LAMINATE OF NEGATIVE TONE LITHOGRAPHIC PRINTING PLATE PRECURSOR AND METHOD OF PREPARING NEGATIVE TONE LITHOGRAPHIC PRINTING PLATE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18339622 titled 'LAMINATE OF NEGATIVE TONE LITHOGRAPHIC PRINTING PLATE PRECURSOR AND METHOD OF PREPARING NEGATIVE TONE LITHOGRAPHIC PRINTING PLATE
Simplified Explanation
- The present invention is a laminate of negative tone lithographic printing plate precursors. - Each precursor has at least one layer containing an infrared absorber with a HOMO of -5.43 eV or less. - The precursors are placed on a hydrophilic support. - The outermost layer surface on either side of the infrared absorber layer has an arithmetic mean height (Sa) between 0.3 μm and 20 μm. - The invention also includes a method of preparing a negative tone lithographic printing plate.
Original Abstract Submitted
The present invention provides a laminate of negative tone lithographic printing plate precursors each having at least one layer containing an infrared absorber with a HOMO of −5.43 eV or less on a hydrophilic support, in which in each of the negative tone lithographic printing plate precursors, at least one of an outermost layer surface on a side of the at least one layer containing an infrared absorber with reference to the support or an outermost layer surface on a side opposite to the side of the at least one layer containing an infrared absorber has an arithmetic mean height Sa of 0.3 μm or more and 20 μm or less. The present invention also provides a method of preparing a negative tone lithographic printing plate.
