Embodiment 1

[0057] Based on the weight part of resin 1, 20 parts by weight of resin 1 having the aforementioned structure, 20 parts by weight of isobornyl acrylate, 15 parts by weight of tetrahydrofurfuryl acrylate, 2 parts by weight of Irgacure184, 2 parts by weight of Put Irgacure 651, 1 part by weight of TEGO Flow 300, 2 parts by weight of vinyl tris (β-methoxyethoxy) silane and 0.2 parts of NANOBYK 3601 into a container with a stirrer, stir and mix evenly, use The cured resin composition was prepared by filtering through a filter cloth with a pore size of 0.1 μm. The cured resin composition obtained above was spin-coated on a polycarbonate substrate sputtered with a metal reflective layer by using a coater to form a coating with a thickness of about 100 μm. Curing by UV radiation (energy is 600mJ / cm 2 ) and perform performance evaluation.

Embodiment 2

[0059] Based on the parts by weight of resin 2, 40 parts by weight of resin 2 having the aforementioned structure, 15 parts by weight of 2-phenoxyethyl acrylate, and 5 parts by weight of ethoxylated trimethylolpropane triacrylate , 5 parts by weight of trimethylolpropane triacrylate, 2 parts by weight of Darocur 1173, 3 parts by weight of Irgacure 651, 0.2 parts by weight of TEGO Glide 450 and 1 part by weight of vinyltrimethoxysilane coupling agent Put it into a container with a stirrer, stir and mix evenly, and filter through a filter cloth with a pore size of 0.1 μm to prepare a cured resin composition. The cured resin composition obtained above was spin-coated on a polycarbonate substrate sputtered with a metal reflective layer by using a coater to form a coating with a thickness of about 100 μm. Curing by UV radiation (energy is 300mJ / cm 2 ) and perform performance evaluation.

Embodiment 3

[0061] Based on the parts by weight of resin 3, 50 parts by weight of resin 3 having the aforementioned structure, 30 parts by weight of 2-phenoxyethyl acrylate, 15 parts by weight of tetrahydrofurfuryl acrylate, and 8 parts by weight of three Methylolpropane triacrylate, 6 parts by weight of Irgacure 184, 2 parts by weight of Irgacure 651, 0.2 parts by weight of TEGO Glide 450 and 5 parts by weight of vinyltrimethoxysilane coupling agent are put into a container with agitator , stir and mix evenly, and filter through a filter cloth with a pore size of 0.1 μm to prepare a cured resin composition. The cured resin composition obtained above was spin-coated on a polycarbonate substrate sputtered with a metal reflective layer by using a coater to form a coating with a thickness of about 100 μm. Curing by UV radiation (energy 100mJ / cm 2 ) and perform performance evaluation.

Abstract

The invention relates to an ultraviolet light or electron beam-cured resin composition for a blue-ray disc. The cured resin composition can be obtained by the following steps of: based on the parts by weight of a prepolymer, mixing 20-80 parts by weight of urethane acrylate resin prepolymer, 10-50 parts by weight of active monofunctional monomer, 0-10 parts by weight of bifunctional monomer or multifunctional monomer (preferably 1-10 parts by weight of bifunctional monomer or multifunctional monomer), 0-8 parts by weight of photo initiator and 0.2-5 parts by weight of aid; stirring uniformly;and filtering. Blue laser light with the wavelength of about 405 nanometers can pass through an euphotic layer obtained by curing the cured resin composition, so that information recording can be carried out on the blue-ray disc and the blue-ray disc can be recycled.

Description

technical field [0001] The invention relates to an ultraviolet light or electron beam curable resin composition for Blu-ray discs. The light-transmitting layer obtained after curing the cured resin composition can pass blue laser light with a wavelength of about 405 nm, so that information can be recorded on Blu-ray discs and Blu-ray discs are recyclable. Background technique [0002] In recent years, with the development of information technology, it is necessary to realize the transmission of large-capacity information records. At the same time, high-density and large-capacity optical discs capable of recording and reproducing large-capacity images, music, data, and the like are required. [0003] Traditional DVD requires a laser head to emit red laser light (wavelength 650nm) to read or write data. Generally, lasers with shorter wavelengths can record or read more information per unit area. Therefore, Blu-ray greatly improves the storage capacity of optical discs. For o...
