Abstract
A heat-sensitive composition can be used to make a heat-sensitive imaging material. The composition includes a water-soluble or water-dispersible binder and dispersed therein, a photothermal conversion material, and hybrid particles of a combustible nitro-resin and an addition polymer derived from one or more ethylenically unsaturated polymerizable monomers. The hybrid particles preferably have a core-shell structure with the combustible nitro-resin comprising the core and the addition polymer providing the shell. These imaging materials are particularly useful as 'direct-write' thermally imageable elements useful to provide lithographic printing plates without ablation or the need for alkaline development.
