THIN ALUMINIUM BODY PIGMENTS, METHOD OF PRODUCTION THEREOF AND APPLICATION OF THESE ALUMINIUM PIGMENTS Russian patent published in 2008 - IPC C09C1/64 C09C3/04 B22F1/02 C09D5/00 C09D5/38 A61Q3/02 B02C17/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in paint and varnish, cosmetic and other industries. Offered aluminium pigments are at least partially covered with greasing and having a) water spread coefficient within 40000 and 130000 cm²/g; b) average thickness h within less than 100 to 30 nm calculated from water spread coefficient and integral distribution h₅₀ by data processing on thickness of scanning electron microscopy; c) relative width Δh of thickness distributions determined by data processing on thickness of scanning electron microscopy and calculated by corresponding relative frequencies integral curve by formula: 70% to 140%; d) form-factors d₅₀/h more than 200; e) roughness degree calculated by specific surface area measured by BET method and spread coefficient according to the following formula: BET value/2 spread coefficient, from 0.30 to 0.9. Method of production of these pigments, as well as varnishes containing these pigments is offered.

EFFECT: production of very thin aluminium pigments without adhesive polymer film having excellent spreading capacity, high gloss value and improved metallic appearance, as well as reduced agglomeration tendency.
