CURABLE PHOTOCHROMIC COMPOSITIONS AND OPTICAL ARTICLES PREPARED THEREFROM. |
摘要 |
<p>The present invention provides a curable, organic polymeric photochromic composition comprising: a photochromic amount of at least one photochromic material; a polymeric polyol having carbonate groups along its backbone and having a number average molecular weight greater than 5000 g/mole; and a curing agent having reactive functional groups capable of reacting with hydroxyl groups on the polymeric polyol. After curing and after the Photochromic Performance Test the composition demonstrates a T1/2 fade rate of less than 200 seconds. Also provided is a photochromic article comprising a rigid substrate and a photochromic organic polymeric coating applied to a surface of the substrate. The photochromic organic polymeric coating comprises the composition described above.</p> |
