Abstract
NEW MATERIAL:A pentamethine thiopyrylium salt of formula I (Z is anion; X is halogen, alkyl, or aryl).
EXAMPLE: 2, 6-Di-t-butyl-4-[ 3-benzyl-5-( 2, 6-di-t-butyl-4H-thiopyran-4-ylidene )- penta-1,3-dienyl]-thiopyrylium perchlorate.
USE: A photosensitizing agent which absorbs radiations of far- to near-infrared region. Since the agent does not absorb visible light, it is colorless and transparent. The agent is effective to impart an inorganic or organic photoconductive substance with high photosensitivity.
PROCESS: The compound of formula I is prepared by reacting e.g. the compound of formula II with a compound of formula III or its salt, or with a compound of formula IV (R is alkyl), e.g. in a carboxylic acid anhydride in the presence of an amine.
