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: CH2=C(R)-X (I) 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.
