Title:
BRIDGED CYANINE COMPOUNDS AND OPTICAL RECORDING MATERIALS CONTAINING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/010433
Kind Code:
A1
Abstract:
Cyanine compounds represented by the general formula (I): (I) wherein R1
and R2 are each independently hydrogen, hydroxy, halogeno, nitro,
cyano, an organic group having 1 to 30 carbon atoms, or a group represented by the
general formula (II), (II') or (III); R3 and R4 are
each independently hydrogen, an organic group having 1 to 30 carbon atoms, or
a substituent represented by the general formula (III); R1 and R2 may
be united to form a ring structure; R3 and R4 may be united to
form a heterocycle; N-R3 together with the adjacent methylene group of
the polymethylene chain may form a heterocycle; X is oxygen, sulfur, selenium, -CR5R6-,
-NH- or –NYj-; R5 and R6 are each independently
an organic group having 1 to 30 carbon atoms or a substituent represented by the
general formula (II), (II') or (III), or alternatively R5 and
R6 may be united to form a ring structure; Yj is an organic
group having 1 to 30 carbon atoms or a group represented by the general formula
(III); Z0 is an organic group having 1 to 10 carbon atoms; n is 1 or 2; r
is 2 to 8; Anq- is a q-valent anion; q is 1 or 2; and p is a coefficient making
the charge neutral.
