Abstract
A composition used as a resist in the manufacture of electronic parts, for example printed circuits, and which is rendered soluble in a developer by pattemwise delivery of heat, comprises a polymer and optionally an infrared absorbing compound. However in contrast to conventional compositions no compound is present which alters the solubility of the polymer in an aqueous developer.
