Abstract
The present invention provides a lithographic printing plate precursor including at least a heat-sensitive layer and an ink repellent layer disposed on a substrate, the rate of gas generation therefrom being 6.5×105 g/m3 to 12.5×105 g/m3 as determined by GC-MS analysis in which the lithographic printing plate precursor is heated in a nitrogen stream at 450° C. for 5 minutes, and also provides a method for producing a lithographic printing plate and a method for producing printed matter therefrom.
Claims19
A lithographic printing plate precursor comprising at least a heat-sensitive layer and an ink repellent layer disposed on a substrate, the heat-sensitive layer containing a near-infrared absorbing compound having a maximum absorption wavelength in the wavelength range of 700 to 1,200 nm and an easily heat-decomposable compound being heat-decomposable at 450° C. or less and not having a maximum absorption wavelength in the wavelength range of 700 to 1,200 nm.
A lithographic printing plate precursor comprising at least a heat-sensitive layer and an ink repellent layer disposed on a substrate, the rate of gas generation from 1 m3 of the heat-sensitive layer being 6.5×105 g/m3 to 12.5×105 g/m3 as determined by GC-MS analysis in which the lithographic printing plate precursor is heated in a nitrogen stream at 450° C. for 5 minutes.
