- the aqueous dispersion compositions of Examples and Comparative Examples were prepared by including a wax-based anti-blocking agent of the type and amount shown in Table 1 in the aqueous dispersion composition.
- the weight average molecular weight (Mw) and number average molecular weight (Mn) of the sample were measured using a GPC system (PL-GPC220 (Agilent)) connected to a refractive index detector and a polystyrene standard.
- PDI (Mw/Mn) was calculated using the measured Mw and Mn.
- the melting point was measured using a differential scanning calorimeter (Differential Scanning Calorimeter, measuring instrument: TA company Q20).
- the temperature was raised to 10 o C/min in the range of -50 to 180 o C (the first heating section), and then maintained isothermal at 180 o C for 1 minute. After that, the sample was crystallized by cooling from 180 o C to -50 o C at a rate of 10 o C/min. Second, change the temperature in the temperature rising region in -50 ⁇ 180 o C, 10 o C / min , and was measured temperature (Tm) of melt peaks generated in the second temperature rising region, the peak areas of the 80 o C or less The ratio was calculated.
- Measurements were made as follows based on ASTM F88 (measurement device: Instron), and a specimen having a size of 250 x 10 mm was prepared through a device (Gradient Heat Seal Tester) conforming to ASTM F2029.
- the aqueous dispersion composition was brought into contact with the coated substrate and the non-coated substrate, placed in a gradient test device, and adhered at a constant temperature of 2 bar and 1 sec. After being left in a constant temperature and humidity room for 24 hours, the specimen was engaged with the specimen up and down in a tensile tester, and then pulled at a speed of 300 mm/min, and the section in which the force was constant was measured as an average.
- Comparative Example 4 having a wax content of 3% by weight, anti-blocking properties were not substantially realized.
