<p>PURPOSE:To obtain safety glass made of a synthetic resin having high adhesiveness, excellent impact resistance and durability by improving not only the adhesiveness of a polycarbonate resin plate and an intermediate bonding layer but also the intermediate bonding layer and other impact-resistant acrylic resin plate. CONSTITUTION:Safety glass made of a synthetic resin is constituted by bonding a polycarbonate resin plate A and an impact-resistant acrylic resin plate C through a thermoplastic polyurethane intermediate bonding layer B composed of a reaction product of nonyellowing diisocyanate, polyether diol and a curing agent and prepared by pressing the laminate of the polycarbonate resin plate A, the thermoplastic polyurethane intermediate bonding layer B and the impact- resistant acrlic resin plate C at 100-150 deg.C under pressure of 5-50kg/cm<2> by a hot press.</p> |
