Abstract: (A) Prepn. of blue-shade gloss pigments is obtd. by treatment of silicatic flakes which are coated with titanium dioxide (the titanium dioxide coating having a geometric layer thickness of 10-60 nm) with a reducing gas mixt. (which contains a vaporised organic cpd. and ammonia) at 800-900 degrees C. (B) Blue-shade gloss pigment is based on silicatic flakes which comprise a reduced titanium dioxide and has a geometric layer thickness of 10-60 nm and a CIELAB colour value -2 ≤ a* ≤ b* ≤ -20 (measurement angle 20 degrees ,'standard light type'D65).
