A water soluble resin obtainable by reacting at least a polyamine and a urea compound, or at least a polyamine, a urea compound, a dibasic carboxylic acid compound and a lactam, followed by reacting the reaction product thus obtained with a cross-linking compound selected from epihalohydrins, α,γ-dihalo-β-hydrins, glycidyl compounds and isocyanates is provided. The water soluble resin may be used in a paper coating composition in admixture with a pigment and an aqueous binder. The paper coating composition does not generate formaldehyde and can give coated papers with various improved properties including excellent ink acceptability and water resistance.
