Abstract
A hard-coating, heat-absorbing composition which is capable of absorbing near-infrared rays from sunlight and a heat-shielding substance is disclosed. The composition comprises a silicone varnish for hard-coating comprising polysiloxane and, dissolved therein, diphenylthiourea and copper monobutyl-o-phthalate. It can be applied to plastic substrate and heated to cure the silicone varnish, whereupon curing of polysiloxane and production of a heat-absorbing compound are simultaneously effected. The composition ensures to provide various substrates with a heat-shielding characteristic.
