| 20090135462 | CLEAR TO CIRCULAR POLARIZING PHOTOCHROMIC DEVICES AND METHODS OF MAKING THE SAME - The present invention provides optical elements comprising a photochromic linear polarizing element and a birefringent layer that circularly or elliptically polarizes transmitted radiation. The photochromic linear polarizing element comprises a substrate and either: (1) a coating comprising an aligned, thermally reversible photochromic-dichroic compound having an average absorption ratio of at least 1.5 in an activated state, and being operable for switching from a first absorption state to a second absorption state in response to actinic radiation, to revert back to the first absorption state in response to thermal energy, and to linearly polarize transmitted radiation in at least one of the two states; or (2) an at least partially ordered polymeric sheet connected to the substrate; and a thermally reversible photochromic-dichroic compound that is at least partially aligned with the polymeric sheet and has an average absorption ratio greater than 2.3 in the activated state. | 05-28-2009 |
| 20110080628 | CLEAR TO CIRCULAR POLARIZING PHOTOCHROMIC DEVICES - The present invention provides composite optical elements including a photochromic linear polarizing element and a birefringent layer such that composite optical element circularly or elliptically polarizes transmitted radiation. The photochromic linear polarizing element is formed from (i) an at least partially ordered polymeric sheet; and (ii) a reversible photochromic-dichroic material that is at least partially aligned with the polymeric sheet and has an average absorption ratio of at least 1.5 in the activated state. The birefringent layer includes a polymeric coating or a polymeric sheet connected to the photochromic linear polarizing element. | 04-07-2011 |

| 20100076143 | LOW TEMPERATURE APPLICATION COATING COMPOSITION COMPRISING POLYUREA AND A PHOSPHORUS-CONTAINING POLYOL AND FOOTWEAR COMPRISING POLYUREA - Coating compositions comprising a polyurea formed from a reaction mixture comprising: (a) a first component comprising an isocyanate, the first component having a viscosity of ≦2000 centipoise at a temperature ≧7° C.; and (b) a second component comprising an amine. Substrates coated at least in part with such a composition are also disclosed. Footwear coated at least in part with polyurea are also disclosed. | 03-25-2010 |
| 20100136345 | POLYUREA COATING COMPRISING A POLYAMINE/MONO(METH)ACRYLATE REACTION PRODUCT - Coating compositions comprising a polyurea formed from a reaction mixture comprising isocyanate and a (meth)acrylated amine are disclosed. The (meth)acrylated amine is the reaction product of a polyamine and a mono(meth)acrylate; the ratio of equivalents of isocyanate groups to equivalents of amine groups is greater than 1 and the isocyanate and the (meth)acrylated amine reaction product can be applied to a substrate at a volume mixing ratio of 1:1. Methods for using the coatings, and substrates coated therewith are also disclosed. | 06-03-2010 |
