Abstract
1334752 Photo-sensitive materials EASTMAN KODAK CO 19 April 1971 [2 March 1970] 22821/71 Heading G2C A light-sensitive composition comprises a lightsensitive halocarbon and a 4H-pyran derivative having a 4H-pyran ring which may be fused to a mono- or bi-cyclic aromatic nucleus and having an aryl substituent on the 4H-pyran ring, the composition producing a coloured image on imagewise exposure. The composition may be dispersed in a binder such as polyvinyl butyrol or styrene/ butyl methacrylate copolymer coated on a support, imagewise exposed to produce a coloured image which may be stabilized by heating to remove unreacted halocarbon. The composition may contain sensitizers such as dialkylaminocoumarino, -stilbazoles and -benzaldehydes; preexposure stabilizers such as benzimidazoles, azoles and azines; and image stabilizers such as thiazines or alkoxyborines. Preferred 4H-pyran derivatives are those of formula: wherein R and R<SP>1</SP> are H, alkyl or aryl and at least one of R and R' being aryl and R<SP>2</SP> and R<SP>3</SP> are either H or together complete a naphtho-pyran ring.
