A radiation curable liquid includes at least one free radical polymerizable monomer or oligomer, at least one diffusion hindered acetalysation catalyst, and at least one diffusion hindered hydroxyl containing compound. The radiation curable liquid applied to a substrate prevents migration of very low viscous monomers, such as vinyl ether acrylate monomers, into the substrate.
一种辐射固化液体包括至少一种自由基聚合单体或寡聚物,至少一种扩散受阻的缩醛化催化剂和至少一种扩散受阻的含羟基化合物。将这种辐射固化液体应用于基材上可以防止非常低粘度的单体(例如乙烯醚丙烯酸酯单体)向基材中扩散。

An inkjet printing method includes the steps of a) providing a first radiation curable composition curable by free radical polymerization or cationic polymerization; b) applying a layer of the first radiation curable composition on a substrate; c) curing the layer; d) jetting on the cured layer a second composition curable by a different polymerization than the first composition but selected from the group consisting of free radical polymerization and cationic polymerization; and e) curing the jetted second composition by a different polymerization than the first composition. The first composition includes a cationically polymerizable compound having at least one (meth)acrylate group present in the first curable composition in an amount of at least 25 wt % based upon the total weight of the first curable composition. An inkjet ink set may be used in the above inkjet printing method.
