Provided is an acrylic emulsion pressure-sensitive adhesive composition, and more particularly, an acrylic emulsion pressure-sensitive adhesive composition which may realize excellent adhesive properties, and may maintain excellent adhesive strength even after aging, in particular, when applied to a curved surface of an adherend, and thus may be usefully applied to labels for bottles, etc.

Acrylic emulsion pressure-sensitive adhesive composition

A gravure coater test apparatus includes a gravure roll and a backup roll which are circumscribed to each other, a motor which drives the gravure roll partially submerged in a water-based pressure-sensitive adhesive for coating, a controller which adjusts the rotational speed of the motor, a doctor blade which is selected from a plurality of types to scrape the water-based pressure-sensitive adhesive from the surface of the gravure roll being rotated, and an infrared analyzer which allows at least one of the type of the water-based pressure-sensitive adhesive corresponding to the selected doctor blade, the uniformity of the coating surface, and the amount of the coated water-based pressure-sensitive adhesive to be confirmed.

A process for preparing an acrylic emulsion resin is provided by introducing specific monomers at a certain time during an emulsion polymerization process, dispersion stability and adhesion properties of the acrylic emulsion resin are improved, thereby providing an aqueous acrylic pressure-sensitive adhesive that not only has excellent initial adhesion but also has low viscosity and improved processability, and high adhesion holding power.
