| titleOfInvention | Hot melt adhesive |
| abstract | PROBLEM TO BE SOLVED: To provide a hot melt adhesive having a small amount of adhesive residue on an adherend at the time of peeling, a high tack property and a high holding power. SOLUTION: This is a hot melt pressure-sensitive adhesive containing a (co) polymer (A) containing a monomer (a1) represented by the general formula (1) as an essential constituent monomer, and the above-mentioned (co). The weight average molecular weight of the polymer (A) is 400,000 to 800,000, the molecular weight distribution (Mw / Mn) of the (co) polymer (A) is 2.5 to 4.0, and gel permeation chromatograph. In the differential molecular weight distribution curve of the (co) polymer (A) obtained from the elution curve of the graphic (GPC) analysis, the ratio of the area area in the range of the molecular weight of 50,000 or less is obtained from the differential molecular weight distribution curve. A hot melt pressure-sensitive adhesive having a content of 1 to 5% with respect to the total area of the area and a residual monomer content of 0.005 to 0.15% by weight based on the weight of the hot melt pressure-sensitive adhesive.
