<p><P>PROBLEM TO BE SOLVED: To provide an aqueous dispersion of an ethylene-based polymer composition, an organic solvent dispersion of an ethylene-based polymer composition and an additive for a printing ink that impart a performance having both excellent wear resistance and excellent blocking resistance to an aqueous ink and an oily ink. <P>SOLUTION: The aqueous dispersion of an ethylene-based polymer composition is produced by dispersing, in water, particles of an ethylene-based polymer composition comprising (A) an ethylene-based polymer having an Mn in a range of 400-8,000, an Mw/Mn of 3 or less and a relationship between a crystallization temperature and a density which satisfies a specified formula and (B) a modified ethylene-based polymer being modified with an unsaturated carboxylic acid or its derivative or with a sulfonate wherein the content of the unsaturated carboxylic acid or its derivative is a concentration of 30-100 mgKOH as determined by a KOH titration method per gram of the modified polymer or the content of the sulfonate is 0.1-50 millimole equivalents in terms of -SO<SB>3</SB>- per gram of the modified polymer. <P>COPYRIGHT: (C)2003,JPO</p> |
