Estimating the term…
A method for obtaining the chromatic variation of objects, in response to external stimuli, and a product obtained thereby. The method comprises the incorporation in the desired objects of various pigments having combined effects comprising a luminescent pigment, a thermochromic pigment permitting the change in the color according to the temperature and/or a hygroscopic pigment which will provoke a variation in the chromatic characteristics according to humidity. The objects manufactured make it possible to obtain effects of luminescence and of chromatic variation as the temperature and humidity vary.
Objects having chromatic variation, in response to external stimuli, both with daytime vision and night vision, the incorporation in said objects of at least one of a luminescent pigment, a thermochromic pigment to allow variation in color according to temperature and a hygroscopic pigment that varies in chromatic characteristics according to humidity, said pigments being in conjoint form in their mass.
