(57) [Summary] [Constitution] It contains an amorphous polyolefin having a number average molecular weight of 1,000 to 20,000 and a propylene component of 20% by weight or more and a tackifier, and is transparent in a molten state. A hot melt adhesive characterized by being opaque at room temperature. [Effect] The hot-melt adhesive of the present invention can reduce the bleeding into the moisture-permeable olefin resin film, does not cause phase separation during melting, and has an appropriate viscosity, so that the coating performance is good. is there. |
