A resin composition including N-oxyls having a specific structure and a synthetic resin, such as a vinyl ester resin, an urethane(meth)acrylate resin, an unsaturated polyester resin, a polyester(meth)acrylate resin, and acrylic syrup. A producing process of a resin composition by preparing the synthetic resin through reaction in the presence of the N-oxyls. According to the above arrangement and producing process, it has become possible to provide a resin composition having excellent physical properties, such as storage stability and curing property, and capable of suppressing the coloring over time, and hence, can be used suitably in diversified fields, and to provide a producing process of such a resin composition capable of suppressing the coloring.
一种树脂组合物,包括具有特定结构的 N-氧基和合成树脂,如乙烯基酯树脂、聚氨酯(甲基)丙烯酸酯树脂、不饱和聚酯树脂、聚酯(甲基)丙烯酸酯树脂和丙烯酸糖浆。通过在 N-氧基存在下反应制备合成树脂的树脂组合物生产工艺。根据上述安排和生产工艺,可以提供一种具有优异物理性能(如储存稳定性和固化性能)的树脂组合物,该树脂组合物能够长期抑制着色,因此可适用于多种领域,还可以提供一种能够抑制着色的树脂组合物的生产工艺。
