摘要
Acrylic emulsions are obtained by carrying out a polymerization reaction of a first acrylic monomer dispersion, adding a second acrylic monomer dispersion, and carrying out a further polymerization reaction wherein the first acrylic monomer dispersion contains acrylic monomer and tackifier in a first proportion to acrylic monomer contained in the first acrylic monomer dispersion and wherein the second acrylic monomer dispersion contains acrylic monomer and tackifier in a second proportion to acrylic monomer contained in the second acrylic monomer dispersion, and wherein the proportion of tackifier in the first acrylic monomer dispersion is lower than the proportion of tackifier in the second acrylic monomer dispersion. A high molecular weight acrylic polymer is obtained when the first acrylic monomer dispersion is polymerization reacted. The second acrylic monomer dispersion is added to the first acrylic monomer dispersion after the first acrylic monomer dispersion is polymerization reacted. The tackifier is added to the acrylic polymer when the first acrylic monomer dispersion is further polymerized with the second acrylic monomer dispersion. Thus, holding power and adhesion are improved at the same time.
