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.
Claims5
A pressure-sensitive adhesive sheet comprising:
- a substrate and a pressure-sensitive adhesive layer in order toward one side in a thickness direction, wherein
- the substrate contains
- a first 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;
- and
- in the first β-1,3-glucan derivative, the acyl group is represented by R1CO-, and the R1 is a hydrocarbon group having 1 or more and 5 or less carbon atoms.
