摘要： The invention relates to a process for the manufacture of coatings by radiocrosslinking. A radio-crosslinkable composition (C) is produced first of all by mixing at least one (meth)acrylic compound (A) with a reactive diluent system comprising at least one mono(meth)acrylic carbonate (B) corresponding to the general formula (I): ##STR1## in which: R.sub.1 denotes H or CH.sub.3R.sub.2 denotes an alkylene ether or alkylene chain which has a total number of carbon atoms of between 2 and 6,n denotes an integer between 1 and 6.The composition (C) is next applied onto a substrate and is then radiocrosslinked, preferably using UV radiation.Another subject of the invention is the crosslinkable compositions (C) in which the compound (A) and the carbonate (B) are not simultaneously 2,3-carbonyldioxypropyl 2-methacryloyloxyethyl carbonate, and carbonates of general formula (I) in which R.sub.2 denotes (CH.sub.2).sub.m and in which m and n are integers such that 2.ltoreq.m.ltoreq.6, 1.ltoreq.n.ltoreq.6 and n.noteq.1 when m=2 and R.sub.1 denotes CH.sub.3. The carbonates of general formula (I) are highly photosensitive, and this allows irradiation times which are very markedly shorter than those used hitherto with mono(meth)acrylic diluents, or else makes it possible to photocrosslink in the absence of photoinitiator.
摘要翻译：本发明涉及通过无线电交联制造涂料的方法。首先通过将至少一种（甲基）丙烯酸化合物（A）与包含对应于通式（A）的至少一种单（甲基）丙烯酸酯碳酸酯（B）的反应性稀释剂体系混合来制备无线电交联组合物（C） I）：其中：R1表示H或CH3R2表示碳原子数为2〜6的亚烷基醚或亚烷基链，n表示1〜6的整数。组合物（C）接下来施加到基底上，然后放射交联，优选使用UV辐射。本发明的另一个主题是其中化合物（A）和碳酸酯（B）不同时是2-甲基丙烯酰氧基乙基碳酸2,3-二甲基丙烯酰氧基乙酯和通式（I）的碳酸酯的可交联组合物（C），其中R2表示（CH 2）m，其中m和n是整数，使得当m = 2且R 1表示CH 3时，2≤n≤6,1或n = 6和n等于1。通式（I）的碳酸酯是高度光敏的，这允许比迄今使用的单（甲基）丙烯酸稀释剂显着缩短的照射时间，或者使得在不存在光引发剂的情况下可以进行光致交联。
