  QHB-Modified free radical polymerizable compounds and free radical polymerizable compositions that comprise these compounds are disclosed. A QBH-modified free radical polymerizable compound has at least one moiety that comprises at least one free radical polymerizable group; a supporting backbone, and at least one and preferably at least two moieties capable of forming four or more, typically four, hydrogen bonds with similar or complementary units on other molecules or portions of molecules. Free radical polymerizable compositions that contain these compounds may be used in any of the well-knows applications for free radical polymerizable compositions. They are especially useful for the formation of imageable elements useful as lithographic printing plate precursors.

  Improved photopolymerization initiator systems are comprised of a spectral sensitizer that sensitizes in the ultraviolet or visible regions of the spectrum and an N-aryl, O-aryl or S-aryl polycarboxylic acid co-initiator. The improved initiator systems are incorporated in photo-polymerizable compositions containing one or more addition-polymerizable ethylenically-unsaturated compounds to form compositions suitable for the preparation of radiation-sensitive layers in lithographic printing plates adapted to be imagewise-exposed with ultraviolet- or visible-light-emitting lasers such as argon-ion lasers and frequency doubled Nd:YAG lasers. Such plates are able to effectively meet the dual requirements of very high photospeed and very good shelf-life required in computer-to-plate systems.

  改进的光聚合引发剂体系由在光谱的紫外线或可见光区域敏化的光谱敏化剂和 N-芳基、O-芳基或 S-芳基聚羧酸共引发剂组成。改进后的引发剂体系与含有一种或多种可加成聚合的乙烯基不饱和化合物的光聚合组合物结合，形成的组合物适用于制备平版印刷板中的辐射敏感层，该板可使用紫外线或可见光发射激光器（如氩离子激光器和倍频 Nd:YAG 激光器）进行图像曝光。这种印版能够有效地满足计算机直接制版系统对极高的光速和极好的保存期限的双重要求。

  A peel-developable lithographic printing plate is comprised of a substrate, a hydrophilic layer comprising a polymeric acid overlying the substrate, a radiation-sensitive image-forming layer overlying the hydrophilic layer and a stripping layer that is strippably adhered to the image-forming layer. The image-forming layer is comprised of a photopolymerizable composition comprising a polymeric binder, a plurality of addition-polymerizable ethylenically-unsaturated compounds at least one of which possesses phosphorus-derived acidic functionality and a photopolymerization initiator. After imagewise exposure of the plate to activating radiation, the stripping layer is peeled from the image-forming layer with only the unexposed regions of the image-forming layer adhering thereto so as to reveal the underlying hydrophilic layer and thereby form a lithographic printing surface.

  一种可剥离显影平版印刷板由基底、覆盖在基底上的由聚合物酸组成的亲水层、覆盖在亲水层上的辐射敏感图像形成层和可剥离地粘附在图像形成层上的剥离层组成。图像形成层由可光聚合的组合物组成，该组合物包括聚合物粘合剂、多种可加成聚合的乙烯基不饱和化合物（其中至少一种具有磷衍生的酸性官能团）和光聚合引发剂。将印版按图像方向暴露在活化辐射下后，剥离层从图像形成层上剥离，只有图像形成层的未暴露区域附着其上，以显示底层亲水层，从而形成平版印刷表面。
