PURPOSE:To provide a surface modifier for an organic pigment containing a specified N-(long chain acyl) basic amino acid, which shows good dispersion in order solvent, resin and rubber and produces an organic pigment having bright color tone and excellent water repellency and printing properties. CONSTITUTION:The modifier contains at least one N-(long chain acyl) basic amino acid having at least one 8-22C aliphatic acyl group in the molecule (e.g. N-lauroyllysine). Organic pigment treated with the modifier shows good dispersibility in an organic solvent such as methyl ethyl ketone or toluene, resins such as polyurethane or epoxy resins and rubber such as natural or styrene/butadiene rubbers, develops bright color, has excellent water repellency and printing properties and is suitable for coating, plastics, printing ink, rubber, stationery, paper-making, etc.
