Aux fins des lois sur la lutte contre la corruption, les représentants gouvernementaux comprennent : • les dirigeants et les employés d’un gouvernement (fédéral, provincial, local), d’un ministère ou d’une agence; • toute personne agissant à titre officiel au nom ou pour le compte de tout gouvernement, ministère ou agence; Table des matières 3 • des partis politiques, les représentants de partis politiques et les candidats à une charge publique; • les membres de la direction et les employés d’entreprises commerciales publiques ou encore détenues ou contrôlées par un gouvernement ou l’État, y compris les entités détenues en partie; • les membres de la direction et les employés d’organisations internationales publiques, tels que les Nations Unies.

The majority of today’s most popular bleed-resistant plastisol inks use a bleed-resistant technology which is odorless and the bleed resistance is superior to the peroxide predecessors. 3.
