Method for producing films having a coating the films obtained in this way and their use for producing molded parts in particular for use in automobile construction
摘要：
A process for producing sheets, in which a free-radically crosslinkable coating composition (K) which after crosslinking to completion gives a transparent coating (KE) is applied to a backing sheet (T), a coating (KT), dried but not yet crosslinked to completion, is produced from the coating composition (K), on (KT) a pigmented coating (PB) is produced and optionally on (PB) a tiecoat is applied, the crosslinkable coating composition (K) comprising a free-radically crosslinkable component (KK) based on urethane acrylate and containing carbamate and/or biuret and/or allophanate and/or urea and/or amide groups, (KK) having a number-average molecular weight of from 1000 to 50 000 g/mol, having a double bond content of from 1.0 to 5.0 mol of double bonds per 1000 g of reactive component (KK), containing on average per molecule >1 branching point, containing 5%-50% by weight, based in each case on the weight of component (KK), of cyclic structural elements, and containing at least one aliphatic structural element having at least 6 carbon atoms in the chain.
摘要（中）：

制造片材的方法，其中在完成交联后得到透明涂层（KE）的可自由基交联的涂料组合物（K）施加到背衬片材（T），干燥但尚未形成的涂层（KT） 交联至完成，由涂料组合物（K）在（KT）上生产着色涂料（PB），并且任选地在（PB）上施涂涂层，所述可交联涂料组合物（K）包含可自由基交联的 基于氨基甲酸酯丙烯酸酯并含有氨基甲酸酯和/或缩二脲和/或脲基甲酸酯和/或脲和/或酰胺基的组分（KK）（KK），其数均分子量为1000至50 000g / mol，具有 每1000克反应性成分（KK）为1.0-5.0摩尔双键的双键含量，每分子平均分子> 1个支化点，含有5％-50％（重量），基于每种反应成分 组分（KK）的环状结构元素，并含有至少一个碱金属 在链中具有至少6个碳原子的结构元件。
