Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composition capable of forming a cured layer having excellent surface hardness, flexibility, heat-resistance and transparency, exhibiting low cure shrinkage in polymerization, and having low viscosity and good workability and provide an article having a cured layer of the composition. SOLUTION: The composition contains (A) an oligomer selected from urethane (meth)acrylate oligomer, epoxy (meth)acrylate oligomer and polyester (meth)acrylate oligomer and (B) a polycarbonate diol di(meth)acrylate obtained by reacting (b1) a polycarbonate diol having a number-average molecular weight of 250-850 with (b2) (meth)acrylic acid and/or a (meth)acrylic acid ester.
