Abstract
An adhesive composition containing 55 to 75% of a continuous phase and 25 to 45% of a discontinuous phase constituted of hydrophilic polymers in the form of hydrocolloids, the continuous phase containing 5 to 10% of a textured copolymer constituted of a styrene-isoprene-styrene or styrene-butadiene-styrene sequence copolymer having a majority of at least triple sequences, more than 22% of a tackifying agent, and 10 to 30% of a plasticizer, these percentages being indicated with regard to the whole of the composition. The tackifying agent is a mixture of tackifying agents that contain a majority of high-activity tackifying agents based on terpene resins, and a significant quantity of a tackifying agent with a low activity of adhesiveness but having reinforcing properties. At least half of the tackifying agent is constituted of a high-activity tackifying agent based on terpene resin such as a terpene-styrene polyterpene resin.
