A yellow dye-forming coupler represented by formula (I):  wherein Q represents a group of nonmetallic atoms that form a 5- to 7-membered ring in combination with the &#x2014;N&#x2550;C&#x2014;N(R)&#x2014;; Rand Reach represent a substituent; Rrepresents an alkyl group; m represents an integer of 0 to 4; and X represents a hydrogen atom, or a group capable of being split-off upon a coupling reaction with an oxidized product of a developing agent; and when Rrepresents a primary alkyl group, Rrepresents &#x2014;(CH)O&#x2014;Rin which Ris an alkyl group having 4 to 8 carbon atoms. A silver halide color photographic light-sensitive material having at least one yellow dye-forming coupler represented by formula (I) in at least one layer provided on a support.

Dye-forming coupler, silver halide photographic light-sensitive material and azomethine dye compound

A compound represented by the formula (I) &lsqb;A represents a 5- to 7-membered hydrocarbon ring group; L represents &mdash;NR &mdash;CO&mdash;, &mdash;CO&mdash;NR &mdash; and the like (R represents a hydrogen atom, a lower alkyl group, a lower acyl group and the like); M represents an alkylene linking group (a carbon atom constituting the carbon chain may be replaced with a nitrogen atom, an oxygen atom and the like); X represents &mdash;S&mdash;, &mdash;O&mdash;, &mdash;NR &mdash;, &mdash;NR &mdash;CO&mdash; and the like (R and R represent a hydrogen atom, a lower alkyl group and the like) or a single bond; Y represents an alkyl group, an aryl group, an amino group, an aromatic heterocyclic group and the like; R represents a lower alkyl group, a lower alkenyl group, a lower alkynyl group or a lower acyl group; and R , R and R represent a hydrogen atom, a hydroxyl group, a lower alkyl group and the like&rsqb; or a salt thereof. The compound is useful as an active ingredient of medicaments for diseases in which neuropeptide Y is involved, ingestion control for hyperphagia and the like.
