ABSTRACT:
A cathodochromic sodalite defined by the formula Na.sub.3 Al.sub.3 Si.sub.3 O.sub.12.NaX (X = Cl, Br or J) comprising at least one of the elements tin, lead and germanium in a quantity of between 0.05 and 2 atom % calculated with respect to silicon. The addition of the said elements results in an improvement of the reversible bleaching properties. Notably, a faster and also a more complete bleaching is obtained.
