An inkjet ink for preparing a lithographic printing plate contains a contrast dye including A, D, and B groups wherein A represents a phosphorous containing group capable of reacting with the surface of a lithographic receiver; D represents a chromophore group absorbing light between 400 nm and 700 nm; and B represents an aliphatic group of at least 6 carbon atoms. A lithographic printing plate includes such an inkjet ink and methods for direct plate making include jetting on a printing plate precursor.
