Surface modifier for inorganic and organic pigment

Abstract

Abstract PURPOSE:The titled surface modifier useful in the field of coating compound, resin, ink, rubber, stationary, cosmetic, etc., containing a specific acidic amino acid-omega-long-chain amide. CONSTITUTION:The aimed surface improver containing at least one acidic amino acid-omega-long-chain amide (e.g. glutamic acid-gamma-palmitylamide, etc.) containing 6-22C aliphatic alkyl group. The amide is readily obtained by introducing a hydrophobic amide group (e.g. hexylamine, lauryamine, etc.) to an alpha,epsilon-acidic amino acid such as glutamic acid, aspartic acid, etc. The modifier is added to inorganic or organic pigment to be modified and ground together by the use of a grinder such as ball mill, atomizer, etc., to carry out surface modification.
