ABSTRACT:
Laminated polarizers are described comprising a polarizing core layer and adhesive layers on one or both sides, each of which can accept a transparent outer layer, the polarizer being a polymer product containing polyacetylene, whose matrix is a polymer having polar groups, and as adhesive layers, in addition to conventional adhesives, such as epoxy resins or acrylic polymers, thermoplastic polyurethane-polyureas are used in particular, having a predominantly linear molecular structure with urethane segments and urea segments bonded exclusively aliphatically or cycloaliphatically.
