  • Patent number: 11333977
    Abstract: A curable composition includes a salt compound having a) an organic anion in which, in Hansen solubility parameter, ?d is 16 or more, ?p is 16 or more and 32 or less, and ?H is 60% or less of ?p and b) a counter cation. A lithographic printing plate precursor having an image-recording layer containing the curable composition, a method for producing a lithographic printing plate using the lithographic printing plate precursor, and a compound that is used in the image-recording layer in the lithographic printing plate precursor are also set out.
