DEFINITION

Classification: 430/583

Containing odd number of methine groups:

(under subclass 581) Subject matter in which the intercyclic acyclic methine chain linking the heterocyclic groups of the cyanine compound contains an add number of methine groups.

(1) Note. In view of the scope of indented subclasses 584 (five or more methines) and 585 (three methines), this subclass takes only those compositions in which the cyanine compound has a single methine in the intercyclic acyclic

methine chain or broadly disclosed odd numbered chains not falling in any indented subclass.
