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.

A negative type image recording material comprising (A) an onium salt compound having sulfonic acid as the counter ion and selected from the group consisting of diazonium sulfonate represented by the following structural formula (III), (B) a cross-linking agent cross-linkable by an acid, (C) a polymer compound having an alkaline-soluble group, and (D) an infrared ray absorbing agent:
- Ar.sup.1 --N.sub.2.sup.+ R.sup.1 --SO.sub.3.sup.- (III)
- wherein R.sup.1 represents a hydrocarbon group having 20 or fewer carbon atoms which may be substituted;
- and Ar.sup.1 represents an aryl group having 20 or fewer carbon atoms which may be substituted.
