PURPOSE: An aqueous expansion solution is provided to prevent dust from being fallen even if unevenness section is rubbed with the hand after unevenness is formed and to ensure environment-friendly property using water as a solvent. CONSTITUTION: An aqueous expansion solution is obtained by adding expandable polymeric microsphere and other additives into aqueous emulsion in which a polymer is emulsified and dispersed in water. The aqueous emulsion has one selected from styrene butadiene polymer emulsion, acrylic polymer emulsion, vinyl acetate polymer emulsion, and other aqueous emulsion. |
