Abstract
A negative working non-ablative lithographic printing plate precursor is provided which includes a metal support such as an anodized aluminum plate and provided thereon a layer or a stack of layers, wherein at least one layer includes a near infrared light absorbing compound which is the main component of the layer(s). As the amount of other reactive compounds besides the near infrared light absorbing compound is less than 20% by weight, excellent-storage stability is obtained. In a highly preferred embodiment the layer or stack of layers is substantially free from the other reactive compounds. The material is very suitable for computer-to-plate and computer-to-press applications as it can be used as a printing master directly after exposure or may be processed by rinsing with plain water.
