Furthermore, the above-mentioned compounding ratio of the A agent and the B agent is based on the theoretical number of epoxy equivalents of the epoxy resin contained in the A agent and the number of active hydrogen equivalents in the so-called curing agent component contained in the B agent. It can be determined by combining, but usually 0.5:1 to 1:2
An equivalent ratio within the following range is appropriate. However, it is understood that the above-mentioned addition ratio and compounding ratio do not limit the present invention in any way, and even if it deviates from such range, it is still within the scope of the present invention as long as it meets the purpose of the present invention. .

Here, the above addition ratio indicates one embodiment of the present invention, and in particular, as for the method of adding the thermoplastic elastomer, if addition to agent B is possible, addition to both agents A and B is also prevented. Generally speaking, it is sufficient to add it to at least one of agent A or agent B, although it is not a
Even if it is added to the B agent, the addition ratio may be approximately the same as above. However, when it is added to both agents A and B, it goes without saying that the total amount should be approximately at the above-mentioned addition ratio.

性の低下が顕著となるので、いずれも好ましくない。[0016] If the addition ratio of the epoxy resin (a-1) or the poamide resin is smaller than the above-mentioned range, the water resistance of the resulting adhesive composition will be markedly reduced; If the addition ratio of the vinyl solution-type polymer (a-2) is smaller than the above-mentioned range, the initial adhesive strength of the resulting composition will be significantly reduced. Also,
If the oligoacrylate content is smaller than the above range, there will be no effect on improving the compatibility between the vinyl acetate solution polymer and the polyamide resin, and if it is larger, the water resistance will drop significantly. Therefore, neither is preferable.

Typical fillers include calcium carbonate, talc, asbestos, zinc white, silica, titanium oxide, and inorganic fillers such as Bengara or silica sand. However, this does not preclude the use of conventional organic fillers as long as they suit the purpose of the present invention. To the thus obtained composition of the present invention, various known and commonly used additives such as solvents, plasticizers, colorants, and curing accelerators for epoxy resins can be added, depending on the purpose.
