IPC: C07C311/29
Filed: 1989-07-20
Abstract: A color light-sensitive material comprising a 
support having provided thereon a light-sensitive silver 
halide, a binder, a reducible dye donating compound, and 
at least one reducing agent selected from the group 
consisting of a compound represented by formula (IA) and 
a compound represented by formula (IB): 
  
wherein R¹, R², R³, R⁴, R⁵, and R⁶, wihch may be the same 
or different, each represents a hydrogen atom, a halogen 
atom, a hydroxy group, a substituted or unsubstituted 
alkyl group, a substituted or unsubstituted aryl group, 
a substituted or unsubstituted acylamino group, a 
substituted or unsubstituted alkoxy group, a substituted 
or unsubstituted aryloxy group, a substituted or 
unsubstituted alkylthio group, a substituted or 
unsubstituted arylthio group, a substituted or 
unsubstituted acryl group, a substituted or unsubstituted 
sulfonyl group, a substituted or unsubstituted carbamoyl 
group, or a substituted or unsubstituted sulfamoyl 
 
 
group, provided that at least one of R¹ and R³ and at 
least one of R⁴ and R⁶ represent a hydroxyl group; or 
any adjacent two of R¹, R², R³, R⁴, R⁵, and R⁶ are 
connected to each other to form a carbocyclic ring; X 
represents a divalent linking group; and ℓ represents 0 
or 1; 
  
wherein R¹¹ and R¹², wihch may be the same or different, 
each represents a hydrogen atom, a halogen atom, a 
substituted or unsubstituted alkyl group, a substituted 
or unsubstituted aryl group, a substituted or 
unsubstituted acylamino group, a substituted or 
unsubstituted alkoxy group, a substituted or 
unsubstituted aryloxy group, a substituted or unsub­
stituted alkylthio group, a substituted or unsubstituted 
arylthio group, a substituted or unsubstituted acyl 
group, a substituted or unsubstituted sulfonyl group, a 
substituted or unsubstituted carbamoyl group, or a 
substituted or unsubstituted sulfamoyl group, or R¹¹ and 
R¹² are taken together to form a carbocyclic ring; R¹³ 
 
 
represents an unsubstituted or alkyl-substituted alkyl­
ene group; R¹⁴, R¹⁵, R¹⁶, R¹⁷, and R¹⁸, wihch may be the 
same or different, each represents a hydrogen atom, a 
halogen atom, a cyano group, a nitro group, a 
substituted or unsubstituted alkyl group, a substituted 
or unsubstituted acylamino group, a substituted or 
unsubstituted sulfonamido group, a substituted or 
unsubstituted alkoxy group, a substituted or unsub­
stituted aryloxy group, a substituted or unsubstituted 
alkylthio group, a substituted or unsubstituted arylthio 
group, a substituted or unsubstituted amino group, a 
substituted or unsubstituted acyl group, a substituted 
or unsubstituted acyloxy group, a substituted or 
unsubstituted carbamoyl group, a substituted or unsub­
stituted carbamoylamino group, a substituted or unsub­
stituted sulfamoyl group, a substituted or unsubstituted 
sulfamoylamino group, a substituted or unsubstituted 
alkoxycarbonyl group, a substituted or unsubstituted 
aryloxycarbonyl group, a substituted or unsubstituted 
heterocyclic group, a substituted or unsubstituted 
alkoxysulfonyl group, or a substituted or unsubstituted 
aryloxysulfonyl group; R¹⁴, R¹⁵, and R¹⁶ each may 
further represent a hydroxyl group; or any adjacent two 
of R¹⁴, R¹⁵, R¹⁶, R¹⁷, and R¹⁸ are connected to each other 
to form a carbocyclic or heterocyclic ring; X 
 
 
represents -CO- or -SO₂-; m and n each represents 0 or 
1; and the total number of carbon atoms in R¹¹, R¹², 
R¹³, R¹⁴, R¹⁵, R¹⁶, R¹⁷, and R¹⁸ is 8 or more.
