ABSTRACT:
Squaraine dyes and compositions of matter containing such dyes are disclosed. The squaraine dyes have an absorption maximum greater than 600 nanometers and are particularly useful in conjunction with a helium
eon (He/Ne) laser. Some of the squaraine dyes are hydrophilic and are therefore water soluble or water compatible and others of the squaraine dyes are lipophilic.
