摘要： A mixture of at least two compounds respectively comprising at least two double bonds. The mixture has a GFV 200-600 g/mol bond and at least two of the compounds respectively contain at least two (Meth)acrylic acid esters as double bond components . GFV represents the following: (cf formula (I)); αi corresponds to the molar fraction of the compound (i) in the mixture, n corresponds to the number of compounds in the mixture and n is = 2, Zi corresponds to the number of double bonds in the compound (i), MWi corresponds to the molecular weight of the compound (i).
