Abstract (en)

[origin: EP1384768A1] A solvent free, hot melt adhesive composition to be used for bonding a polar leather layer to a non-polar substrate, comprising: (a) a block copolymer, comprising at least one acid functionalized, selectively hydrogenated inner block predominantly derived from a conjugated diene which block has been functionalized by acid grafting, and at least two terminal blocks, predominantly derived from a vinylarene; (b) a hydrogenated hydrocarbon tackifying resin, with a softening point lower than 140 DEG C. in a weight proportion of 30 to 150 PHR (parts by weight of tackifying resin per 100 parts per weight of block copolymer); (c) a resin which is compatible with the predominantly poly(vinylarene) blocks, having a softening point lower than 140 DEG C in a weight proportion of from 10 to 80 PHR; (d) optionally a melt flow improving poly(alkylene) resin, which has been functionalized, in a weight proportion of from 0 to 30 parts PHR, and (e) stabilizers and/or additional auxiliaries in a weight proportion of from 0.1 to 1 PHR, as well as its use for bonding a polar leather layer to a non-polar substrate and formed leather articles composed by means of said adhesive composition.
