IMAGEABLE ELEMENTS AND METHODS OF USE IN NEGATIVE WORKING LITHOGRAPHIC PRINTING PLATES |
摘要 |
<p>Negative-working imageable elements that can be imaged using infrared radiation comprise an imageable layer and a protective overcoat on a hydrophilic substrate. The imageable layer includes an IR-sensitive cyanine dye. The protective overcoat predominantly comprises one or more poly(vinyl alcohol) resins, each of which has a hydrolysis level of 85% or less. The use of this particular overcoat composition used in combination with the IR-sensitive cyanine dye provides improved tolerance to fogging by white light while maintaining desired imaging speed.</p> |
