摘要： A 3D extrusion print process for producing multicolored three-dimensional objects is provided. The process produces mechanically stable, multicolored 3D objects with good color definition. The process according to the invention is based on coating, upstream of the printing head, of the polymer strand used for producing the actual object, and on fixing of the coating upstream of entry of the polymer strand into the printing head. Downstream of the extrusion process in the printing head, the coating remains predominantly at the surface of the extruded strand.

摘要： A low monomer 1:1-monoadduct from a diisocyanate and a hydroxy(meth)acrylate with a free diisocyanate content of less than 0.7% by weight and a free NCO content of 10.4-16.4% by weight can be used as a starting material for an acrylic or NCO functionalized crosslinker; a bonding agent for coatings and adhesives; and a linker for solid-phase synthesis of oligo-nucleotides, polynucleotides or peptides. The monoadduct is obtained by converting 5-20 mol diisocyanate with 1 mol hydroxy(meth)acrylate at a temperature of 40-120° C. in the presence of at least one inhibitor; subsequently separating a non-converted diisocyanate from a reaction product by short-path distillation at 80-220° C./0.1-10 mbar; feeding air, nitrogen monoxide or oxygen or a mixture containing (a) air, oxygen or nitrogen monoxide and (b) a proportion of 1-90% by volume of carbon dioxide, nitrogen, an inert gas or a mixture thereof through a reaction apparatus.
