Patent

CA 2588003

The invention is a composition comprising a) one or more organotitanates or zirconates having four ligands wherein the ligands are hydrocarbyl, optionally containing one of more functional groups having one or more heteroatoms selected from the group comprising oxygen, nitrogen, phosphorus and sulfur wherein two or more of the ligands may form a cyclic structure with the proviso that one of the ligands has an acidic moiety; one or more strong organic acids or a mixture thereof ; b) one or more alkoxysilanes; c) optionally one or more high molecular weight resins; and d) a solvent which dissolves the components of the composition. This composition is referred to as a clear primer hereinafter. Preferably, the composition comprises both an organotitanate or zirconate and a strong acid.

L'invention concerne une composition qui comprend : a) un ou plusieurs organotitanates ou zirconates comprenant quatre ligands qui sont des ligands hydrocarbyle, contenant éventuellement un ou plusieurs groupes fonctionnels ayant un ou plusieurs hétéroatomes choisis dans le groupe constitué d'oxygène, azote, phosphore et soufre, au moins deux des ligands pouvant former une structure cyclique à la condition qu'un des ligands comprenne une fraction acide ; un ou plusieurs acides organiques forts ou un mélange de ces derniers ; b) un ou plusieurs alcoxysilanes ; c) éventuellement une ou plusieurs résines à poids moléculaire élevé ; et d) un solvant qui dissout les composants de la composition. La composition est désigné ci-après sous le terme d'amorce incolore. De préférence, la composition comprend un organotitanate ou un zirconate et un acide fort.
