a slurry that includes untreated filler, where the untreated filler has not been previously dried, with a treating composition that includes a treating agent, thereby forming a treated filler slurry, and (b) drying the treated filler slurry to produce treated filler. The treating agent can include a polymer having (i) at least one first group that interacts with the untreated filler and (ii) at least one second group that interacts with a rubber matrix into which the treated filler is incorporated. The present invention also is directed to treated filler prepared by the process, as well as rubber compounding compositions and tires including the treated filler.
