摘要： 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.

摘要： The present invention relates to an adhesive film including a photothermal conversion layer including a light absorber and a thermally decomposable resin; and an adhesive layer, in which the thermally decomposable resin has a —COOH or —OH functional group and includes two kinds of acrylic resins having different weight average molecular weights, and an adhesive substrate including the adhesive film and a substrate to be processed. In the adhesive film and the adhesive substrate according to the present invention, it is possible to simplify a processing process of the substrate and reduce costs and time, and prevent damage to a substrate and a circuit or an element formed on the substrate.
