摘要

An aircraft window (2,3) of synthetic resin having hard coated film and at least a double-pane construction with a hollow interspace (25) therebetween for an aircraft cabin window (3) or a single pane construction including a mono-layer or multi-layer pane for an aircraft cockpit, canopy, or windshield window (2) comprises an outer synthetic resin molded body having hard coated film (24) on the outside surface of the aircraft and an inner synthetic resin molded body facing each other to form at least a double-pane construction with a hollow interspace (25) therebetween, or an synthetic resin molded body having hard coated film (32) on the outside surface or both of outside and inside of the aircraft to form a single pane construction of mono-layer or multi-layer, the hard coated film (24,32) comprising siloxane bonds and /or silazane bonds obtained by coating a coating composition containing perhydropolysilazane or its condensation polymer which is substantially soluble in organic solvent on the surface of the synthetic resin molded body and heat-treating the body at approximately ambient temperature to 100 DEG C in air or humidified air.
