A gel-form pressure-sensitive adhesive which comprises an elastomer component (A), a pressure-sensitive adhesive polymer component (B) compatible therewith, and a liquid component (C) compatible with components (A) and (B) and held in the mixture of components (A) and (B) without oozing out, and is in the form of gel as a whole. It is useful for forming the pressure-sensitive adhesive layer of an adhesive material or the drug-containing pressure-sensitive adhesive layer of an adhesive medicinal preparation which layers tenaciously adhere to a surface, in particular the skin of a living body, are easily strippable, and leave no adherent residue on the surface.

L'invention concerne un adhésif sensible à la pression, sous forme de gel, renfermant un constituant élastomère (A), un constituant polymère (B) adhésif sensible à la pression compatible avec le constituant (A), et un constituant liquide (C) compatible avec les constituants (A) et (B), maintenu dans le mélange des constituants (A) et (B) sans suinter, le tout se présentant sous forme d'un gel. Ledit adhésif est utilisé pour former la couche d'adhésif sensible à la pression d'une matière adhésive ou pour former la couche d'adhésif sensible à la pression renfermant des médicaments d'une préparation médicale adhésive dont les couches adhèrent fortement sur une surface, en particulier sur la peau d'un être vivant, couches adhésives qui sont facilement pelables et qui ne laissent pas de reste collant sur la surface.
