US 12,187,921 B2 · Powder adhesive and bonded article

Abstract

The powder adhesive comprises a thermoplastic resin and particles of an aromatic compound, wherein the particles of an aromatic compound are particles of a compound that has an aromatic ring and an azo bond bonded to the aromatic ring, or are particles of a compound comprising a heteroaromatic ring comprising nitrogen atom; the thermoplastic resin comprises an ester group; and, designating Es (mmol/g) as an ester group concentration in the thermoplastic resin, M (mass %) as a content of the aromatic compound particles in the powder adhesive, and N (mmol/g) as a nitrogen atom concentration in the aromatic compound particles, Es is from 1.0 mmol/g to 4.5 mmol/g, M is from 1.0×10−4 mass % to 1.0×100 mass %, and N is from 5.0 mmol/g to 15.0 mmol/g.
