Patent

CA 2339617

The invention relates to a composition containing: (a) 0 to less than 1% by weight of a pigment (I) with a primary par-ticle size of 5 nm to 100 m, which is a solid (a) or a com-pound (Ib) acting as cathodic material in electrochemical cells or a compound (Ic) acting as anodic material in electrochem-ical cells or a mixture of solids (Ia) with compound (Ib) or com-pound (Ic); (b) over 99 to 100 % by weight of a polymer ma-terial (II) comprising (IIa) 1 to 100 % by weight of a polymer or copolymer (IIa) having a re-active groups (RG) in the chain, end or side thereof, which are ca-pable of cross-linking reactions by the application of heat and/or UV radiation and (IIb) 0 to 99 % by weight of at least one polymer or copolymer (IIb) free from re- active groups (RG).

Composition contenant : a) 0 à moins de 1 % en poids d'un pigment (I) dans lequel la taille des particules primaires est comprise entre 5 nm et 100 mu m, qui peut être soit une matière solide (Ia), soit un composé (Ib) servant de matériau cathode dans les piles électrochimiques, soit un composé (Ic) servant de matériau anode dans les piles électrochimiques, soit un mélange de la matière solide (Ia) avec le composé (Ib) ou le composé (Ic); b) plus de 99 à 100 % en poids d'un matériau polymère (II) comprenant: (IIa) 1 à 100 % en poids d'un polymère ou copolymère (IIa) comportant des groupes réactifs (RG) situés au niveau de la chaîne, en extrémité ou latéralement, qui peuvent être réticulés par la chaleur et/ou par un rayonnement ultraviolet; et (IIb) 0 à 99 % en poids d'au moins un polymère ou copolymère (IIb) dépourvu de groupes réactifs RG.
