Patent ID: 8545015

Claim:
A photochromic article comprising: a substrate; a primer layer comprising a first photochromic compound, said primer layer being positioned over said substrate, and said first photochromic compound having a first unactivated state absorbance of greater than 0 at all wavelengths from 340 nm to 380 nm, and a first unactivated state terminal minimum absorbance wavelength of greater than 380 nm; and a coating layer comprising a photochromic-dichroic compound, said coating layer being positioned over said primer layer, and said photochromic-dichroic compound having a second unactivated state absorbance of greater than 0 over at least a portion of wavelengths from 340 nm to 380 nm, and a second unactivated state terminal minimum absorbance wavelength of greater than 340 nm, wherein said second unactivated state terminal minimum absorbance wavelength is less than or equal to said first unactivated state terminal minimum absorbance wavelength.
