An ink jet composition of the invention is discharged by an ink jet method and includes: metal powder; an organic solvent; and a resin having a styrene-maleic acid structure as a binder resin, in which the ink jet composition contains metal powder surface-treated with a fluorine-based compound as the metal powder.

A resin coated inorganic or metallic pigment includes inorganic or metallic particles (A) and an acrylic copolymer (B) formed on the inorganic or metallic particles (A) by subjecting a radically polymerizable unsaturated carboxylic acid or radically polymerizable phosphate monomer (B1) and a monomer (B2) containing 3 to 6 (meth)acryloyloxy groups per molecule to radical polymerization reaction using a polymerization initiator (C) containing a nitrile group, wherein the inorganic or metallic particles (A) are coated with a coating resin including the acrylic copolymer (B), and the acrylic copolymer (B) has at a tail thereof a structure which is derived from the polymerization initiator (C) and which is represented by the following general formula (1):

##STR00001##

wherein R.sup.1 represents a methyl group, and R.sup.2 represents an alkyl group having 2 to 5 carbon atoms, or the like.

The invention relates to a surface-modified effect pigment comprising particular additives and to the production thereof. The present invention further provides a nail varnish composition comprising a) at least one effect pigiment that has been surface-modified with a starting material (additive), where the effect pigment comprises a substrate in platelet form and optionally at least one coating applied to the substrate, b) at least one hydrocarbon resin as binder, and c) at least one solvent or solvent mixture, where the starting material (additive) for surface modification of the effect pigment is at least one compound taken from the group consisting of phosphoric ester-containing, phosphonic ester-containing, phosphonic acid-containing, fatty acid-containing and/or silane-containing compounds or mixtures thereof.
