Document Type and Number:
WIPO Patent Application WO/2022/209116
Kind Code:
A1
Abstract:
A thermoplastic resin composition for adhesion use, which is used for adhering two objects of the same type or different types to each other, the resin composition comprising a phenoxy resin and a thermoplastic elastomer and satisfying the following requirements: (a) the melting point measured by a differential scanning calorimetric (DSC) method is 180°C or higher; and (b) the stretch at break measured in accordance with JIS K 7161 is 10% or more. The phenoxy resin is preferably one having a glass transition temperature falling within the range from 65°C to 160°C and having a bisphenol backbone, and the thermoplastic elastomer is preferably a polyester elastomer having a stretch at break of 200% or more and a melting point higher than 180°C.
