ABSTRACT:
Novel squaraine dyes and compositions of matter containing such dyes are disclosed. The novel 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.
