Embodiment

[0174] Hereinafter, although an Example demonstrates this invention, this invention is not limited to these Examples.

[0175] test methods

[0176] (1) Total light transmittance

[0177] The total light transmittance was measured using a nephelometer "NDH2000" (trade name) of Nippon Denshoku Kogyo Co., Ltd. in accordance with JIS K7361-1:1997.

[0178] (2) Haze

[0179] According to JIS K7136:2000, the haze was measured using the turbidity meter "NDH2000" (brand name) of Nippon Denshoku Kogyo Co., Ltd..

[0180] (3) Yellowness Index

[0181] According to JIS K7105:1981, the yellowness index was measured using the colorimeter "SolidSpec-3700" (trade name) of Shimadzu Corporation.

[0182] (4) Pencil hardness

[0183] According to JIS K5600-5-4, the pencil hardness was measured using the pencil "ユニ" (trade name) of Mitsubishi Pencil Co., Ltd. under the condition of a load of 750 g.

[0184] (5) Shrinkage start temperature (heat-resistant dimensional stability)

example 1

[0238] Use above-mentioned (α-1), use to have 50mm extruder (install the W type screw thread of L / D=29, CR=1.86); The T type die head of die head width 680mm; ) and a mirror belt (second mirror body) to squeeze the melted film into a traction coiler to obtain a film with a thickness of 500 μm and a good surface appearance. At this time, the setting conditions are set temperature C1 / C2 / C3 / AD=280 / 300 / 320 / 320°C of the extruder; set temperature of the T-shaped die head is 320°C; 1.0mm; the set temperature of the mirror roller is 140°C; the set temperature of the mirror belt is 120°C; the extrusion pressure of the mirror belt is 1.4MPa; the pulling speed is 3.6m / min. Total light transmittance, haze and yellowness index were measured. The results are shown in Table 1. Next, after corona discharge treatment was applied to both surfaces of the obtained film, a hard coat layer was formed on one surface to have a thickness of 25 μm after curing using the above-mentioned (γ2-1) using a...

example 2

[0240] Formation of the hard-coat laminated film and evaluation of physical properties were performed in the same manner as in Example 1 except that the above-mentioned (α-2) was used instead of the above-mentioned (α-1). The results are shown in Table 1.

Abstract

One aspect of the present invention is a hard coat laminate film having a total light transmittance of 80% or more and having (gamma) a hard coat on at least one surface of (alpha) an aromatic-polycarbonate resin film containing 30 mol% or more of a structural unit derived from 4,4'-(3,3,5-trimethylcyclohexane-1,1-diyl)diphenol when the total of the structural units derived from aromatic dihydroxy compounds is 100 mol%. Another aspect of the present invention is a hard coat laminate film having a total light transmittance of 80% or more and having (gamma) a hard coat on at least one surface of a transparent laminate film constituted of (alpha) an aromatic-polycarbonate resin film containing 30 mol% or more of a structural unit derived from 4,4'-(3,3,5-trimethylcyclohexane-1,1-diyl)diphenol, when the total of the structural units derived from aromatic dihydroxy compounds is 100 mol%, and (beta) a poly(meth)acrylimide resin film.

Description

technical field [0001] The present invention relates to a hard coat laminated film. More specifically, the present invention relates to a laminated film of an aromatic polycarbonate resin film excellent in heat resistance and a hard coat layer. Background technique [0002] In recent years, touch panels installed on image display devices such as liquid crystal displays, plasma displays, and electroluminescence displays, and capable of performing input by touching with a finger, a pen, etc. while viewing a display, have become widespread. [0003] In addition, in image display devices (including image display devices with a touch panel function and image display devices without a touch panel function.) Forming circuits and substrates on which various components are arranged, from the aspects of heat resistance, dimensional stability, In view of the required properties such as high transparency, high surface hardness, and high rigidity, articles based on glass are used.
