摘要：
The present invention relates to photography and, more particularly, to a novel spectrally (optically) sensitized radiation recording photographic element which comprises a cyanine dye of the formula:
WHEREIN L represents a methine group; m represents a positive integer of from 1 to 3, inclusive; Z and Z1 each represents the nonmetallic atoms necessary to complete a cyanine dye heterocyclic ring system containing a five or six membered heterocyclic nucleus; R and R1 each represents a divalent acylic cyclic group; X represents a quaternary ammonium, sulfonium or phosphonium group; Y represents a -SO3 or a -COO group; and W represents an anion.
