ABSTRACT:
An infrared imaging composition contains two essential components, namely an infrared radiation absorbing compound, and a phenolic resin that is either mixed or reacted with an o-diazonaphthoquinone derivative. These compositions are useful in photosensitive elements such as lithographic printing plates that can be used to provide images using laser imaging, followed by uniform exposure and development.
