【発明の詳細な説明】
（イ）発明の目的
〔産業上の利用分野〕
本発明は一液型接着剤に関するものであり、特に増粘さ

性を付与した嫌気性接着剤に関するものである。Detailed Description of the Invention (a) Purpose of the Invention [Field of Industrial Application] The present invention relates to a one-component adhesive, which is particularly thickened, has a high adhesion speed, is a room-temperature curing adhesive, and has a short pot life. It also relates to an anaerobic adhesive that has been given coatability by forming it into an aqueous composition.
この接着剤は、ドライタッチに仕上げることができるた
めネジのゆるみ止め用接着剤或いは積層板のフィルム型
接着剤として好適なものである。Since this adhesive can be finished to a dry touch, it is suitable as an adhesive for preventing loosening of screws or a film-type adhesive for laminated boards.

はアクリロイル基及び／又はメタクリロイル基を有する
単量体（以下「（メタ）アクリレート単量体」と称する
。）を主成分とする嫌気硬化性組成物が用いられてきた
。Conventionally, one-component room-temperature-curing adhesives that harden rapidly include anaerobic adhesives whose main component is a monomer having an acryloyl group and/or a methacryloyl group (hereinafter referred to as "(meth)acrylate monomer"). Curable compositions have been used.
従来の嫌気硬化性組成物は機械的に混合されん各成分か

険性、不安定なポットライフ性、被着剤の選択性或いは
不適当な粘性による塗工不良性などの欠点を有していた
。Conventional anaerobic curable compositions consist of components that are not mechanically mixed, and are oily in the presence of substantial oxygen;
It is a composition that hardens rapidly with uncontrollable viscosity when substantially shielded from oxygen. For this reason, before curing, components such as oil-based (meth)acrylate monomers, peroxides, or amines, which are the main curing accelerator, pose a risk of chemical damage, unstable pot life, and damage to the adhesive. However, it has drawbacks such as poor coating properties due to poor selectivity and inappropriate viscosity.

Furthermore, after drying, the peroxide, which is the main component of the catalyst system, is encapsulated. Since the (meth)acrylate monomer does not undergo a curing reaction, it forms an oil layer on the surface of the adherend, and a dry film is formed on the surface due to the pre-existing polymer.
