PROBLEM TO BE SOLVED: To obtain a composition excellent in a sealability of a corrugated carton and in retention by constituting of an emulsion which contains an acrylic polymer including an acrylic monomer and an acrylamide monomer as monomer units, and contains another acrylic polymer including an acrylic monomer and an ethylenically unsaturated carboxylic acid as monomer units. SOLUTION: This composition comprises an emulsion which contains an acrylic polymer including: 79-99 wt.% (hereinafter, represented as just %) of an acrylic monomer represented by the formula, CH2=C(R1)COOR2; 1-10% of an acrylamide monomer represented by the formula, CH2=C(R3)CONR4R5; and 0-20% of other copolymerizable monomer, as monomer units, and contains another acrylic polymer including: 79-99% of an acrylic monomer represented by the formula, CH2=C(R1)COOR2; 1-7% of an ethylenically unsaturated carboxylic acid (anhydride); and 0-20% of other copolymerizable monomer as monomer units. In the formulas, R1 is H or CH3; R2 is a 1-14C alkyl; R3 is R1; R4 and R5 are each H or a 1-4C alkyl or the like. |
