The deposition process was optimized to obtain homogeneously coated aluminum pigments. The growth of the surface coatings was controlled by investigation with scanning electron microscopy, energy dispersive X\u2010ray spectroscopy and static light scattering as well as infrared, X\u2010ray diffraction and thermogravimetric analysis. The iron precursor showed an incomplete decomposition in solution, incorporating traces of urea molecules inside the coatings while the copper precursor showed complete dissociation accompanied by in\u2005situ formation of amine complexes. The amount of organic residues resulting from ligand fragments in the final oxide coatings could be reduced to 22\u2009% for the iron oxide and 12\u2009% for the copper oxide by further temperature treatment in solution (259\u2009\u00b0C). Colorimetric investigations of the obtained pigments revealed an excellent hiding power, outperforming the pigments used in current state\u2010of\u2010the\u2010art formulations.<\/jats:p>","DOI":"10.1002\/open.202000223","type":"journal-article","created":{"date-parts":[[2020,12,10]],"date-time":"2020-12-10T18:32:13Z","timestamp":1607625133000},"page":"1251-1263","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Environmentally Benign Solution\u2010Based Procedure for the Fabrication of Metal Oxide Coatings on Metallic Pigments"],"prefix":"10.1002","volume":"9","author":[{"given":"Thorsten","family":"Bies","sequence":"first","affiliation":[{"name":"Department of Chemistry Eduard-Zintl-Institut f\u00fcr Anorganische und Physikalische Chemie Technische Universit\u00e4t Darmstadt  Alarich-Weiss-Stra\u00dfe 12 64287 Darmstadt Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rudolf C.","family":"Hoffmann","sequence":"additional","affiliation":[{"name":"Department of Chemistry Eduard-Zintl-Institut f\u00fcr Anorganische und Physikalische Chemie Technische Universit\u00e4t Darmstadt  Alarich-Weiss-Stra\u00dfe 12 64287 Darmstadt Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"St\u00f6ter","sequence":"additional","affiliation":[{"name":"Schlenk Metallic Pigments GmbH  Barnsdorfer Hauptstra\u00dfe 5 91154 Roth Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adalbert","family":"Huber","sequence":"additional","affiliation":[{"name":"Schlenk Metallic Pigments GmbH  Barnsdorfer Hauptstra\u00dfe 5 91154 Roth Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8153-9491","authenticated-orcid":false,"given":"J\u00f6rg J.","family":"Schneider","sequence":"additional","affiliation":[{"name":"Department of Chemistry Eduard-Zintl-Institut f\u00fcr Anorganische und Physikalische Chemie Technische Universit\u00e4t Darmstadt  Alarich-Weiss-Stra\u00dfe 12 64287 Darmstadt Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,12,10]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.3764\/aja.110.3.365"},{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/ar1000082"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1179\/2047058414Y.0000000162"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.porgcoat.2005.07.003"},{"key":"e_1_2_7_5_1","unstructured":"G.
