  A cured product that is reduced in warping and has high hardness can be obtained from an active energy ray-curable resin composition which uses a methacrylic acid ester polymer that has an acid value of 50 mg KOH/g or less and a transition metal content of 1 ppm or less, while containing 80% by mole or more of a polymer that has a double bond-terminated structure represented by formula (1). (In formula (1), R represents an alkyl group, a cycloalkyl group or an aryl group.)

  使用甲基丙烯酸酯聚合物的活性能量射线固化树脂组合物，其酸值不小于 50 毫克 KOH/克，过渡金属含量不小于 1 ppm，同时含有 80%（以摩尔计）或更多的具有式（1）表示的双键末端结构的聚合物，可以获得翘曲减少且硬度高的固化产品。(在式 (1) 中，R 代表烷基、环烷基或芳基）。

  It is an object of the present invention to provide a moisture-curable polyurethane hot-melt resin composition having excellent waterproof properties, drop impact resistance, and flexibility. The present invention provides a moisture-curable polyurethane hot-melt resin composition containing a urethane prepolymer having an isocyanate group, the urethane prepolymer being produced through a reaction of a polyol (A) with a polyisocyanate (B), wherein the polyol (A) contains a polyether polyol (A-1), a crystalline polyester polyol (A-2), an amorphous polyester polyol (A-3), and an acrylic polyol (A-4). The present invention also provides an adhesive containing such a composition and an article in which such a composition is used.
