Claim:
An emulsion of a resin having a function of oxidation inhibition obtained by subjecting an antioxidant (A) having two or more alcoholic hydroxyl groups, an optional polyol compound (B), a compound (C) having a carboxyl group and an active hydrogen group, and an organic polyisocyanate (D) to urethanation reaction in an organic solvent to obtain a resin solution, neutralizing the resin solution with a neutralizing agent (B), and then dispersing the resin solution in water, wherein the antioxidant (A) having two or more alcoholic hydroxyl groups is represented by general formula (1) (wherein R 1 is an alkylene group having 1 to 10 carbon atoms and/or —(CH 2 —CO) m —, R 2 , R 3 , and R 4 each are an alkylene group having 1 to 10 carbon atoms and/or —(CH 2 —O) n —, R 5 is an alkyl group having 1 to 10 carbon atoms or a hydrogen atom, and m and n each are an integer of 1 to 10).
