摘要：
An adhesive for bonding polyethylene terephthalate, polycarbonate and other transparent thermoplastic sheets to form optically clear laminants with improved bond strengths which remain intact over temperature exposures ranging from -40.degree. C. to 70.degree. C. and humidities ranging up to 90% at 40.degree. C. is provided. The adhesive is a combination of approximately 20% molecular weight phenoxy resin and approximately 80% molecular weight polyurethane resin.
