Problems solved by technology

However, this method has a problem in that if the peeling process is not carried out at a high temperature in the manufacturing process, cracks will occur.
However, this transparent substrate has a problem that the plate is easily cracked in the step of peeling from the cell after polymerization and curing.

Embodiment 1

[0144] In 10 parts of isostearyl methacrylate ("NK ester S-1800M" manufactured by Shin Nakamura Chemical Industry Co., Ltd.), 10 parts of methyl methacrylate and bis (oxymethyl) tricyclo [5, 2, 1 ,0 2,6 ] In 100 parts of a mixture of 80 parts of decane dimethacrylate, 0.05 parts of 2,2'-azobis(2,4-dimethyl-4-methoxyvaleronitrile) as a polymerization initiator were mixed, 0.05 part of tert-butyl peroxy pivalate, 0.05 part of tert-hexyl peroxy isopropyl carbonate and 0.03 part of terpinolene as a polymerization regulator, and the resulting mixture is put into a suction filter bottle, stirred, and vacuum removed gas to obtain a polymerization mixture.

[0145] The polymerization mixture was poured into a mold formed by inserting a gasket between a pair of tempered glass sheets at a distance of 1.7mm, and air bubbles were removed, and then placed in a heating furnace, and polymerized at 55°C for 1 hour, then at 50°C for 1 hour, and then heated at 135°C Polymerized for 3 hours. ...

Embodiment 2~24

[0147] [Examples 2-24, Comparative Examples 1-9]

[0148] Except having used the raw material composition shown in Tables 1-6, it carried out similarly to Example 1, and produced the acrylic resin board. The evaluation results are shown in Tables 1-6.

Embodiment 25

[0150] In Example 1, 0.05 part of n-dodecyl mercaptan was further added as a chain transfer agent to the polymerization mixture, and the rest was carried out in the same manner as in Example 1 to produce an acrylic resin plate. The evaluation results are shown in Table 7. Moreover, bis(oxymethyl)tricyclo[5,2,1,0 2,6 ] The residual monomer amount of decane dimethacrylate was 2.09%.

Abstract

A process for the production of acrylic resin boards by polymerizing and curing a polymerizable mixture which comprises 100 parts by mass of a mixture comprising an alkyl methacrylate wherein the alkyl has 1 to 4 carbon atoms and a polyfunctional (meth)acrylate, 0.001 to 1 part by mass of a polymerization initiator having a ten-hour half-life temperature of 80 DEG C or above, and 0.015 to 0.2 part by mass of cyclohexadiene or a terpenoid; an acrylic resin comprising 3 to 30 % by mass of alkyl methacrylate units wherein the alkyl has 8 to 20 carbon atoms, 2 to 35 % by mass of monoethylenically unsaturated monomer units comprising alkyl methacrylate units wherein the alkyl has 1 to 4 carbon atoms, and 35 to 95 % by mass of polyfunctional (meth)acrylate units; resin boards made from this resin and a process for the production thereof; and transparent electrode boards for touch panels and touch panels, made by using the above resin boards.

Description

technical field [0001] The present invention relates to an acrylic resin excellent in heat resistance, appearance, and shape stability, a resin plate made of the acrylic resin, and a transparent electrode for a touch panel having a transparent substrate excellent in heat resistance, transparency, and conductive film adhesion Plates, touch panels with the transparent electrode plates and their manufacturing methods. Background technique [0002] <Acrylic resin board> [0003] Acrylic resin sheets are used in lenses, automotive parts, lighting components, various electronic displays, etc. due to their excellent optical properties. However, when the acrylic resin plate is heat-treated at high temperature, it has a disadvantage of insufficient heat resistance. [0004] As a technique for improving the heat resistance of an acrylic resin sheet, there is a method of introducing a crosslinked structure by adding a polyfunctional monomer during polymerization of methyl metha...
