A photocurable resin composition comprises a cationic polymerizable compound (A), an acrylic resin (B) and a cationic photopolymerization initiator (C), in which the acrylic resin (B) has a cationic polymerizable functional group, and the content of the component (A) is 30 to 95 parts by mass and the content of the component (B) is 5 to 70 parts by mass, based on 100 parts by mass of the total amount of the components (A) and (B). In addition, the functional group of the acrylic resin (B) preferably contains at least one of a cyclic ether group, a vinyloxy group, an acid adduct of a vinyloxy group, and an active hydrogen group, with the active hydrogen group being a hydroxyl group is more preferable.
The photocurable resin composition which has sufficient curability and sufficient adhesiveness to rigid plastics such as polycarbonate and PET having poor adhesive property.
一种光固化树脂组合物包括阳离子可聚合化合物 (A)、丙烯酸树脂 (B) 和阳离子光聚合引发剂 (C),其中丙烯酸树脂 (B) 具有阳离子可聚合官能团,以组分 (A) 和 (B) 总量的 100 重量份为基准,组分 (A) 的含量为 30 至 95 重量份,组分 (B) 的含量为 5 至 70 重量份。此外,丙烯酸树脂(B)的官能团最好含有环醚基、乙烯氧基、乙烯氧基的酸加合物和活性氢基中的至少一种,活性氢基最好是羟基。
这种光固化树脂组合物对聚碳酸酯和 PET 等粘合性较差的硬质塑料具有足够的固化性和足够的粘合性。
