ープ状に細断したり、磁気テープを接合する際に
使う刃を磨損させることが多かつた。 Conventional cleaning tapes include abrasive materials such as alumina (Al 2 O 3 ), silicon carbide (Sic), chromium oxide (Cr 2 O 3 ), and red iron (α-Fe 2 O 3 ) on a support along with a binder. It is known to provide a cleaning layer by coating. Although these cleaning layers have sufficient ability to remove dirt, their abrasive ability is too strong, so they often wear out the heads and guide poles. The blades used for this purpose were often worn out.
かかる欠点を防止するために、研磨材に代えて
支持体表面をサンドブラスト処理などによりマツ
ト化する方法が提案された（実公昭49−42726
号）。しかし、この方法で得られる表面凹凸には
限度があり、またしばしば支持体の破断強度が低
下する。 In order to prevent such drawbacks, a method was proposed in which the surface of the support was made matte by sandblasting instead of using an abrasive material (Japanese Utility Model Publication No. 49-42726).
issue). However, there are limits to the surface roughness that can be obtained with this method, and the breaking strength of the support is often reduced.
従つて、本発明の目的は、第１に優れたクリー

ことにあり、第２に、優れた耐磨損性を持つクリ
ーニングテープを提供することにある。 Accordingly, an object of the present invention is, firstly, to provide a cleaning tape with excellent cleaning effects, and secondly, to provide a cleaning tape with excellent abrasion resistance.
本発明の上記の目的は、支持体の片面又は両面
にバインダー及び樹脂粒子からなるクリーニング
層を設けてなるクリーニングテープによつて達成
される。 The above object of the present invention is achieved by a cleaning tape comprising a support and a cleaning layer comprising a binder and resin particles on one or both sides.
本発明のクリーニング層に使用される樹脂粒子
としてはポリスチレン、ポリエチレン、ポリエス
テル、フエノール樹脂、尿素樹脂、メラメン樹
脂、エポキシ樹脂、フエノキシ樹脂等がある。 Examples of resin particles used in the cleaning layer of the present invention include polystyrene, polyethylene, polyester, phenol resin, urea resin, melamen resin, epoxy resin, and phenoxy resin.
これら樹脂粒子の粒子サイズは5μ以上であり、
好ましくは10μ〜200μ位のものが目的に応じて利
用される。 The particle size of these resin particles is 5μ or more,
Preferably, those with a diameter of about 10μ to 200μ are used depending on the purpose.
樹脂粒子は、支持体上に保存されるために、バ

混合物は支持体の片面又は両面の全面又は一部分
に塗布される。 The resin particles are stored on a support using a binder (e.g., vinyl chloride-vinyl acetate resin, vinylidene chloride resin, methacrylic resin, nitrocellulose, water-soluble polymer (e.g., polyvinyl alcohol), polyethylene latex, etc.). ) are mixed. The mixture thus obtained is applied to all or part of one or both sides of the support.
塗布に用いる溶剤は樹脂粒子を溶解しないもの
であればよく、たとえば、メチルエチルケトン、
トルエン、メチルエチルケトン−トルエン混合溶
剤などが用いられる。 The solvent used for coating may be any solvent that does not dissolve the resin particles, such as methyl ethyl ketone,
Toluene, methyl ethyl ketone-toluene mixed solvent, etc. are used.

る。 The cleaning tape of the present invention can be used as an abrasive tape or a leader tape, and since the resin particles are dispersed and fixed on the support surface, dirt adhering to the head and guide can be efficiently removed without damaging them. can do. Furthermore,
The cleaning tape of the present invention also has the advantage of not reducing its own breaking strength, unlike cleaning tapes obtained by conventional sandblasting methods.
以下に実施例を示し、本発明を詳細に説明す
