    摘要: A precursor for electronic parts, for example printed circuit boards, has a negative-working thermally-imagable layer on a substrate, for example a copper board or semiconductor. The layer comprises a cross-linking agent, a thermally-activated acid generator, and a polymeric substance containing polyvinylphenol units and alkyl acrylate units. Such as layer has improved mechanical properties with maintenance of good imaging properties.
