Embodiment

[0183] Although examples are given below to describe the present invention in more detail, the present invention is not limited by these examples.

Synthetic example 1

[0185] (M-1: Dimethacrylate of NPG-2EO)

[0186] In a flask equipped with a stirring device, a thermometer, a condenser, and a mixed gas introduction tube of air and nitrogen, 192g of neopentyl glycol 2-molar adduct of ethylene oxide (hereinafter referred to as "NPG-2EO"), 400g Methyl acrylate (hereinafter referred to as "MMA"), 3.84g of dibutyltin oxide (hereinafter referred to as "DBTO"), and 19.2mg of 4-hydroxy-2,2,6,6-tetramethylpiperidine-N- Oxy group (hereinafter referred to as "4H-TEMPO"), stirred, and heated to 110°C. Only the methanol generated by the reaction was distilled off, and the transesterification reaction was performed for 6 hours. MMA was distilled off from the obtained reaction liquid to obtain dimethacrylate of a 2-molar adduct of neopentyl glycol with ethylene oxide. This is referred to as compound (M-1).

[0187] When the content of sulfur atoms contained in the obtained compound (M-1) was measured by inductively coupled plasma analysis (Inductively Coupl...

Synthetic example 2

[0189] (M-2: Dimethacrylate of NPG-4EO)

[0190] In a flask equipped with a stirring device, a thermometer, a condenser, and a mixed gas introduction tube of air and nitrogen, 280 g of neopentyl glycol 4 mol adduct of ethylene oxide (hereinafter referred to as "NPG-4EO"), 400 g of MMA, 5.60 g of DBTO, and 28.0 mg of 4H-TEMPO were stirred and heated to 110°C. Only the methanol generated by the reaction was distilled off, and the transesterification reaction was performed for 6 hours. MMA was distilled off from the obtained reaction solution to obtain dimethacrylate of a 4-mole adduct of neopentyl glycol with ethylene oxide. This is referred to as compound (M-2).

[0191] When the content of sulfur atoms contained in the obtained compound (M-2) was measured by ICP, no sulfur atoms were observed.

Abstract

The present invention provides a radiation-curable composition which can provide a cured product capable of sufficiently satisfying all of light resistance, transparency and curability and therefore can be useful in much more applications in addition to optical members, lighting members, and automobile members. A radiation-curable composition used after cured by radiation energy, wherein a cured product produced by curing the curable composition by radiation energy of 2 J / cm <2> satisfies: an initial light transmittance of 80% or more at a wavelength of 380 nm, and a light transmittance retention of 90% or more after 200 hours of accelerated light resistance test.

Description

Technical field [0001] The present invention relates to ionizing radiation curable compositions and cured products. In more detail, the present invention relates to ionizing radiation curable compositions that are widely used in various applications such as optical components (optical display devices), lighting components (lighting appliances), automotive components (vehicle components), building materials, optical components, etc. . Background technique [0002] The ionizing radiation curable composition is a curable composition used for curing by ionizing radiation energy such as electromagnetic waves, ultraviolet rays, visible rays, infrared rays, electron rays, and gamma rays, and because it is compared with transparent inorganic materials such as glass, it is molded and processed Because of its excellent performance, it is widely used in various applications such as optical components, lighting components, and automotive components. In these applications, for light derived...
