Abstract
A negative type image recording material comprising (A) an onium salt compound having sulfonic acid as the counter ion to generate sulfonic acid decomposed by light or heat, (B) a cross-linking agent cross-linkable by an acid such as a phenol derivative preferably having at least two hydroxymethyl or alkoxymethyl groups bonded to a benzene ring, (C) a polymer compound having an alkaline-soluble group such as a novolak resin, and (D) an infrared ray absorbing agent which is a dye or pigment to absorb an infrared ray having a wavelength of 720 to 1,200 nm. The negative type image recording material can allow direct production of a form plate from digital data, and provide excellent storability, a good latitude of heat treatment conditions after exposure, and excellent plate wear upon printing.
