Abstract

Abstract Translated from German Beschichtungen aus Polyisocyanaten, die einen latenten Katalysator der Formel I enthalten, [ (R¹) Fe II (R²) ] [X] a ⁻      I worin a 1, 2 oder 3 ist, R¹ ein ungeladener carbocyclischer oder heterocyclischer, unsubstituierter oder substituierter aromatischer Ring ist, R² ein unsubstituiertes oder substituiertes Cyclopentadienyl- oder Indenyl-Anion ist und [X] a ⁻ ein Anion aus der Reihe F⁻, Cl⁻, Br⁻, I⁻, CN⁻, NCO⁻, NCS⁻, CH₃COO⁻, CF₃COO⁻, SO₄²⁻, PO₄³⁻, NO₃⁻, ClO₄⁻, [(Phenyl)₄B]⁻, C₆H₅SO₃⁻, CH₃C₆H₄SO₃⁻, CF₃C₆H₄SO₃⁻, CH₃SO₃⁻, CF₃SO₃⁻, C₄F₉SO₃⁻, C₆F₁₃SO₃⁻, C₈F₁₇SO₃⁻, C₆F₅SO₃⁻, BF₄⁻, AlF₄⁻, AlCl₄⁻, TiF₆²⁻, PF₆⁻, SbF₆⁻, SbCl₆⁻, GeF₆⁻, ZrF₆²⁻, AsF₆⁻, FeCl₄⁻, SnF₆⁻, SnCl₆⁻ oder BiCl₆⁻ darstellt, lassen sich durch Bestrahlung mit aktinischem Licht und anschliessendes Erwärmen härten. Coatings made from polyisocyanates containing a latent catalyst of the formula I, [(R¹) Fe II (R²)] [X] a ⁻ I wherein a is 1, 2 or 3, R¹ is an uncharged carbocyclic or heterocyclic, unsubstituted or substituted aromatic ring, R² is an unsubstituted or substituted cyclopentadienyl or indenyl anion and [X] a ⁻ is an anion from the series F⁻, Cl ⁻, Br⁻, I⁻, CN⁻, NCO⁻, NCS⁻, CH₃COO⁻, CF₃COO⁻, SO₄²⁻, PO₄³⁻, NO₃⁻, ClO₄⁻, [(phenyl) ₄B] ⁻, C₆H₅SO₃⁻, CH₃C₆H₄SO₃⁻, CF₃C₆H₄SO₃ ⁻, CH₃SO₃⁻, CF₃SO₃⁻, C₄F₉SO₃⁻, C₆F₁₃SO₃⁻, C₈F₁₇SO₃⁻, C₆F₅SO₃⁻, BF₄⁻, AlF₄⁻, AlCl₄⁻, TiF₆²⁻, PF₆⁻, SbF₆⁻, SbCl₆⁻, GeF₆⁻, ZrF₆²⁻, AsF₆⁻, FeCl₄⁻, SnF₆⁻, SnCl₆⁻ or BiCl₆⁻, can be hardened by irradiation with actinic light and subsequent heating.
