Problems solved by technology

The ultraviolet absorber described in Japanese Patent Laid-Open No. 2010-132846 describes the following content: Since a high ultraviolet absorbing effect can be obtained with a small amount, it is different from the conventionally known method of adding an ultraviolet absorber to a resin molded product in a larger amount. Compared with the case, it is difficult to show the influence on the physical properties of the resin molded product due to the addition of the ultraviolet absorber

Embodiment 1

[0296] (formation of resin layer)

[0297] The pellets of polyethylene terephthalate (PET) dried at 160°C for 8 hours and the compound (A) having the following structure as a compound represented by the general formula (1) were mixed and put into extrusion machine. Melt-kneading was carried out at a melting temperature of 280° C. to prepare a masterbatch containing pellets as the compound (A).

[0298] After that, PET pellets dried at 160° C. for 8 hours were mixed with the compound (A)-containing pellet masterbatch obtained above so that the content of the compound (A) in the resin layer became 0.7% by mass, and mixed at 280° C. Melt-kneading was carried out at °C, and a resin layer as a film with a thickness of 100 μm was formed by a melt extrusion method.

[0340] (formation of resin layer)

[0341] The pellets of polyethylene terephthalate (PET) dried at 160° C. for 8 hours and the compound (A) having the above structure were mixed and charged into an extruder. Melt-kneading was carried out at a melting temperature of 280° C. to prepare a masterbatch containing pellets of the compound (A) (compound (A) containing masterbatch pellets).

[0342] After that, PET pellets dried at 160° C. for 8 hours and a masterbatch containing pellets as compound (A) were mixed in such a ratio that the content of compound (A) in the resin layer became the amount described in the following Table 5, and mixed at 280° C. Melt-kneading was carried out at °C, and a resin layer as a film with a thickness of 100 μm was formed by a melt extrusion method.

[0343] (formation of protective layer)

[0344] On the surface of the resin layer obtained above, the protective layer 1 containing an acrylic resin was formed by the following method.

Embodiment 11

[0350] A resin layer having a thickness of 100 μm was formed in the same manner as in Example 1.

[0351] A protective layer containing polysiloxane was formed on the surface of the obtained resin layer by a sol-gel method.

[0352] That is, first, the components shown in the following Table 6 were mixed to prepare a polysiloxane-containing composition for forming a protective layer.

[0353] Specifically, stirring the aqueous acetic acid solution, 3-glycidoxypropyltrimethoxysilane was dropped into the aqueous acetic acid solution over 3 minutes. Next, tetraethoxysilane was added to the aqueous acetic acid solution over 3 minutes while stirring. Next, stirring was continued for 2 hours. Next, colloidal silica, a chelating agent, and a surfactant were sequentially added to prepare a polysiloxane-containing composition for forming a protective layer.

Abstract

Provided are a resin molded body and applications thereof, wherein the resin molded body is provided with: a resin layer that contains a resin and a compound represented by general formula (1); and, on at least one of the surfaces of the resin layer, a protective layer that contains at least one substance selected from a group consisting of urethane resins, acrylic resins, and polysiloxane. In general formula (1), Het1 represents an aromatic heterocyclic residue having a bivalent five-membered or six-membered ring. Each of Xa, Xb, Xc, and Xd represents, independently of each other, a hetero atom, and each of Ya, Yb, Yc, Yd, Ye, and Yf represents, independently of each other, a hetero atom or a carbon atom. The ring bonded to Het1 may have a double bond at an arbitrary position.

Description

technical field [0001] The present disclosure relates to a resin molded body and a blue light cut laminated body. Background technique [0002] Image display devices such as cathode ray tube display devices, plasma displays, electroluminescent displays, fluorescent displays, field emission displays, and liquid crystal displays (Liquid Crystal Display; LCD), or smartphones and tablet terminals equipped with touch panels, etc. Among various displays, the screen of the display provided with a light source is used for visual viewing. [0003] In recent years, attention has been paid to the influence of ultraviolet rays and blue light on the retina when image display devices and small terminals equipped with touch panels are used for a long period of time. In addition, it is also desired to reduce the influence of ultraviolet rays and blue light on the retina in large displays and the like. [0004] In order to reduce the influence of near ultraviolet light and blue light (here...
