Abstract

An objective is to provide an image recording material exhibiting an excellent exposure visualization property as well as an image formation process employing the image recording material, and further to provide not only a printing plate material exhibiting excellent on-press developability and printing durability, but also an image formation process employing the printing plate material, accompanied with an excellent exposure visualization property. Also disclosed is an image recording material possessing a support and provided thereon, a thermosensitive image formation layer, wherein the thermosensitive image formation layer contains thermoplastic spherical particles having an average particle diameter of 100 - 500 nm, and exhibits a structural color originated with the thermoplastic spherical particles.

Description

Technical field [0001] The present invention relates to an image recording material and an image forming method using the image recording material, and more particularly to a computer-to-plate (computer-to-plate) (hereinafter referred to as CTP) method The thermal printing plate material used and the image forming method using the material. Background technique [0002] At present, in the printing field, with the digitization of printed image data, it is gradually possible to print by CTP, but in this printing, it is required to be cheap, easy to operate, and have the same printing adaptability as the current so-called PS plate. Ways to use printed materials. [0003] Especially in recent years, there is a demand for printing plate materials that can be suitably used in current printing presses without the need for developing processing liquids containing special agents (such as alkalis, acids, solvents, etc.). For example, there are known, Phase change type printing plate materi...
