STACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18582657 titled 'STACK
The patent application describes a stack consisting of a lithographic printing plate precursor with an image-recording layer containing an infrared absorber, a polymerizable compound, and a polymerization initiator, along with an interleaving paper.
- The interleaving paper has an air permeation resistance of 55 seconds or more.
- The interleaving paper is overlapped with the lithographic printing plate precursor, ensuring contact with the image-recording layer.
- The color difference (ΔE) of the image-recording layer before and after storage in specific conditions is less than 3.0.
Potential Applications: - This technology can be used in the printing industry for lithographic printing plate production. - It can improve the quality and longevity of printed materials by reducing color differences.
Problems Solved: - Prevents color changes in the image-recording layer during storage. - Ensures proper air permeation resistance to protect the lithographic printing plate precursor.
Benefits: - Enhanced print quality and consistency. - Increased durability and longevity of printed materials.
Commercial Applications: Title: Enhanced Lithographic Printing Plate Production for Improved Print Quality This technology can be utilized by printing companies to produce high-quality lithographic printing plates, leading to better print results and customer satisfaction. The market implications include improved competitiveness and customer retention.
Questions about the technology: 1. How does the air permeation resistance of the interleaving paper impact the quality of the lithographic printing plate precursor?
- The air permeation resistance helps maintain the stability of the image-recording layer, preventing color changes and ensuring consistent print quality.
2. What are the specific storage conditions that affect the color difference of the image-recording layer?
- The color difference is influenced by temperature and humidity levels during storage, with specific thresholds to maintain quality.
Original Abstract Submitted
A stack including: a lithographic printing plate precursor including an image-recording layer which contains an infrared absorber, a polymerizable compound, and a polymerization initiator; and an interleaving paper stacked on the lithographic printing plate precursor, in which air permeation resistance of the interleaving paper is 55 seconds or more, or a stack including: a lithographic printing plate precursor including an image-recording layer which contains an infrared absorber, a polymerizable compound, and a polymerization initiator; and an interleaving paper stacked on the lithographic printing plate precursor, in which the interleaving paper is overlapped with the lithographic printing plate precursor to be in contact with a surface of the lithographic printing plate precursor on an image-recording layer side, and a color difference ΔE of the image-recording layer before and after storage in a dark room in an environment of 25° C. and 55% RH for 3 days is less than 3.0.
