Transparent laminates. |
摘要 |
<p>Novel laminates comprise transparent polymers with a high content of hydroxyl groups as core layer and adhesive layers applied to one or both sides which are tack-free under normal conditions and which can accept an outer layer, thermoplastic polyurethane-polyureas having a substantially linear molecular structure with exclusively aliphatically or cycloaliphatically bonded urethane segments and urea segments and a content of urea groups -NH-CO-NH- of 1 to 20% by weight and a content of carboxyl groups -COOH bonded directly to the main chain of the molecule in lateral positions, of 0.001 to 10% by weight, being used as adhesive layers.</p> |
