    Abstract: A HMPSA is provided that preferably includes at least a) from 30 to 50% of a mixture of triblock and diblock styrenic copolymers having an overall styrene content comprised between 14 and 40%, b) from 40 to 55% of a tackifying resin with a softening temperature comprised between 70 and 150° C. obtainable by hydrogenating, polymerizing or copolymerizing mixtures of aliphatic unsaturated hydrocarbons having about 5, 9 or 10 carbon atoms; c) from 4 to 20% of a hydrocarbon oil with an aromatic content less than 15%; d) from 1 to 6% of a filler selected among calcium carbonate or a low molecular weight homopolymer or copolymer of polyethylene. A laminated system is also provided that includes at least an adhesive layer utilizing the HMPSA and paper facestock. Also included are PSA labels obtainable from the laminated system with a reduced tendency to discolor after storage.

    Abstract: The invention relates to a method for cross-linking a cross-linkable adhesive composition without solvent on a film, comprising driving and/or guiding said film in a climatic chamber, by a Caroll-type drive or guide.
    The invention also relates to a climatic chamber comprising a Caroll-type drive or guide.
    The invention also relates to a process for manufacturing a self-adhesive article comprising at least a substrate and an adhesive layer, said process comprising the steps of: a) conditioning an adhesive composition at a temperature of between 20 and 160°C; b) coating the adhesive composition b1) onto at least a part of the substrate or b2) onto a non-sticking support; submitting the article obtained at step b) to a controlled atmosphere.
    The invention also relates to self-adhesive articles having high coating weights and to processes for bonding them.
