Abstract
(EN)
The present invention relates to novel waterborne adhesives which are polymerisable by UV light and are capable of being activated by heat, and which particularly display good adhesion to difficult substrates, such as ethylene vinyl acetate copolymers (EVA) with a low vinyl acetate content, or rubber. The invention further provides a novel method in which, after the application of the waterborne adhesive to an article and drying, irradiation with UV light and at the same time or thereafter activation by heat are performed. The adhesive film which is irradiated and activated in this way is then bonded to a further article. The invention also provides the use of the adhesives to make items such as shoes.

(FR)
La présente invention porte sur de nouveaux adhésifs à l'eau qui sont polymérisables par la lumière ultraviolette et qui peuvent être activés par la chaleur et qui présentent en particulier une bonne adhérence à des substrats difficiles, tels que des copolymères d'éthylène-acétate de vinyle (EVA) à faible teneur en acétate de vinyle ou le caoutchouc. L'invention concerne un nouveau procédé selon lequel, après application de l'adhésif à l'eau sur un article et son séchage, on applique des rayonnements de lumière ultraviolette et, conjointement ou dans un deuxième temps, on effectue une activation thermique. On colle ensuite le film adhésif qui est exposé à des rayonnements et ainsi activé, sur un autre article. L'invention porte également sur l'utilisation de ces adhésifs pour fabriquer des articles tels que des chaussures.
