Problems solved by technology

[0008] However, there is also no description in this document of the relationship between the hard coat layer and the cracking of the glass material.
In addition, even if the optical film is used as an anti-scattering film, glare will occur in a high-definition display device

Embodiment 1

[0220] A PET film (Mitsubishi Plastics Co., Ltd., PET, thickness 75 μm) was used as the transparent resin layer, and the AWM layer coating liquid AWM-1 was coated on the film with a wire bar coater #10, and then the coating was carried out at 80°C. Let dry for 1 minute. Pass the coating film through an ultraviolet irradiation device (manufactured by Ushio Co., Ltd., high-pressure mercury lamp, ultraviolet irradiation amount: 100mJ / cm 2 ) and UV-cured to form an AWM layer with a surface concave-convex structure. The thickness of the AWM layer in the obtained transparent laminated film was about 3 μm.

Embodiment 2～9 and comparative example 1～4

[0222] A transparent multilayer film was produced in the same manner as in Example 1 except that AWM-2 to 13 were respectively used instead of AWM-1 as the AWM layer coating liquid.

[0223] Table 1 shows the evaluation results of the transparent laminated films obtained in Examples 1-9 and Comparative Examples 1-4.

[0224]

Embodiment 10

[0226] On the AWM layer of the transparent laminate film obtained in Example 4, the low-refractive-index layer coating liquid LC was applied using a wire bar coater #4, and dried at 70° C. for 1 minute. Then, the coating film was passed through an ultraviolet irradiation device (manufactured by Ushio Co., Ltd., high-pressure mercury lamp, ultraviolet irradiation amount: 100mJ / cm 2 ) were subjected to UV curing to form a low refractive index layer. The thickness of the low-refractive index layer in the obtained low-reflection transparent laminated film was about 100 nm.

Abstract

A transparent layered film produced by forming, on one surface of a transparent resin layer, an anti-water-mark layer that is constituted of a cured object of a curable composition comprising a curable resin, a thermoplastic resin, and metal oxide particles with an average primary-particle diameter of 1-100 nm and forming, in the surface of the anti-water-mark layer, a rugged structure which has an arithmetic average roughness (Ra) of 0.005 [mu]m or greater but less than 0.03 [mu]m, an average distance (Sm) between the irregularities of 50-300 [mu]m, an arithmetic average inclination (delta a) less than 0.1 DEG, and a ten-point average roughness (Rz) less than 0.2 [mu]m. When a glass to which the film has been laminated is used in the upper electrode of a touch panel display, not only glass fragment scattering due to breakage of the upper electrode can be inhibited, but also the generation of water marks is prevented and the display device even with high resolution can be inhibited from glittering.

Description

technical field [0001] The present invention relates to a transparent multilayer film for preventing scattering of glass shards caused by breakage, and a method for producing the same, and a touch panel device disposed inside an upper electrode (transparent electrode on the viewing side) of a touch panel display made of glass. electrode. Background technique [0002] With the advancement of electronic displays as human-computer interaction, interactive input systems have become popular. Among them, devices that integrate touch panels (coordinate input devices) and displays have been widely used in ATMs (cash automatic teller machines), commodity Management, outworking (social, sales), wayfinding, entertainment equipment, etc. Lightweight / thin displays such as liquid crystal displays do not need to use a keyboard, and the use of touch panels in mobile devices is also increasing from the perspective of effectively utilizing their features. A touch panel is a device that inpu...
