Abstract

An infrared-sensitive color developing composition develops colors in a high density with an infrared exposure and does not significantly discolor when aged. A lithographic printing plate precursor which has extremely excellent plate-inspecting properties and favorable storage stability and is capable of maintaining favorable color-developing properties is provided, as is a plate making method for a lithographic printing plate in which the lithographic printing plate precursor is used. A new compound that can be preferably used as an infrared-sensitive color developer is also provided. An infrared-sensitive color developing composition of the invention includes a compound represented by Formula (1) (Component A). In addition, the compound in the present invention is represented by Formula (1).
