摘要： In accordance with the present invention, there are provided methods to substantially increase the effective exposure sensitivity of photopolymerizable materials without chemical modification thereof. This is accomplished by subjecting such materials to a relatively low energy pre-exposure prior to subjecting such materials to the main imaging exposure. Increase in the effective exposure sensitivity of photopolymerizable materials provides improved image quality in the exposed matrix and allows increased exposure speeds to be employed. In accordance with another aspect of the present invention, there are provided imaging apparatus useful for carrying out the above-described process. Invention apparatus enable one to increase the effective exposure sensitivity of photopolymerizable materials.

摘要： In accordance with the present invention, there are provided water-developable photopolymerisable compositions useful for the preparation of printing plates. Printing plates prepared employing invention compositions have excellent form stability, thereby enabling such plates to be handled without the need for excessive care. Once photopolymerized, printing plates of the invention have excellent physical properties, enabling their use in many very demanding commercial applications, e.g., commercial flexographic printing. Such applications require the photopolymerized resin to have excellent water resistance (so that exposure to water-based inks does not significantly alter resin properties), as well as high durability (so that the physical contacting associated with the printing process does not significantly degrade resin properties).
摘要翻译：根据本发明，提供了可用于制备印刷版的水可显影的可光聚合组合物。使用本发明组合物制备的印刷版具有优异的形状稳定性，从而能够在不需要过度注意的情况下处理这样的板。一旦光聚合，本发明的印版具有优异的物理性能，使其能够用于许多非常苛刻的商业应用中，例如商业柔版印刷。这样的应用需要光聚合树脂具有优异的耐水性（使得暴露于水性油墨不会显着改变树脂性能）以及高耐久性（使得与印刷方法相关的物理接触不会显着降低树脂性能）。

摘要： In accordance with the present invention, there are provided rapid, efficient methods for drying solvent-containing resin compositions, and apparatus useful therefor. Invention methods can be used for removing solvent from a variety of resins, such as, for example, printing plates. Printing plates processed employing invention methods and apparatus are ready for use in printing applications in a relatively short period of time, especially compared to the time required for conventional convection drying. Moreover, printing plates processed according to the present invention method and apparatus are not subjected to excessive levels of heat, as is frequently the case with conventional convection drying. Excessive heating tends to be detrimental to the performance properties of the polymeric resin. In a particular aspect of the present invention, there are provided novel compositions which, upon dryin according to the methods described herein, undergo a color change, thereby indicating when the drying process is substantially complete. When used for the production of printing plates, invention compositions provide finished printing plates which display a readily observed contrast between the floor and image portions thereof.
摘要翻译：根据本发明，提供了用于干燥含溶剂的树脂组合物的快速，有效的方法及其有用的装置。本发明的方法可用于从各种树脂例如印刷版中除去溶剂。使用发明方法和装置处理的印刷版在相对短的时间内可以用于印刷应用，特别是与常规对流干燥所需的时间相比。此外，根据本发明的方法和装置处理的印版不会经受过多的热量，如常规对流干燥的情况。过度加热往往不利于聚合物树脂的性能。在本发明的特定方面，提供了新的组合物，其根据本文所述的方法在干燥后经历颜色变化，从而指示干燥过程何时基本完成。当用于生产印版时，本发明组合物提供成品印版，其在地板和其图像部分之间显示出容易观察到的对比度。

摘要： In accordance with the present invention, water-developable photopolymerizable compositions useful for the preparation of durable printing plates capable of providing very high levels of resolution have been developed. Printing plates prepared employing invention compositions, once photopolymerized, have excellent physical properties, enabling their use in many very demanding applications, e.g., commercial letterpress and newspaper printing. Such applications require the photopolymerized resin to provide a sharp image and good durability after curing. Photopolymerization of invention resin yields a product with excellent physical characteristics, acceptable by letterpress printing standards. In addition, photopolymerization of invention composition provides a product which demonstrates sufficient toughness to be used for extended printing runs as required in such areas as metal decorating, newspaper, plastic packaging, business forms, and the like.
