Abstract

1316398 Coated sheet materials NATIONAL CASH REGISTER CO 5 Oct 1971 [12 Oct 1970] 46221/71 Heading B2F [Also in Division G2] Coated materials for laser recording comprise a support which does not deform or change colour or transparency during recording coated with a layer not more than 5 microns thick and containing carbon black particles uniformly dispersed in a nitrocellulose binder. The preferred support is glass and the layer may contain between 20 and 90% by weight of carbon black and may contain a plasticiser such as dibutyl phthalate.
