    Abstract: The invention relates to compositions, comprising. a)1.00 to 65.00% by weight of at least one compound of formula (I), wherein R1, R2, R3, R4 are each independently H, C1-C6-alkyl, C1-C6-alkoxy, or C1-C6-alkoxy-C1-C6-alkyl; R is H or C1-C6-alkyl; X is CR6R7, O, or NR8; R6R7 are each independently H, C1-C6-alkyl, C1-C6-alkoxy, or C1-C6-alkoxy-C1-C6-alkyl; R8 is H, C1-C6-alkyl, or C1-C6-alkoxy-C1-C6-alkyl; k is 1, 2, 3, 4 or 5, as component A; b) 1.00 to 60.00% by weight of at least one monomer having two (meth)acrylate groups and having a molecular weight of no more than 500 Dalton, as component B; c) 0 to 25% by weight of at least one monomer having at least three (meth)acrylate groups and having a molecular weight of no more than 600 Dalton, as component C; and d) 1.00 to 30.00% by weight of at least one polymer having at least two (meth)acrylate groups and having a molecular weight of at least 700 Dalton, as component D; with the proviso that the amount of components A + B is at least 50% by weight, as well as the use of these compositions as printing inks, in particular inkjet printing inks.

    Abstract: The invention relates to a method for producing isosorbide ethoxylate dimethacrylate by the transesterification of alkyl(meth)acrylate with isosorbide ethoxylate, comprising the following steps: (i) ethoxylating isosorbide to isosorbide ethoxylate; (ii) permitting alkyl(meth)acrylate to react with isosorbide ethoxylate in the presence of potassium phosphate as a catalyst and of a stabilizer and in the presence of an entrainer, forming an azeotrope with the alcohol bonded in the alkyl(meth)alcylate; (iii) continuously distilling off the azeotrope that consists of entrainer and alcohol, steps (ii) and (iii) being carried out simultaneously until isosorbide ethoxylate is substantially completely converted; (iv) separating the catalyst from the isosorbide ethoxylate dimethacrylate-containing product mixture; and (v) distilling off non-converted alkyl(meth)acrylate and entrainer from the product mixture.
