FIELD: chemistry.
SUBSTANCE: present invention to a hot-melt adhesive used in the manufacture of disposable articles. Hot-melt adhesive comprises thermoplastic block copolymer (A), which is a copolymer of vinyl class aromatic hydrocarbons and conjugated diene compounds, wherein thermoplastic block copolymer (A) comprises following component (A1) and component (A2). Component (A1) is a radial type styrene block copolymer having styrene content of 35 to 45 wt%, and diblock copolymer content of 50 to 90 wt% and having a viscosity of a toluene solution containing 25 wt% at 25 °C, which is not more than 250 mPa⋅s. Component (A2) is a styrene block copolymer having styrene content of less than 30 wt%, and having a viscosity of toluene solution, containing 25 wt%, at 25 °C, which is more than 250 mPa⋅s.
EFFECT: invention enables to produce a hot-melt adhesive that is suitable for use at a low temperature and has excellent adhesion to a polyolefin substrate.
