Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 37 words
Flaky coloured pigments comprising a flaky substrate the surface of which is covered by a finely divided colour pigment adhering uniformly to the flaky substrate by the use of an organic high molecular compound as a binder.
Claim 2
Dependent Claim 37 words
Flaky coloured pigments comprising a flaky substrate the surface of which is covered by a finely divided colour pigment adhering uniformly to the flaky substrate by the use of an organic high molecular compound as a binder.
Claim 3
Dependent Claim 38 words
A flaky pigment according to claim 1 characterized in that the flaky pigment contains about 0.5 to about 30 % by weight of the colour pigment and about 0.1 to about 10 % by weight of the binder.
Claim 4
Dependent Claim 60 words
Process for the production of flaky coloured pigments characterized in that a flaky substrate is suspended in a dispersion or a solution of a finely divided colour pigment, the resulting suspension is mixed with a solution of an organic high molecular compound and the colour pigment and the organic high molecular compound are caused to precipitate onto the flaky substrate.
Claim 5
Dependent Claim 60 words
Process for the production of flaky coloured pigments characterized in that a flaky substrate is suspended in a dispersion or a solution of a finely divided colour pigment, the resulting suspension is mixed with a solution of an organic high molecular compound and the colour pigment and the organic high molecular compound are caused to precipitate onto the flaky substrate.
Claim 6
Dependent Claim 12 words
Use of the flaky coloured pigments according to claim 1 in cosmetics.
