Embodiment

[0135] Hereinafter, the present invention will be described in more detail with reference to experimental examples, but the present invention is not limited thereto.

experiment example

[0137] Unless otherwise mentioned, experiments were performed at 23°C. Curable resin compositions having the compositions shown in Table 1 and Table 2 were prepared and evaluated. Table 3 and Table 4 show the results.

[0138] As each component in the curable resin composition described in the experimental example, the following compounds were selected.

[0139] In addition, KRM-8776 of a table|surface describes the quantity of the urethane acrylate contained in "KRM-8776" manufactured by Daicel-Cytec. NOAA in the table describes the amount of n-octyl acrylate contained in "KRM-8776" manufactured by Daicel-Cytec. When "KRM-8776" manufactured by Daicel-Cytec was not used, n-octyl acrylate manufactured by Osaka Organic Chemicals Co., Ltd. was used.

[0140]

[0141] As the polyfunctional (meth)acrylate of (A) component, the following compounds are selected.

[0142] (A-1) Polyester-type urethane acrylate oligomer ("KHP-11" manufactured by Negami Kogyo Co., Ltd., the struct...

Abstract

Provided is a composition having superior curability of deep sections. The composition contains the belowmentioned (P) and (C) to (F): (P) a curable vinyl monomer, (C) a photoinitiator, (D) an antioxidant, (E) a thiol, and (F) a dicarboxylic acid diester.

Description

technical field [0001] The present invention relates to compositions. Background technique [0002] Touch panels mounted on displays such as LCDs (liquid crystal displays) include resistive film types, capacitive types, electromagnetic induction types, and optical types. On the surface of these touch panels, a design decorative plate for improving the appearance or an icon sheet (icon sheet) for designating a touched position may be pasted. The capacitive touch panel has a structure in which transparent electrodes are formed on a transparent substrate, and a transparent plate is bonded on the transparent electrodes. [0003] Conventionally, adhesives have been used for bonding a decorative board to a touch panel, bonding an icon sheet to a touch panel, and bonding a transparent substrate to a transparent plate. [0004] In these icon sheets or touch panels, only the display area can be seen in order to hide the driving IC and wiring of the display body, or the frame sealan...
