Abstract

The invention relates to the technical field of cohesive bandages. The invention relates to a bandage comprising a flat web material as a substrate, both main sides of the substrate being coated at least partially with a hot-melt adhesive. The invention also relates to a hot-melt adhesive for producing a bandage, to the use of a hot-melt adhesive for producing bandages, and to a method for producing a bandage. The hot-melt adhesive is based on a first polyolefin having—a proportion of 1-butene-derived monomer units; a proportion of ethylene-derived monomer units; and the hot-melt adhesive further comprises: at least one tackifier consisting of hydrocarbon resin and/or of hydrogenated hydrocarbon resin. The hot-melt adhesive can also contain a second polyolefin, preferably an amorphous polypropylene homo- or copolymer.

Abstract

The invention relates to adhesive compositions which show - a first colour change when the ambient temperature is increased to a temperature of = T1 and - a second colour change when the ambient temperature is lowered to a temperature of = T2, wherein ?1 > T2. Such adhesive compositions have advantageous properties, in particular at security applications.
