    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 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.

    IPC: C08G59/56

    Abstract: A curable composition comprises a) at least one epoxide compound E having at least two epoxide groups; b) at least one amine A having at least two amine hydrogens; and c) at least one acrylic ester U; wherein the epoxide compound E comprises at least one epoxide compound E′, the amine A comprises at least one amine A′, and the acrylic ester U comprises at least one acrylic ester U′ whose Hansen solubility parameters for the dipole forces δp and for the specific interactions δh satisfy the following conditions: √{square root over ((δp(U′)−δp(E′))2+(δh(U′)−δh(E′))2)}≥1.5 and √{square root over ((δp(U′)2−δh(U′)2))}−√{square root over ((δp(A′)2+δh(A′)2))}≥0. A suitable choice of the Hansen solubility parameters of the constituents ensures that the acrylic ester is incorporated covalently into the curing material, preventing subsequent evaporation of the diluent.

    Abstract: The invention relates to a process for preparing heonone (meth)acrylate by transesterification of alkyl (meth)acrylate with heonone, which comprises the steps: (i) reaction of alkyl (meth)acrylate with heonone in the presence of a catalyst comprising titanium(IV) or zirconium(IV) and a stabilizer in the presence of an entrainer which forms an azeotrope with the alcohol bound in the alkyl (meth)acrylate, (ii) continuous removal by distillation of the azeotrope of entrainer and alcohol, with steps (i) and (ii) being carried out simultaneously until heonone has been essentially completely reacted, (iii) addition of water to the product mixture comprising heonone (meth)acrylate obtained in steps (i) and (ii) and removal of the hydrolyzate of the catalyst comprising titanium(IV) or zirconium(IV) by filtration, (iv) distillation of unreacted alkyl (meth)acrylate and entrainer from the product mixture, (v) distillation of water from the product mixture, with step (iv) also being able to be carried out before step (iii) and steps (iv) and (v) also being able to be carried out in a distillation step, wherein steps (i) and (ii) are carried out in the presence of an inorganic or organic acid.
