PURPOSE:To obtain an aqueous dispersion, capable of providing films excellent in low-temperature adhesiveness to unoxidized PP films and molded products, by dispersing chlorinated polypropylene in water with a water-soluble (meth) acrylic resin having amino groups. CONSTITUTION:An aqueous resin dispersion obtained by dispersing (A) 100pts.wt. chlorinated polypropylene having <=0.1P viscosity (at 25 deg.C in 10wt.% toluene solution) with 15-40wt.% chlorine content in water with (B) 2-20pts.wt. water- soluble (meth)acrylic resin, prepared by at least partially neutralizing a copolymer of 10-80mol.% monomer expressed by formulas I and/or II (R1 is H or methyl; R2 is 1-4C alkylene or hydroxy-substituted alkylene group; R3 and R4 are H or 1-4C alkyl group; A is O or NH) with 90-20mol.% monomer expressed by formula III (R5 is 1-22C alkyl, alkenyl group, etc.) and having amino groups. |
