    摘要: The present invention relates to an aqueous radiation curable composition comprising: (I) at least one ethylenically unsaturated compound (A), and (II) at least one emulsifier (B) comprising alternating polyalkylene oxide segments, wherein said emulsifier optionally bears one or more groups selected from alkyl groups, aryl groups hydroxyl groups and/or ethylenically unsaturated groups, and wherein said emulsifier (B) has an HLB value of at least 4.5, preferably at least 7. The compositions of the invention are particularly suited for the manufacture of sprayable eco-friendly hardcoats, but they are also suitable for the making of inks, overprint varnishes and adhesives, alone or in combination with e.g. a water-borne polymer dispersion.

    摘要: An aqueous radiation curable composition containing at least one ethylenically unsaturated polyurethane (A) and at least one ethylenically unsaturated polyurethane (B), different from the polyurethane (A), said ethylenically unsaturated polyurethane (B) preferably being characterized by a molecular weight that is below 10,000 Daltons; and optionally, at least one ethylenically unsaturated compound (C) different from (A) and (B); wherein the radiation curable composition in dry form has a steady-state creep viscosity η30, expressed as the apparent viscosity after a deformation time of 30 minutes with a load σO=50 Pa at 23° C., that is above 1·103 Pa·s, more preferably above 1·104 Pa·s. The compositions are characterized by an improved creep viscosity η30 and provide polymer materials with a good flow and mirror effect. In general, these materials are less sensitive to dust pick-up and fingerprints. Further provided is a one-vessel solvent free process for preparing such materials.
