Nouveaux complexes du platine utiles, notamment, comme catalyseurs d'hydrosilylation photoactivables et procédé en faisant application.

摘要

Novel platinum-based organometallic complexes for use particularly as a hydrosilylation cross-linking catalyst for Si-H type polyorganosiloxanes (A) and aliphatically unsaturated and/or reactive-functional compounds (B). Said complexes are of formulae (Ia) and (Ib), wherein R<1>=R<2>=R<3>=CH3= and R<4>=R<5>=H. Light-cross-linkable compositions containing polyorganosiloxanes (A) and (B) and catalysts including the above-mentioned complexes are disclosed. The complexes are useful in a non-stick silicone coating for paper.
