Described are photochromic articles that include a substrate, a
temperature dependent reducing amount of at least one organic
photochromic material (b) that changes from more absorbing to less
absorbing of radiation in its activating spectral absorbance as the
temperature increases from 10.degree. C. to 35.degree. C. and at least
one other photochromic material (c) that is different from photochromic
material (b). In the article, photochromic material (b) is interposed
between photochromic material (c) and a source of activating radiation.
The photochromic article demonstrates a more consistent photochromic
response, for example, an optical density response loss of 50 percent or
less over a temperature range of from 10.degree. C. to 35.degree. C. as
measured in the Photochromic Temperature Dependence Test. Methods for
producing the aforedescribed articles are also disclosed.
