Title:
OPTICALLY TRANSPARENT PRESSURE-SENSITIVE ADHESIVE SHEET, LAMINATE, PROCESS FOR PRODUCING LAMINATE, AND DISPLAY DEVICE WITH TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2017/057245
Kind Code:
A1
Abstract:
The present invention provides an optically transparent pressure-sensitive adhesive sheet using a heat-curable polyurethane composition, the adhesive sheet, after application to an adherend, e.g., a glass sheet, being capable of being inhibited from forming bubbles even in high-temperature ordinary-humidity environments and of retaining the stable application interface over long. The optically transparent pressure-sensitive adhesive sheet according to the present invention is constituted of a cured object obtained from a heat-curable polyurethane composition. The heat-curable polyurethane composition comprises a polyol component and a polyisocyanate component, wherein the polyol component has an olefin skeleton and the polyisocyanate component comprises an aliphatic polyisocyanate and/or an alicyclic polyisocyanate.
