| titleOfInvention |
Optically clear adhesive sheet, method for manufacturing optically clear adhesive sheet, laminate, and bonded structure |
| abstract |
The present invention provides an optically clear adhesive sheet preventing whitening and delay bubbles during storage in a high-humidity environment using a heat-cured polyurethane that has excellent flexibility and is capable of giving a thick film. The optically clear adhesive sheet contains a heat-cured polyurethane, the heat-cured polyurethane being a cured product of a thermosetting polyurethane composition containing a polyol component and a polyisocyanate component, the polyisocyanate component containing both a polyisocyanate having a hydrophilic unit and a polyisocyanate having no hydrophilic unit, the optically clear adhesive sheet showing a moisture absorption coefficient of 3600 ppm or lower after being subjected to a test in which the sheet is left in a high-temperature, high-humidity environment with a temperature of 85°C and a humidity of 85% for three hours. |
