Abstract
The invention relates to biodegradable hot-melt adhesive compositions, preferably without residual tackiness at room temperature and having a biodegradability, as measured by the released carbon-dioxide analysis method pursuant to Standard EN ISO 14855, that is higher than 55% , preferably higher than 60% , and preferably higher than 90% , and to the use thereof. This percentage is given by reference with the cellulose biodegradability measurement, which amounts to 100% in the same conditions.
