Definitions
- the present invention relates to photocurable resin compositions having a low chlorine content.
- the present invention relates to a photocurable resin compositions suitable for use with information disks, including in particular, disks having multiple elements comprising information (or the ability to receive and retain information) , preferably, this will include optical disks ⁇ i . e . , those wherein the information, preferably digital information, is recorded and/or retrieved using optics) for example, digital video disks or digital versatile disks, commonly referred to as a DVD's.
- Recent progress of information technologies including computer devices, computer software, and communication technologies has allowed a high speed conveyance of mass information.
- recording media which can record much more information at high density have been desired and the development of such recording media is ongoing.
- An example of such high-density recording media is a DVD which has been developed as a recording media for wide use in the next generation.
- the DVD differs from conventional CDs (compact disks) in that the DVD is manufactured by adhering two sheets of disks. Therefore, an adhesive for adhering the two sheets of disks is required and use of hot -melt, heat -curable, anaerobic curable, or similar adhesives has been attempted.
- hot-melt adhesives have insufficient heat stability and weatherability. Because these adhesives soften at a high temperature, the decreased adhesive strength causes the adhered disks to be separated and deformed. In addition, since transparency of the adhesive is insufficient, it is difficult to use these adhesives for the DVD comprising two recording films of which one is translucent .
- a problem with heat-curable adhesives is that heat during curing causes the substrate for forming a disk to deform and the curing time is long. On the other hand, anaerobic curable adhesives require a certain period of time for curing, thereby resulting in reduced productivity.
- UV curable adhesives comprising a urethane acrylate as a major component have been disclosed in Japanese Patent Applications Laid-open No. 142545/1986 and No.
- optical disks manufactured using these conventional photocurable adhesives exhibit only insufficient moisture resistance and heat resistance. Information recorded in such disks may be lost over time under high temperature and high humidity conditions .
- the present invention provides a photocurable resin composition useful as an adhesive for fabricating information disks exhibiting superior heat resistance and moisture resistance.
- the present inventors have undertaken extensive studies and found that a photocurable resin composition with a reduced chlorine content, when used as an adhesive for information disks, induces almost no deterioration of metallic films on substrate surfaces for optical disks and can produce information recording disks with excellent moisture resistance and heat resistance.
- an object of the present invention is to provide a photocurable resin composition
