Claim 8:
9. The method for preparing the diene-based rubber latex of claim 8, wherein the polymer aggregate is prepared by emulsion polymerization comprising:
i) polymerizing 20 to 40 parts by weight of an unsaturated carboxylic acid or an ester monomer thereof in the presence of 0.1 to 0.2 parts by weight of a crosslinking agent; and
ii) injecting and polymerizing 50 to 75 parts by weight of the unsaturated carboxylic acid or the ester monomer thereof and 5 parts by weight to 10 parts by weight of the comonomer having a functional group at a point where a polymerization conversion ratio of the step i) is 85 to 95%, based on 100 parts by weight of a total amount of the unsaturated carboxylic acid or the ester monomer thereof and the comonomer having a functional group.
