Hydrophilic curable resin composition for preparing hydrophilic resin coating films on articles, which contains, as the resinous component, a polyether ester consisting of 60 to 10 % by weight of non-hydrophilic portion and 40 to 90 % by weight of a hydrophilic polyether portion forming the main chain of the molecule, and said non-hydrophilic portion containing 3 or more equivalents of polymerizable ethylenically unsaturated bond component per mole of said polyether ester based on the average molecular weight, and the coating films formed therefrom, which have water resistance and other excellent properties.
