    Abstract: A process for preparing isosorbide di(meth)acrylate by transesterifying alkyl (meth)acrylate with isosorbide, comprising the steps of: (i) reacting alkyl (meth)acrylate with isosorbide in the presence of a catalyst comprising titanium(IV) or zirconium(IV) and a stabilizer in the presence of an azeotroping agent which forms an azeotrope with the alcohol bound in the alkyl (meth)acrylate, (ii) continuously distilling off the azeotrope of azeotroping agent and alcohol, wherein steps (i) and (ii) are conducted simultaneously until the isosorbide has been essentially fully converted, (iii) adding water to the product mixture which comprises isosorbide (meth)acrylate and is obtained in steps (i) and (ii) and removing the hydrolyzate of the catalyst comprising titanium(IV) or zirconium(IV), (iv) distilling unconverted alkyl (meth)acrylate and azeotroping agent out of the product mixture, (v) distilling off water from the product mixture, wherein step (iv) can also be conducted before step (iii) and steps (iv) and (v) can also be conducted in one distillation step.

    Abstract: The invention relates to compositions, having a) 1.00 to 65.00% by weight of at least one compound of formula (I), wherein R1, R2 are each independently H, C1-C6-alkyl, or C1-C6-alkoxy-C1-C6-alkyl; R3, R4, R5 are each independently H, C1-C6-alkyl, or C1-C6-alkoxy-C1-C6-alkyl; R6 is H or 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 1 having a molecular weight Mw 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 Mw 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 Mw 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.
