The present disclosure relates to a photoinitiating composition suitable for UV-LED light irradiation comprising: a) a photoinitiating system suitable for LED light irradiation having a wavelength in the range of 340-420 nm; b) a dispersing medium; wherein the dispersing medium comprises an organic solvent which is miscible with water.

Photoinitiating composition suitable for UV-LED light irradiation and an aqueous coating composition prepared therefrom

Provided are a UV-curable non-isocyanate polyurea polymer and a UV-curable coating composition containing the same. The UV-curable non-isocyanate polyurea polymer has one or more ethylenically unsaturated functional groups and the ethylenically unsaturated functional groups are attached to nitrogen atoms present in a backbone urea segment via &#x2014;C(=0)- linkage. The nonisocyanate polyurea polymer is prepared by: (i) providing an ethylenically unsaturated compound having one or more carboxylic acid functional groups; and (ii) reacting said ethylenically unsaturated compound having one or more carboxylic acid functional groups with a multi-carbodiimide polymer to form the non-isocyanate polyurea polymer.
