Lithographic printing plate precursor, method for producing lithographic printing plate, and color-developing composition

A lithographic printing plate precursor comprising:

• an image-recording layer on a support,
• wherein the image-recording layer includes a dye compound having a decomposable group that is decomposed by an acid, heat, or both and a structure in which decomposition of the decomposable group opens a ring or desorbs a leaving group and an electron-donating polymerization initiator,
• the decomposable group is different from the leaving group,
• the decomposable group is different from the ring, and
• the decomposable group is a group represented by any of Formula D-1 to Formula D-5,
• in Formula D-1 to Formula D-5, RD1 represents an alkyl group, RD2 represents an alkyl group or an aryl group, RD3 represents an alkyl group, RD4 represents a hydrogen atom or an alkyl group, RD5 represents an alkyl group, RD4 and RD5 may bond to each other to form a ring, RD6′s each independently represent an alkyl group or an aryl group, and RD7 represents an alkyl group or an aryl group.
