PROBLEM TO BE SOLVED: To provide a tackifier capable of exhibiting sufficient transparency and excellent adhesiveness to various adherents, particularly glass, and an adhesive composition containing the tackifier, and additionally an adhesive product using the composition.SOLUTION: An adhesive composition comprising a specific low molecular weight acrylic polymer containing an amide group and/or amino group as a component as a tackifier is provided. The acrylic polymer contains a vinyl monomer having an amide group and/or amino group at a content ranging from more than 10 mass% to 90 mass% or less of total mass of the all components, a glass transition temperature (Tg) is 40-150°C, and a number average molecular weight is 500-10,000. |
