Description of the Invention (1) Technical Field / The present invention relates to an optical disc substrate excellent in mold release and reverse warp deformation after molding. BACKGROUND With the progress of the information society, as an information recording medium, the market has shifted from the existing magnetic tapes and magnetic disks to highly integrated optical disks. In order to achieve universalization, it is necessary to reduce prices, so in recent years, efforts have been made to obtain cheaper materials and to investigate how to improve productivity. The term "optical disc" as used herein refers to recording in which digital signals such as sound and video are converted into pits on the surface of a plastic substrate. Laser readers are used, and LD (laser disk) is used. , VCD (Video Disc), Music CD (Compact Disc), CD-ROM (CD-ROM), CD-R (Recordable CD-ROM Drive), DVD — ROM (Read-Only Memory Multifunctional Digital Video Disc) ), DVD-RA Μ (Random Access Memory Multifunctional Digital Video Optical Disc Player), DVD-R (Recordable Multifunctional Digital Video Optical Disc Player), etc. As for the method of forming the cavity, there is a method of using a mechanical method of a stamper to use light to react an organic pigment pre-existing on the disk surface, but the method is not limited thereto. On the other hand, aromatic vinyl resins typified by polystyrene resins have been used in various fields because they are easy to mold. In the electronics field, due to its large demand, it can be responded by adding plasticizers or increasing the molecular weight of aromatic vinyl resins.

Description of the Invention (2) No. 5 9-1 4 0 2 0 7 is implemented by the addition of specific mineral oils, although some degree of fluidity improvement has been achieved However, it is not sufficient, and there are still problems in terms of moldability, and it also causes problems of reduction in mechanical strength and heat resistance of molded products. In addition, Japanese Patent Laid-Open No. 3-3 3 1 4 2 discloses a styrene-based resin composition having improved fluidity while maintaining mechanical strength and heat resistance. enough. However, since such a styrene-based resin composition requires high manufacturing technology and high cost, it is difficult to avoid the problem of increased cost. In addition, as a material for optical disc substrates, the use of styrene has been reviewed. However, there are only problems in which the impact strength is small and the molded product is easily broken during demolding in the molding process. In order to manufacture a molded article without warping, it is necessary to extend the cooling time, so that the molding cycle is too long, the productivity is poor, and the problem of poor transcription. Disclosure of the Invention As a result of various aspects of the review by the present inventors in order to solve the aforementioned problems, it was found that the optical disc substrate made of a specific styrene resin (X) can be improved in terms of strength, heat resistance and transcription, and finally completed this invention.

Description of the invention (40) As can be seen from Tables 3 and 4, Experiments No. 2 1 to 3 3 have strength, moldability, mold release, and transcription properties as optical disk substrates. Excellent characteristics, but experiments No. 0.3 to 40 are regarded as the fact that the characteristics of the optical disc substrate are inferior. Industrial Applicability The optical disc substrate using the present invention is excellent in strength, moldability, mold release property, and transcription property, can be easily produced at low manufacturing cost, and is extremely industrially useful.
