If it is less than 5% by weight, the sealing properties of the adhesive composition against liquids and gases will be significantly reduced, and the cohesive force of the adhesive composition will be reduced, resulting in a decrease in adhesive strength, while if it exceeds 0% by weight, the meltability will be poor. As a result, it becomes difficult to obtain a uniform adhesive composition, and the melt viscosity of the adhesive composition increases, making it difficult to use it as an adhesive composition for hot melt seals.

j% by weight, or the total amount of the polyimbutylene and hydrocarbon tackifier is 20 to 53% by weight of SO, or the hydrocarbon tackifier is 20 to 53% by weight, thereby imparting adhesive strength to the adhesive composition. to lower the melt viscosity. Here, the molecular weight of polyisobutylene is /+21
Those having a diameter of OOO or less are suitably used as tackifiers that are viscous and have excellent transparency. This polyisobutylene also has some sealing properties against liquids and gases, so when using a large amount of tackifier (for example, 30% by weight or more based on the adhesive composition), use a hydrocarbon tackifier. It is preferable to use polyisobutylene as a tackifier. However, when the Staudinger viscosity average molecular weight of polyisobutylene exceeds 1200, it becomes rubbery and is unsuitable as a tackifier. On the other hand, as a hydrocarbon tackifier, an aliphatic hydrocarbon tackifier having 5 to 9 carbon atoms is used from the viewpoint of thermal stability and weather resistance.
