PURPOSE:To produce the titled composition having excellent water-resistance, shear strength, peel strength and holding power, by compounding a urethane emulsion having a specific fine particle diameter with a crosslinking agent. CONSTITUTION:The objective composition contains (A) a urethane emulsion having particle diameter of 0.001-0.1mu, preferably 0.001-0.05mu and (B) preferably 0.1-30(wt)% crosslinking agent (e.g. epoxy compound, compound containing methylol group, isocyanate, etc.) based on 100pts of the solid content of the component A. The composition is used usually as a water-based pressure- sensitive adhesive or an impregnating or coating material for various substrates.
