Description
本発明は、樹脂組成物に関する。本発明は、例えば、接着剤、ハードコート剤とそれを用いた電子デバイスに関する。 The present invention relates to a resin composition. The present invention relates to, for example, an adhesive, a hard coat agent, and an electronic device using the same.
LCD等の表示体の上に搭載するタッチパネルには、抵抗膜式、静電容量式、電磁誘導式、光学式等がある。これらのタッチパネルの上には、化粧板やアイコンシートを貼り合わせる場合がある。化粧板は、見た目のデザイン性を良くするために使用する。アイコンシートは、タッチする位置を指定するために使用する。静電容量式タッチパネルは、透明基板の上に透明電極を形成し、その透明電極の上に透明板を貼り合わせた構造を有している。 Examples of touch panels mounted on a display body such as an LCD include a resistance film type, a capacitance type, an electromagnetic induction type, and an optical type. A decorative board or an icon sheet may be pasted on these touch panels. The decorative board is used to improve the visual design. The icon sheet is used to specify a touch position. The capacitive touch panel has a structure in which a transparent electrode is formed on a transparent substrate, and a transparent plate is bonded to the transparent electrode.
従来は、上記の化粧板とタッチパネルとの貼り合わせ、アイコンシートとタッチパネルとの貼り合わせ、静電容量式タッチパネルにおける透明電極を形成した透明基板と透明板との貼り合わせを、シート状の両面粘着シートを用いて行うか、被着体の片面に粘着加工するかして、行っていた。このような粘着剤を使用する技術では、接着が不十分であったり、貼り合わせ面に気泡が混入したりするという問題があった。特に、貼り合わせ面に印刷加工がしてあると、印刷のあるところとないところの段差部分に気泡が残りやすいという問題があった。 Conventionally, bonding of the decorative plate and the touch panel, bonding of the icon sheet and the touch panel, and bonding of the transparent substrate on which the transparent electrode is formed in the capacitive touch panel and the transparent plate are performed by sheet-like double-sided adhesive. This is done by using a sheet or by performing adhesive processing on one side of the adherend. In the technique using such a pressure-sensitive adhesive, there is a problem that adhesion is insufficient or bubbles are mixed into the bonding surface. In particular, when printing is performed on the bonding surface, there is a problem that bubbles are likely to remain in the stepped portions where printing is performed and where printing is not performed.
近年、LCD等の表示体のガラスの厚さが薄くなってきている。ガラスが薄くなると外部応力でLCDが変形しやすくなる。この薄いガラスのLCD等の表示体と、アクリル板やポリカーボネート板等の光学機能材料とを貼り合わせる場合、ガラスとアクリル等の線膨張の違いや、アクリル板やポリカーボネート等のプラスチック成型材の成型時の歪みにより、耐熱試験や耐湿試験において成型歪みの緩和や吸湿・乾燥が起こり、寸法変化や反り等の面精度変化が起きる。従来の接着剤(例えば、特許文献1〜2)でこの変形を抑えようとした場合、接着面が剥がれたり、LCDが割れたり、LCDが表示ムラになったりするという問題点があった。 In recent years, the thickness of glass of display bodies such as LCDs has been reduced. When the glass becomes thinner, the LCD is easily deformed by external stress. When this thin glass LCD or other optical display material is bonded to an optical functional material such as an acrylic plate or a polycarbonate plate, the difference in linear expansion between the glass and acrylic or the molding of a plastic molding material such as an acrylic plate or polycarbonate Due to this distortion, mold distortion is relaxed and moisture absorption / drying occurs in the heat resistance test and moisture resistance test, and surface accuracy changes such as dimensional changes and warpage occur. When trying to suppress this deformation with a conventional adhesive (for example, Patent Documents 1 and 2), there are problems that the adhesive surface is peeled off, the LCD is cracked, or the LCD becomes uneven in display.
上記のような問題点の解決策として、特許文献3のようなUV硬化型樹脂がある。これはイソボルニル(メタ)アクリレートのような剛直な骨格モノマーをベースとした高弾性樹脂であるが故に、高温信頼性試験において被着体の膨張収縮に耐えることができず剥がれを生じてしまう可能性があった。 As a solution to the above problems, there is a UV curable resin as in Patent Document 3. Because this is a highly elastic resin based on a rigid skeletal monomer such as isobornyl (meth) acrylate, it cannot withstand the expansion and contraction of the adherend in a high-temperature reliability test and may cause peeling. was there.
本発明は、例えば、タッチパネル等の表示体に使用される化粧板やアイコンシートを貼り合わせる場合や、静電容量タッチパネルにおける透明電極を形成した透明基板と透明基板とを貼り合わせる場合に、十分な接着性を付与し、気泡を含まずに貼り合わせることが困難であるという従来技術の問題点を解決する接着剤、ハードコート剤の提供である。本発明は、例えば、表示体と光学機能材料とを貼り合わせた場合に、接着面が剥がれたり、表示体のガラスが割れたりする従来技術の問題点を解決する接着剤、ハードコート剤の提供である。 The present invention is sufficient when, for example, a decorative plate or icon sheet used for a display body such as a touch panel is bonded, or when a transparent substrate on which a transparent electrode is formed in a capacitive touch panel is bonded to a transparent substrate. The present invention provides an adhesive and a hard coat agent that imparts adhesiveness and solves the problems of the prior art that it is difficult to bond without containing bubbles. The present invention provides, for example, an adhesive and a hard coat agent that solve the problems of the prior art in which, when a display body and an optical functional material are bonded together, the adhesive surface peels off or the glass of the display body is broken. It is.

JIS K 6850に従い測定した。被着材としてポリカーボネート板(25mm×25mm×2mm)を用いた。接着部位を8mmφ(接着部位を8mmφとは、接着部位が直径8mmの円であることをいう)として、樹脂組成物を用い、2枚のポリカーボネート板を貼り合わせた。無電極放電ランプを使用したフュージョン社製硬化装置により、365nmの波長の積算光量2000mJ/cm2の条件にて硬化させ、引張せん断接着強さ試験片を作製した。試験片は、万能試験機を使用して、温度23℃、湿度50%の環境下、引張速度10mm/minで引張せん断接着強さを測定した。(Tensile shear bond strength to polycarbonate (bond strength, polycarbonate))
It measured according to JIS K 6850. A polycarbonate plate (25 mm × 25 mm × 2 mm) was used as the adherend. The adhesive part was 8 mmφ (the adhesive part is 8 mmφ means that the adhesive part is a circle having a diameter of 8 mm), and two polycarbonate plates were bonded together using the resin composition. A tensile shear bond strength test piece was prepared by curing with a curing device manufactured by Fusion Corporation using an electrodeless discharge lamp under conditions of an integrated light quantity of 2000 mJ / cm 2 with a wavelength of 365 nm. The test piece was measured for tensile shear bond strength at a tensile speed of 10 mm / min in an environment of a temperature of 23 ° C. and a humidity of 50% using a universal testing machine.
