摘要： Infrared radiation-sensitive compounds have been found that are represented by Structure DYE as follows: wherein R is a substituted or unsubstituted alkyl group, substituted or unsubstituted cycloalkyl group, substituted or unsubstituted heterocyclic group, or substituted or unsubstituted carbocyclic aromatic group, R1 and R1 are independently substituted or unsubstituted heterocyclic or carbocyclic aromatic groups, and M+ is a monovalent cation. These compounds have a &lgr;max above 700 nm and are can be used in a number of photosensitive or heat-sensitive imaging materials.
