HOT MELT ADHESIVE, ADHESIVE FILM, COATED ARTICLE, AND METHOD FOR MANUFACTURING COATED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a hot melt adhesive which demonstrates good coating suitability, and hardly flows during heating while preventing increased costs and degradation of the environmental safety of a worker.

SOLUTION: The hot melt adhesive includes: 10-30 wt.% of a polyolefin wax having a softening point of 105-140°C; 10-20 wt.% of an elastomer; 25-40 wt.% of a tackifier; and 25-40 wt.% of a softening agent. The hot melt adhesive is preferably such that X>Y and X-Y is at least 5 when X[°C] is the temperature at which the viscosity during heating is 500 Pa s, and Y[°C] is the temperature at which the viscosity during cooling is 500 Pa s.
