Abstract:
An acrylic emulsion obtained bycarrying out a polymerization reaction of a first acrylic monomer dispersion,adding a second acrylic monomer dispersion to said first acrylic monomer dispersion, andcarrying out a further polymerization reaction wherein said first acrylic monomer dispersion contains acrylic monomer and tackifier in a first proportion to acrylic monomer contained in said first acrylic monomer dispersion, and said second acrylic monomer dispersion contains acrylic monomer and tackifier in a second proportion to acrylic monomer contained in said second acrylic monomer dispersion, and wherein the proportion of tackifier in said first acrylic monomer dispersion is lower than the proportion of tackifier in said second acrylic monomer dispersion.
