Description of the Related Art Acrylic adhesives have excellent properties such as aging resistance, water resistance, and flexibility, and are made of wood, metal, rubber, glass, leather, and the like. Widely used for bonding between same or different types of paper, fiber, etc. Such a conventional acrylic adhesive is obtained by copolymerizing different acrylic monomers, or by adding another vinyl monomer to the acrylic monomer, for example, vinyl chloride, styrene, vinyl acetate, vinylidene chloride, acrylonitrile, vinylpyridine. And a methacrylic acid ester or the like, and a polymer obtained by adding a polybutadiene rubber or a butadiene-styrene copolymer to an acrylic monomer to improve its properties is used as an adhesive main agent. However, no practical acrylic adhesive using an acrylic homopolymer as an adhesive main agent has been proposed. This is presumably due to the relatively high crystallinity of the acrylic-based homopolymer, when used as an adhesive base material is caused to allowed to decrease adhesion molecule cohesive strength of the adhesive itself the worker becomes large It is.

Examples thereof include bifunctional acid anhydrides such as pyromellitic anhydride, free acid anhydrides such as trimellitic anhydride, polyphenols, and polymercaptans. The amount of the curing agent may be generally selected in the range of 0.07 to 1.2 parts by weight based on 100 parts by weight of the acrylic homopolymer. If the amount of the curing agent is less than 0.07 parts by weight, curing will be insufficient, and if it exceeds 1.2 parts by weight, the cured product will become brittle and the adhesive strength tends to decrease. In addition,
A known curing accelerator such as ethylene thiourea, benzoyl thiourea, L-ascorbic acid, thiosalicylic acid may be mixed with an appropriate amount of the curing agent.

The compounding amount of the metal ion compound is usually preferably selected in the range of 0.05 to 1.2 parts by weight based on 100 parts by weight of the acrylic homopolymer. If the amount is less than 0.05 parts by weight, the improvement of the adhesiveness becomes insufficient and it is difficult to obtain a predetermined adhesive strength. Even if the amount is more than 1.2 parts by weight, the effect is not changed. When such a metal ion compound is added to the acrylic homopolymer together with the curing agent, it is not known what mechanism improves the adhesiveness, but the metal in the form of fine powder contains gold in the adhesive system. It is believed that it becomes a metal ion and acts as a catalyst at the time of curing, thereby activating the curing actively, suppressing the molecular cohesion of the polymer, and increasing the adhesive strength.
