PROBLEM TO BE SOLVED: To obtain a compsn. having an excellent adhesion strength and an excellent peeling strength in particular as well as a good adhesion speed by blending a compd. having aβ-diketone structure with a 2-cyanoacrylate or a compsn. having a 2-cyanoacrylate as a main component. SOLUTION: This compsn. is formed by blending 10-10,000 ppm by wt. of aβ-diketone compd. represented by the formula, a curing accelerator, an adhesion increasing agent, an anionic polymerization inhibitor, a radical polymerization inhibitor, etc., with a 2-cyanoacrylate or a compsn. having a 2-cyanoacrylate as a main component. Examples of the 2-cyanoacrylate are methyl-2- cyanoacrylate, butyl-2-cyanoacrylate, etc. Examples of the diketone compd. are 4,4,4-trifluoro-1-(2-furyl)-1,3-butanedione, 4,4,4-trifluoro-1-(4H-pyran-2-yle)-1,3- butanedione, etc. In the formula, Ar is a heterocyclic ring contg. an oxygen atom; and Rf is a perfluoroalkyl group.
