Method for Preparing Aqueous Pressure-Sensitive Adhesive Composition for Clothing

A method for preparing an aqueous pressure-sensitive adhesive composition for clothing, comprising:

• emulsion polymerizing a monomer mixture in the presence of an emulsifier, wherein the monomer mixture comprises:
• a (meth)acrylic acid ester-based monomer containing a C1 to C14 alkyl group;
• and a comonomer,
• wherein the comonomer is at least one comonomer selected from the group consisting of a vinyl ester-based monomer, a styrene-based monomer, a (meth)acrylic acid-based monomer, and a monomer represented by the following Chemical Formula 1,
• wherein in the monomer mixture, the (meth)acrylic acid-based monomer is included in an amount of 0.1 wt % to 2.5 wt %, and the monomer represented by the following Chemical Formula 1 is included in an amount of 0.1 wt % to 0.3 wt %,
• wherein the emulsifier comprises:
• a first emulsifier and a second emulsifier,
• wherein the first emulsifier is a sodium polyoxyethylene alkyl ether sulfate-based compound containing a C1 to C14 alkyl group, and
• wherein the second emulsifier is at least one selected from the group consisting of a diaryl oxide disulfonate-based compound containing a C6 to C20 aryl group, a dialkyl sodium sulfosuccinate-based compound containing a C1 to C14 alkyl group, and a sodium alkyl sulfate-based compound containing a C1 to C14 alkyl group, wherein the second emulsifier comprises at least one of the diaryl oxide disulfonate-based compound and the sodium alkyl sulfate-based compound, and
• wherein the emulsifier is used in 0.5 parts by weight to 1.6 parts by weight based on 100 parts by weight of the monomer mixture, and the second emulsifier is used in a weight ratio of 0.3 to 0.6 based on a weight of the first emulsifier,
• wherein,
• R1 and R2 are the same as or different from each other, and are each independently hydrogen or a C1 to C10 alkyl group,
• A is —CH2—O—, —(C═O)-0-, or —(C═O)—NR3—,
• X is a single bond or a C1 to C10 alkylene group, wherein at least one hydrogen of the alkylene group is substituted with a hydroxy group, Y is a single bond, an oxygen atom, or —NR4—, and Z is a single bond or a C1 to C10 alkylene group;
• X and Y are one single bond;
• or X, Y, and Z are one single bond,
• R3 is hydrogen or a C1 to C10 alkyl group, and
• R4 is hydrogen or a C1 to C10 alkyl group.
