る。2. Description of the Related Art Saturated polyester-based adhesives are generally composed mainly of a thermoplastic high-molecular weight linear polyester resin, and include polyester, polyvinyl chloride, polycarbonate, cellulose acetate, plastic materials such as ABS, and aluminum. It has excellent adhesion and coating properties to metal materials such as copper, steel, stainless steel, and various fiber materials such as polyester fiber. Since it is a thermoplastic polyester, it has the advantages that it can be bonded in a very short time and has excellent flexibility, but on the other hand, the expected adhesive strength can be obtained even when the above adhesive is actually applied to a polycarbonate substrate. There was a practical problem because it was not possible. Therefore, it has been proposed to cure the hydroxyl groups at both ends of the linear polyester (partially converted to carboxyl groups by thermal oxidation) with an appropriate curing agent to improve the adhesion reliability.

を目的とする。However, even in the above proposed technique, the adhesiveness to the polycarbonate substrate is basically insufficient, so that the expected crosslinking effect can hardly be expected. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a saturated polyester-based adhesive that adheres at a low temperature in a short time and has excellent adhesiveness to a polycarbonate substrate.

The four components of dimethyl terephthalic acid / isophthalic acid / neopentyl glycol / ethylene glycol are essential.
The linear polyester resin as the main component is used alone or as a blend of two or more. The molecular weight of the linear polyester resin is preferably 5,000 or more in terms of number average molecular weight (Mn). If it is less than that, the cohesive force of the adhesive itself is reduced, and a high adhesive force cannot be obtained. Polycarbonate is most suitable as the adherend, but it can also be used for plastic materials such as polyester, polyvinyl chloride, cellulose acetate, ABS, metal materials such as aluminum, copper, steel, stainless steel, and various fiber materials such as polyester fiber.
