PROBLEM TO BE SOLVED: To provide an aqueous liquid paste composition having low viscosity excellent in handling, and excellent smooth feel to touch without sticky feel wherein a paste on a paper can be removed by rubbing without sticky feel if it is right after applying and even a small amount thereof results in good adhesion. SOLUTION: The aqueous paste composition comprises 10-45% by mass of a polyurethane resin having at least one silanol group in a molecule, 10-25% by mass of a moisturizing agent, and the rest being water. The polyurethane resin is a reaction product of a polyisocyanate constituent, a polyol constituent, and a compound having a hydrolyzable silicone group. COPYRIGHT: (C)2007,JPO&INPIT
