(Prior art) α-N cyanoacrylate, which has been conventionally used as an adhesive composition, has the general formula CH,=C-C00R.
' (In the formula, R' represents alkyl, alkenyl, aralkyl, haloalkyl, cyclohexyl, phenyl, etc. having 16 or less carbon atoms), which easily undergoes anionic polymerization and is free from moisture adhering to the solid surface. It has the property of being polymerized and cured in a very short time of several seconds to several minutes at room temperature without using a catalyst by various anion active substances such as atmospheric humidity and other alkaline substances. Therefore, it has been widely used as an instant adhesive for industrial, medical, and general household purposes.

(Problems to be Solved by the Invention) However, this α-cyanoacrylate adhesive has the disadvantage that the set time is significantly slow if the surface of the adherend is acidic or has low moisture content. However, when the adherend is, for example, a wood material, a zinc chromate plated steel plate, polyester, Bakelite, EPDM, etc., there are problems in that the setting time is significantly slow and the adhesive strength is also low.

The amount of these compounds to be added is particularly preferably in the range of 0.01 to 1 part by weight per 100 parts by weight of α-cyanoacrylate.If added in excess of this range, the setting time will be slow due to warping, and the viscosity will increase. On the other hand, if the amount is less than o or oi parts by weight, the curing acceleration will be insufficient and the setting time and adhesive strength will not be improved. In addition, in the above general formula (1), when the integer n is less than 4, the effect of accelerating the set time is poor, while when it exceeds 100, there is a drawback that the solubility in α-sia and noacrylate monomers becomes poor. .
