摘要： An optical disc is constructed by joining a pair of resin substrates through an adhesive layer so that information carrying means is disposed inside. The resin substrate has a diameter-to-thickness ratio d/t.gtoreq.180. The adhesive layer has a Young's modulus of 0.1-1 kgf/mm.sup.2 at 20.degree. C. and a mechanical dissipation factor (tan.delta.) of 0.6-5.0 at 20.degree. C. The adhesive layer is formed of a hot melt adhesive, pressure-sensitive adhesive, room temperature curable adhesive or ultraviolet curable adhesive. The disc is resistant to both heat and vibration.

摘要： An optical recording medium is made by a step of bonding a light-transmissive substrate to a supporting substrate having a brightness of 8 or more and a saturation of 4 or less via a bonding layer composed of an epoxy resin; and a step of forming a transparent ink-receiving layer on a surface of the supporting substrate remote from the light-transmissive substrate. The bonding using the epoxy resin is conducted by a method of curing the resin by using a cationic initiator, a method of curing the resin by an addition reaction between the resin and a crosslinking agent containing an active hydrogen compound, a method of curing the resin by heating, or the like. In this invention, the bonding layer is composed of a material containing an epoxy resin instead of a radically polymerizable UV-curable resin typically used. Thus, although UV irradiation through the supporting substrate is not possible, the light-transmissive substrate can be securely bonded to the supporting substrate.

摘要翻译： 光记录介质是通过将透光性基板通过由环氧树脂构成的接合层，将亮度为8以上且饱和度为4以下的支撑基板接合的步骤制成的; 以及在远离所述透光性基板的所述支撑基板的表面上形成透明油墨接收层的工序。 使用环氧树脂的接合通过使用阳离子引发剂固化树脂的方法进行，通过树脂和含有活性氢化合物的交联剂之间的加成反应固化树脂的方法，固化树脂的方法 通过加热等。 在本发明中，接合层由含有环氧树脂的材料代替通常使用的可自由基聚合的UV固化树脂。 因此，虽然不能通过支撑基板进行紫外线照射，但是可以将透光性基板牢固地接合到支撑基板。
