Abstract
Iron effect pigments having a thickness distribution, determined via thickness counting by scanning electron microscopy (SEM), as a cumulative undersize distribution with: a) an h50 value from 10 to 55 nm; and b) an h90 value from 20 to 80 nm, and also a method for producing the pigments, and the use of the iron effect pigments. The disclosure further relates to a printing ink comprising the iron effect pigments of the invention.
Claims20
Iron effect pigments wherein the iron effect pigments have a thickness distribution as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative undersize distribution, with
- a) an h50 having a range from 10 to 55 nm;
- and
- b) an h90 having a range from 20 to 80 nm, wherein the iron effect pigments are platelet-shaped iron pigments having a platelet-shaped iron core.
Iron effect pigments wherein the iron effect pigments have a thickness distribution as determined via thickness counting by scanning electron microscopy (SEM) and represented as cumulative undersize distribution, with
- a) an h50 having a range from 10 to 55 nm;
- and
- b) an h90 having a range from 20 to 80 nm;
