This invention relates to (meth)acrylates represented by formula (1):
wherein, R₁ and R₂ are each independently H or CH₃ and average value of n is 1 - 5; resin composite comprising (A) an urethane (meth)acrylate and/or epoxy (meth)acrylate, (B) a (meth)acrylate represented by formula (1) above, (C) an ethylenically unsaturated compound other than component (A) or (B), and (D) a photopolymerization initiator; and cured products of said resin composites. The cured products of said resin composites of this invention have high refractive index and are superior in mold release property, shape reproducibility, restorability, and scratch resistance and suited in particular for transmission type screens.
本发明涉及式(1)所代表的(甲基)丙烯酸酯:
其中,R₁ 和 R₂ 各自独立地为 H 或 CH₃,n 的平均值为 1 - 5;树脂复合材料,包括 (A) 聚氨酯(甲基)丙烯酸酯和/或环氧(甲基)丙烯酸酯,(B) 上述式 (1) 所代表的(甲基)丙烯酸酯,(C) 除组分 (A) 或 (B) 以外的乙烯基不饱和化合物,以及 (D) 光聚合引发剂;以及上述树脂复合材料的固化产物。本发明的上述树脂复合材料的固化产物具有高折射率,在脱模性、形状再现性、修复性和抗划伤性方面都很出色,尤其适用于透射型屏幕。
