ABSTRACT:
Combustible core-shell particles have a nitro-resin core that is covered by an addition polymer shell in a weight ratio of from 20:1 to 0.2:1 (core:shell). The shell polymer is derived from one or more ethylenically unsaturated polymerizable monomers that are represented by the following Structure I:in-line-formulae description="In-line Formulae" end="lead"?CH2═C(R)-X  (I)in-line-formulae description="In-line Formulae" end="tail"?wherein R is hydrogen or methyl, and X is any monovalent moiety except a phenyl group. These combustible core-shell particles are particularly useful in thermal imaging materials such as “direct-write” printing plate precursors.
