| titleOfInvention | Alteration of image tone in black and white photographic materials |
| abstract | Blue-black color favored in medical imaging is imparted to black and white photographic emulsions by the addition of a compound of formula I or II: pendently represent one or more carbon atoms necessary to complete a 5, 6 or 7 membered ring; R3 and R4 independently represent H, alkyl or aryl groups or together represent the atoms selected from C, N, O and S necessary to complete a 5, 6 or 7 membered cyclic ring but are not both H; R5 and R6 independently represent H or alkyl or together represent the atoms selected from C, N, O and S necessary to complete a 5, 6 or 7 membered ring; X represents a bond or a divalent linking group, each Y may be the same or different and is selected from S, Se, O, and NR7, where R7 is H or alkyl of up to 5 carbon atoms, and Z is S or Se. |
