Description

574339 A7 __B7 V. Description of the invention (1) Field of invention (please read the notes on the back before filling out this page) The present invention relates to a photocurable composition. In addition, the present invention relates to the composition as a glue for optical discs. The use of adhesive. Background The recent development of information technology represented by computer technology, computer software technology, and communication technology printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs has enabled more data to be transmitted at high speeds. A recording medium capable of recording more data at a high density is needed and developed. As for such a high-density recording medium, a DVD (digital video disk or digital versatile disk) has been developed for the next generation Type recording media. DVDs are usually made by joining two magnetic disks, so an adhesive is needed to adhere the two magnetic disks. Examples of conventional adhesives include hot-melt adhesives, heat-curable adhesives Adhesives, anaerobic curable adhesives. However, these conventional adhesives have various disadvantages. For example, hot-melt adhesives have poor thermal stability and weather resistance. Therefore, it softens at high temperature, causing the magnetic disk to separate or deform due to reduced adhesiveness. Moreover, it is difficult to apply a hot-melt adhesive to a double-layer DVD having a translucent film as a recording film because of the hot-melt The adhesive has poor transparency. The problem with heat-curable adhesives is that the substrate forming the magnetic disk is deformed by heat during curing. Or, if a lower temperature is used, it takes a long time to cure the adhesive. . Anaerobic curable adhesives have poor productivity because curing the adhesive requires a longer cycle time. Light-curable adhesives have been proposed to solve these problems. For example, Japanese Patent Laid-Open Application No. 1 4 2 5 4 5/1 9 86 and number 8946 2/1 9 94 Reveal ultraviolet light UV — -4-This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) 574339 A7 _ B7 V.

Preferably, each component is added so as to form a cured product. The glass transition temperature is in the range of -30 to 200 ° C, preferably from 0 to 120 ° C. If the glass transition temperature is too low, the cured product may be in summer or at high temperatures Softening in a closed sunlight room may cause the substrate to be displaced or moved due to reduced adhesiveness. If the glass transition temperature is too high, the adhesiveness may be insufficient or the substrate may break when dropped or bent.

Description of the invention (23) (Please read the precautions on the back before filling this page) The "glass" used in the present invention “State temperature” means the maximum value of the loss tangent (tan5) when measured using a dynamic viscoelasticity measuring device at a frequency of 10 oscillations. The composition of the present invention is preferably irradiated with ultraviolet light, visible light, electron beam, or Others are cured. For example, when the compound of the present invention is applied between substrates so that the thickness of the adhesive layer is 10 to 100 micrometers, a metal halide lamp with a dose of 50 to 2000 millijoules / cm2 is used to irradiate the compound. Compounds, which can be easily cured. The photosensitive cured product of the compound of the present invention preferably has superior transparency. For example, a 60 micron thick layer of a cured composition has a light transmittance of 90 percent or more at 600 to 700 nanometers. If the light transmittance is less than 90%, the appearance of the disc may be damaged. Moreover, the light used to read the data stored in the magnetic disk is reduced due to the adhesive layer of the cured product, which hinders the reading operation. Therefore, it is better to prepare the composition of the present invention by combining the components so that the light transmittance of the cured product is within the aforementioned range. , So that the photosensitive cured product of the composition of the present invention has a refractive index of 1 · 5 1-1 · 70 at 25 ° C. If the refractive index of the photosensitive cured product exceeds this range, problems may occur when reading the data in the storage disk. The compounds of the present invention have good adhesion to a wide variety of materials, including plastics such as polycarbonate (PC) and polymethyl methacrylate (PMMA), metals (such as gold, silver, and brocade), and inorganic compounds (E.g. glass). Therefore, the composition is suitable for use as an optical disc. -26- This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 574339 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 24) Adhesive.
