Color-neutral uv blocking coating for plastic lens |
| abstract |
Polymeric coatings containing both UV absorbers and dyes are employed to produce transparent, durable film coatings that can significantly increase the level of UV radiation blockage when coated onto substrates including ophthalmic lenses. The dye comprises 1-[(4-methylphenyl)amino]-4-hydroxy-9,10-anthracenedione. The color-neutral film coatings are resistant to weather and UV degradation. |
