A tackifier having sufficient transparency and moisture and heat whitening resistance and capable of exhibiting excellent adhesion to various adherends, particularly glass, and a pressure-sensitive adhesive composition containing the same, and further A pressure-sensitive adhesive product is provided. A pressure-sensitive adhesive composition comprising a specific low molecular weight acrylic polymer having a hydroxyl group as a constituent component as a tackifier. The acrylic polymer contains a vinyl monomer having a hydroxyl group in a range of 10 to 70% by mass in all the structural units, a glass transition temperature (Tg) of 40 to 150 ° C., and a number average molecular weight. Is 500 to 10,000. [Selection figure] None |
