やシーケンサ−へ供給する方法が増えている。In recent years, with the miniaturization of electrical equipment and the rationalization and labor saving of manufacturing processes, electronic components such as resistors and capacitors are fixed on adhesive tape in a predetermined order and then supplied to automatic electronic component insertion machines and sequencers. There are more ways to do it.
従来、これらに使用する粘着テープの粘着剤として、ア

ている。Generally, acrylic adhesives include butyl acrylate and 2-
By copolymerizing a heptamer with a low glass transition temperature such as ethylhexyl acrylate and a heptamer with a high glass transition temperature such as vinyl acetate or methyl methacrylate,
Furthermore, crosslinking monomers such as acrylic acid and hydroxymethyl methacrylate are added to balance the adhesive strength.
一方、ゴム系粘着剤の場合は天然ゴムや合成ゴムなどの
ゴム成分に種々の粘着付与剤を配合することにより物性
のバランスをとっている。On the other hand, in the case of rubber-based adhesives, the physical properties are balanced by blending various tackifiers with rubber components such as natural rubber and synthetic rubber.
ところが、これらの粘着剤は接着強度が短時間で大きく
なるため、電子部品をテープから再剥離することが必要

う欠点を有していた。However, the adhesive strength of these adhesives increases in a short period of time, so when it is necessary to re-peel the electronic component from the tape, the adhesive transfers to the surface of the adherend, making re-peelability easier ( It had the disadvantage that adhesive strength could not be obtained in the initial stage if it was attempted to be bonded.

う問題を有していた。As a method of imparting such contradictory properties, a multifunctional photosensitive monomer such as trimethylolpropane triacrylate C2 is added to the adhesive component, and the adhesive is cross-linked and cured by irradiation with ultraviolet rays, etc. A peeling method is known.However, this method also has the problem that sufficient effects cannot be obtained in terms of initial adhesive strength and removability.
そこで本発明者らは以上のような欠点を解決するべく鋭

有してもよい。Acrylic rubber, which is the non-adhesive component used in C2 of the present invention, is a polymer whose main component is acrylic ester, and has excellent heat resistance, aging resistance, and weather resistance (= excellent resistance to organic solvents). It has good solubility.Saturated polyester resin also has excellent light resistance, abrasion resistance, adhesion, etc.Furthermore, by adding a crosslinking agent such as isocyanate to this non-adhesive component, these properties can be further improved. These non-stick ingredients may also include rosin,
A tackifier such as a terpene resin or a hydrocarbon resin may be included as appropriate.

Therefore, by using this urethane (meth)acrylic resin, it has high crosslinking properties, and after curing, it forms a film with excellent scratch resistance, and can be used for both light and heat reactions.
It has excellent properties such as good adhesion to PET (polyethylene terephthalate), etc.
