| titleOfInvention |
Photographic recording and reproduction of information photochromic composition containing polyhalogenated hydrocarbon, spiropyran compound and heterocyclic mercapto compound and the use thereof |
| abstract |
A photographic process wherein a visible image is formed by print-out or optical development in a recording material comprising in intimate admixture a spiropyran compound, an ultra-violet light-sensitive compound capable of producing an exposure with ultra-violet light with the spiropyran a dye salt and as sensitizing agent an organic nitrogen containing compound having a thiol group or in its tautomeric form a thione group as represented in the following tautomeric structural parts : ¦¦¦¦ HS-C=N -><- S=C-NH Preferred recording materials contain a spirodinaphthopyran compound, carbon tetrabromide and/or iodoform and as sensitizing agent 2-mercaptobenzthiazole in conjunction with a triaryl stibine as antifogging agent. |
