A photosensitive material having a photosensitive layer provided on a support which photosensitive layer comprises a compound represented by the formula [i]:
wherein [COUP] represent a 4-equivatent coupler from which a hydrogen is removed at a coupling position thereof,
B is a hydroxy group or
wherein R6 and R7 are individually and alkyl group or they may form a 1-piperidino, 1-piperazino, 1-pyrolidino or 4-morpholino group together with each other,
R1 is an alkyl, aryl, alkylamino or arylamino group, and
R2, R3, R4 and R5 individually are a hydrogen or halogen atom or aliphatic or aromatic group, or R2 and R3 may be fused to form a naphthalene ring.
The invention also relates to a presensitized printing plate as such material and to leuco-dyes contained therein.
