摘要： A low-monomer PU prepolymer containing free NCO groups which is obtained from polyhydric alcohols and diisocyanates differing in their reactivity and which is distinguished by the ratio of the NCO groups of the partly slower-reacting diisocyanate to the NCO groups of the faster-reacting diisocyanate. It is greater than 6:1. Nevertheless the prepolymer according to the invention cures more quickly than a known prepolymer predominantly containing fast-reacting NCO groups. In a preferred embodiment, TDI is used as the partly slower-reacting diisocyanate while MDI is used as the faster-reacting diisocyanate. The prepolymer is produced in two stages. The prepolymer according to the invention is suitable for bonding plastic articles, metals and paper, especially films. The accelerated absence of migration is particularly noticeable in this regard.
摘要翻译：含有游离NCO基团的低单体PU预聚物，其由多元醇和其反应性不同的二异氰酸酯获得，其特征在于部分较慢反应的二异氰酸酯的NCO基团与较快反应的二异氰酸酯的NCO基团的比例。大于6：1。然而，根据本发明的预聚物比主要含有快速反应的NCO基团的已知预聚物更快地固化。在优选的实施方案中，TDI用作部分较慢反应的二异氰酸酯，而MDI用作较快反应的二异氰酸酯。预聚物分两个阶段生产。根据本发明的预聚物适用于粘合塑料制品，金属和纸，特别是薄膜。在这方面，加速不存在移民尤其明显。

摘要： Organic photoprecursors of amines are provided for use in photosensitive imaging systems, finding particular application in the preparation of lithographic printing plates. Said photoprecursors generate free amines on exposure to long wavelength UV or visible radiation, have high solubility in organic solvents, and include photolabile 2-nitrobenzyl functional groups. Methods for the synthesis of the photoprecursors are described, and the use of the said photoprecursors for the production of printing plates using both positive working and negative working techniques are discussed.
摘要翻译：胺的有机光阳极被提供用于光敏成像系统中，特别适用于制备平版印刷版。所述光阳离子在暴露于长波长UV或可见光辐射下产生游离胺，在有机溶剂中具有高溶解度，并且包括光不稳定的2-硝基苄基官能团。描述了用于合成光阳离子的方法，并且讨论了使用所述光阳离子用于使用正工作和负作用技术来生产印版的方法。
