Optically clear adhesive sheet, method for manufacturing optically clear adhesive sheet, laminate, display device with touch panel, and method for bonding optically clear adhesive sheet

Abstract

The present invention provides an optically clear adhesive sheet capable of reducing peeling after bonding due to causes such as outgassing and having excellent environment resistance, using a polyurethane that has excellent flexibility and is capable of giving a thick film. The optically clear adhesive sheet contains a polyurethane, the polyurethane being a cured product of a polyurethane composition containing a polyol component and a polyisocyanate component, the polyisocyanate component including a hydrophilic polyisocyanate, the optically clear adhesive sheet having a moisture content of 400 ppm or lower as measured by a Karl Fischer method.
