Abstract: PROBLEM TO BE SOLVED: To provide a resin composition for an adhesive, which has adhesivity to various types of plastic films, adhesivity to metals such as copper, aluminum and stainless steel, and adhesivity to glass epoxides, and can maintain the adhesive force in high temperatures and high humidities, and can secure the sheet life of a B-stage adhesive sheet adaptable to the commercial distribution at ordinary temperature. SOLUTION: The resin composition for an adhesive comprises (a) a polyurethane resin containing a carboxyl group and having an acid value (unit: equivalent weight/10 6 g) of ≥100 and ≤1,000, a number-average molecular weight of ≥5.0×10 3 and ≤1.0×10 5 and a glass transition temperature of ≥-10°C and ≤70°C, (b) an epoxy resin containing a nitrogen atom, and (c) an epoxy resin having a dicyclopentadiene skeleton, wherein the formulation ratio of the resin (b) is ≥0.1 mass% and ≤20 mass% to the total of the epoxy resins contained in the resin composition. Also provided are an adhesive, an adhesive sheet, a laminate for a wiring board, and a printed wiring board, containing the composition. COPYRIGHT: (C)2010,JPO&INPIT
