- HIGH-GLOSS MULTILAYER EFFECT PIGMENTS HAVING A NON-SILVER INTERFERENCE COLOR AND A NARROW SIZE DISTRIBUTION AND METHOD FOR THE PRODUCTION THEREOF

摘要

It relates to a multilayer pearl luster pigment comprising a shape of a transparent base, - the present invention has an optically active coating provided play portlets The optically active coating is at least (A) the refractive index n non-absorbent and having a ≥ 1.8 - index layer A, (B) the refractive index n 1.8 having a low-index layer B, (C) the refractive index n non-absorbent and having a ≥ 1.8 - index layer C, and (D) at least one outer protective layer D optionally And including, The multilayer pearl luster pigments, the index D _10, D _50, D ₉₀ and 0.7 - 1.4, by volume having a span ΔD of the range have a cumulative frequency distribution of average size distribution functions, the span ΔD is the formula (Ⅰ) _{ΔD = (D 90 - D 10} ) / D 50 (Ⅰ) It is calculated according to the. The invention relates to a method for producing a further such multilayer pearl luster pigment, and its uses.
