    • A UV-cure adhesive for bonding an optical disk substrates one or both of which having a semitransparent reflective film of silver, a silver alloy, or the like. The thus produced bonded optical disk has a high durability equivalent to those of optical disks using a conventional gold semitransparent reflective film and is free of voids (air bubbles) that might be produced while the optical disk is manufactured by an optical disk manufacturing apparatus. The degradation in reflectance of the semitransparent reflective film can be suppressed even when the produced optical disk is exposed to direct sunlight for a long time. A UV-cure adhesive resin composition for bonding optical disk substrates contains (A) an epoxy (meth)acrylate, 2,2-dimethoxy-1,2-diphenylethan-1-one and (E) a monofunctional, bifunctional, trifunctional (meth)acrylate monomer, and has an electrical resistivity of 1000 MΩ·cm or less at 25° C.
    • 一种UV固化粘合剂,用于粘结其中一个或两个具有银半透明反射膜,银合金等的光盘基片。 如此制造的粘合光盘具有与使用传统的金半透明反射膜的光盘相当的耐久性,并且在由光盘制造装置制造光盘时可以产生空隙(气泡)。 即使所制造的光盘长时间暴露在阳光直射下,也可以抑制半透射反射膜的反射率的劣化。 用于粘合光盘基片的UV固化粘合树脂组合物包含(A)环氧(甲基)丙烯酸酯,2,2-二甲氧基-1,2-二苯基乙烷-1-酮和(E)单官能,双官能,三官能(甲基) )丙烯酸酯单体,在25℃下的电阻率为1000Moga.cm以下

    • Disclosed is an adhesive which enables to obtain a bonded optical disk, wherein optical disks having a total reflection film or a translucent reflection film made of silver or a silver alloy are bonded together, which exhibits high adhesion strength between the reflection film and a cured product of the adhesive as well as between a polycarbonate substrate and the cured product of the adhesive, while having high durability equivalent to those of the conventional optical disks using translucent reflective film made of gold. Specifically disclosed is an ultraviolet-curable adhesive resin composition containing a bisphenol-type epoxy (meth)acrylate (A), a di(meth)acrylate (B) and a photopolymerization initiator (C) which is characterized in that the di(meth)acrylate (B) is composed of one or more selected from a di(meth)acrylate (B-1) having an adipate structure, a di(meth)acrylate (B-2) having a caprolactone-modified structure, an alkylene oxide-modified neopentyl glycol di(meth)acrylate compound (B-3) and an alkylene oxide-modified 1,6-hexanediol di(meth)acrylate compound (B-4).
    • 公开了一种能够获得粘合光盘的粘合剂,其中具有全反射膜或由银或银合金制成的半透明反射膜的光盘结合在一起,其在反射膜和固化产物之间显示出高的粘合强度 的粘合剂以及聚碳酸酯基材和粘合剂的固化产物之间,同时具有与使用由金制成的半透明反射膜的常规光盘相当的高耐用性。 具体公开了含有双酚型环氧(甲基)丙烯酸酯(A),二(甲基)丙烯酸酯(B)和光聚合引发剂(C))的紫外线固化性粘合性树脂组合物,其特征在于,所述二(甲基) 丙烯酸酯(B)由选自具有己二酸酯结构的二(甲基)丙烯酸酯(B-1),具有己内酯改性结构的二(甲基)丙烯酸酯(B-2),烯化氧 - 改性新戊二醇二(甲基)丙烯酸酯化合物(B-3)和烯化氧改性的1,6-己二醇二(甲基)丙烯酸酯化合物(B-4)。
