Provided is an adhesive composition for an electrochemical device capable of forming an adhesive layer that has excellent adhesiveness in electrolysis solution and can improve electrical characteristics of an electrochemical device. The adhesive composition can be used for adhering an electrode assembly and a casing to one another. The adhesive composition contains organic particles having a core-shell structure including a core portion and a shell portion that partially covers an outer surface of the core portion. A polymer of the core portion has a degree of swelling in electrolysis solution of at least a factor of 5 and no greater than a factor of 30, whereas a polymer of the shell portion has a degree of swelling in electrolysis solution of greater than a factor of 1 and no greater than a factor of 4.

The present invention is an adhesive composition for stabilizing an electrical conductor. The adhesive composition includes a base polymer and an additive for absorbing UV light, such as a benzotriazole or a benzophenone. When the adhesive composition is in contact with the electrical conductor, the electrical conductor has less than about a 20% change in electrical resistance over a period of about 500 hours.

The present invention provides a low tack bubble free advertisement film, comprising an advertisement film layer, a dot glue layer and a release layer; a adhesion promoter layer is disposed between the back face of the advertisement film layer and the dot glue layer; the dot glue layer consists of over four independent, separable glue dots; and the area of the dot glue layer is 30-80% of the adhesion promoter layer. The present invention can provide a special advertisement film in the field of advertising consumables. The advertisement film has many advantages, such as low tack, totally bubble free, removable, and can be pasted for a long time. The present invention provides a convenient, efficient, feasible solution for advertising consumables.
