|1. (WO2018079853) PRESSURE-SENSITIVE ADHESIVE LAYER, ADHESIVE TAPE USING SAME, AND STRUCTURE|
|Applicants:||SEKISUI CHEMICAL CO., LTD.
|Title:||PRESSURE-SENSITIVE ADHESIVE LAYER, ADHESIVE TAPE USING SAME, AND STRUCTURE|
The pressure-sensitive adhesive layer according to the present invention contains 100 parts by mass of a (meth)acrylate ester-type polymer (A) and 1.0 to 60 parts by mass of a nonhalogenated phosphate ester flame retardant (B), wherein the tensile storage modulus at 23°C is 5 × 104 to 7 × 107 Pa, the temperature at which the tensile storage modulus becomes 1 × 104 Pa is not more than 205°C, and the amount of residual monomers is not more than 0.5 mass%. The present invention provides a pressure-sensitive adhesive layer having good adhesive strength and excellent flame retardancy.
