| titleOfInvention | Photochromic composition containing polyhalogenated compound,spiropyran compound and sensitizer 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 ON EXPOSURE WITH ULTRA-VIOLET LIGHT WITH THE SPIROPYRAN A DYE SALT AND AS SENSITIZING AGENT A COMPOUND SELECTED FROM THE GROUP COMPRISING: (A) ORGANIC COMPOUNDS CONTAINING TWO RADICALS OF DIFFERENT ELECTRON-AFFINITY INCLUDING GROUPS OR ATOMS OF DIFFERENT ELECTRON-AFFINITY LINKED TO EACH OTHER THROUGH A CONJUGATED SYSTEM, (B) ORGANIC COMPOUNDS CONTAINING AN AROMATIC NUCLEUS OR AROMATIC RING SYSTEM IN WHICH TWO ADJACENT CARBON ATOMS ARE COMMON TO SAID NUCLEUS OR RING SYSTEM AND TO AN ADJACENT RING WHICH HAS NO CONJUGATED CHARACTER AND WHICH AT ONE END IS LINKED TO THE AROMATIC NUCLEUS OR RING SYSTEM THROUGH A CARBON-CARBON BOND AND AT THE OTHER END IS LINKED TO SAID NUCLEUS OR RING SYSTEM THROUGH A SECONDARY OR TERTIARY AMINO GROUP, SAID ORGANIC COMPOUNDS INCLUDE THOSE HAVING A SAID NUCLEUS OR RING SYSTEM IN SUBSTITUTED FORM. PREFERRED RECORDING MATERIALS CONTAIN A SPIRODINAPHTHOPYRAN COMPOUND, CARBON TETRABROMIDE AND/OR IODOFORM AND AS SENSITIZING AGENT MICHLER''S KETONE OR A 2,2,4-TRIMETHYL-1,2-DIHYDROQUINOLINE IN POLYSTYRENE AS BINDING AGENT. |
