چکیده انگلیسی
In the present study, colorimetric characteristics of six photochromic bis-azospiropyrans based dyes are investigated. The colorimetric axes of these dyes in terms of hue, chroma and lightness are considered via UV exposure time. Results showed that, the hue angle of these dyes changes rapidly at the first times of UV irradiation, and then remains almost constant. However, chroma and lightness continuously change till about 80-240Â s for different dyes. In addition, it is shown that variations of lightness and chroma by UV exposure time have an exponential trend, which can be modeled mathematically.
