<p>The object is to provide: a polyurethane composition which is non-adherent and therefore cannot be adhered on a molding apparatus or the like, which has excellent melt-molding properties, which has excellent adhesion to a silicone, and which is useful for a molded article, a composite molded article or an ink binder; and a molded article, a composite molded article, an ink binder and an ink composition each of which comprises the polyurethane composition. Thus, disclosed are: a polyurethane composition comprising: a polyurethane (A) containing a constituent unit (I) represented by the general formula (I) at a ratio of 0.1 to 20% in its molecule; and a metal compound (B) selected from an organic Zn compound, an organic Bi compound, an organic Ti compound and an organic Zr compound in an amount of 0.1 to 2000 ppm; a molded article comprising the polyurethane composition; a composite molded article having a layer composed of the polyurethane composition and a silicone layer; and an ink binder and an ink composition each of which comprises the polyurethane composition. (I) wherein R1 and R2 independently represent a hydrogen atom or a C1-6 alkyl group.</p> |
