FIELD: printing.

SUBSTANCE: invention relates to a composition suitable for printing, containing a) 3.00 to 50 wt.% of at least one compound by the formula (I), wherein R¹, R² each independently constitutes H or C₁-C₆-alkyl; R³, R⁴, R⁵ each independently constitutes N or₁-C₆-alkyl; R⁶ constitutes H or C₁-C₆-alkyl; k equals 1, 2, or 3, as component A; b) 5.00 to 55 wt.% of at least one monomer with two (met)acrylate groups and a molecular weight M_w of no more than 500 daltons, as component B; c) 0.50 to 22.50 wt.% of at least one monomer with at least three (met)acrylate groups and a molecular weight M_w of no more than 600 daltons, as component C; d) 3.00 to 25.00 wt.% of at least one polymer with at least two (met)acrylate groups and a molecular weight M_w of at least 700 daltons, as component D; e) 3.00 to 15.00 wt.% of one or more photoinitiators as component E; f) 0.10 to 7.50 wt.% of one or more dyes as component F; g) 0.01 to 1.50 wt.% of one or more intra-container stabilisers as component G; h) 0.00 to 40.00 wt.% of one or more additional monomers selected from N-vinyl compounds, O-vinyl compounds, divinyl compounds, hydroxyvinyl compounds, 1,2,4-trivinylcyclohexane, and mixed acrylate/vinyl ether compounds as component H; j) 0.10 to 7.50 wt.% of one or more additional additives selected from dispersing agents, fillers, auxiliary agents for modifying the rheological properties, sliding agents, levelling agents, substrate wetting agents, antifoaming agents, antistatic additives and antioxidants, as component J; provided that the amount of component A plus B is at least 50 wt.% based on the sum of components A to J, and that in all cases the sum amount of components A to J is 100 wt.%. The invention also relates to a method for printing based on the described composition.

EFFECT: production of a new composition, applicable as printing inks, in particular, inks for inkjet printing.
