Abstract: An adhesive composition contains a β-1,3-glucan derivative having a degree of substitution of the acyl group of 2.6 or more and less than 3.0, and an isocyanate-based crosslinking agent. A pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer formed from the adhesive composition.

Abstract: A film contains a β-1,3-glucan derivative obtained by introducing an acyl group into a β-1,3-glucan and at least one resin selected from the group consisting of a rosin-based resin, a terpene-based resin, and a petroleum-based resin. The acyl group is represented by RCO—, and the R is a hydrocarbon group having 1 or more and 5 or less carbon atoms. Parts by weight of the resin with respect to 100 parts by weight of the β-1,3-glucan derivative are 90 parts by weight or less. A pressure-sensitive adhesive tape includes the film and a pressure-sensitive adhesive layer.
