Abstract:
Pressure-sensitive hot-melt adhesive composition comprising:a) at least one ethylene-vinyl acetate, ethylene methyl acrylate or ethylene-butyl acrylate copolymer; said ethylene-vinyl acetate, ethylene methyl acrylate or ethylene-butyl acrylate content in the copolymer is between 30 and 50%,b) a solid tackifying resin having a ring-and-ball softening point of between 60 and 140.degree. C.,c) a liquid tackifying resin having a ring-and-ball softening point lower than 40.degree. C.,d) an antioxidant, ande) optionally a diluent.wherein said adhesive composition is from 30 to 50% by weight of copolymer, from 10 to 40% by weight of solid tackifying resin, from 10 to 40% by weight of liquid tackifying resin, from 0.1 to 2% by weight of antioxidant and from 0 to 20 % by weight of diluent.
