Abstract
NEW MATERIAL:A pyrrylium salt shown by the formula I (R1 is H or methyl; R2 is H or methoxy; R31 and R32 are H, 1W5C alkyl, or alkoxy; X is O or S; Y- is ClO4 - or BF4 -).
EXAMPLE: 2,6-Di( 3'-methoxyphenyl )-4-( 3',4'-dimethoxyphenyl )pyrrylium perchlorate.
USE: A sensitizer for printing material and image recording material. Exhibiting improved sensitizing effects on a photosensitive resin of the cinnamylideneacetic acid type, and sensitive to visible light in high sensitivity.
PROCESS: For example, a banzaldehyde shown by the formula II and an acetophenone shown by the formula III (R30 is H, 1W5C alkyl, or alkoxy) in a molar ratio 1:2 are subjected to ring closure through dehydration in the presence of an acidic condensation agent and then undergo anion replacement with a HY (Y is Cl4 or BF4), to give a compound shown by the formula I where X is O.
