Abstract
Compounds of the class of organic salts based on monomethine cyanine cation and azomethine complex cation are useful to promote light sensitivity and light resistance in laser writable and readable recording material. The compounds of Formula (I) and (IV) are exemplified in Formula (I) with X being oxygen, sulfur, or selenium; Rand Rare each C1-C20 alkyl, C7-C30 arylalkyl; Rto Rare each hydrogen, C1-C20 alkyl, etc.; Rand Rmay be taken together to form a 6-membered ring; Yand Yare each C1-C20 alkyl; Rto Rare each hydrogen, C1-C20 alkyl, etc.; and adjacent two of Rto Rmay be taken together to form a 5- or 6-membered ring. In Formula (IV) M' is Fe, Co, Ni, Cr or Mn; and Rto Rare each hydrogen, nitro, —NRR′ (R and R′ are each C1-C4 alkyl).
