Metal organic coatings for anionic substrates

Abstract

Abstract THE INVENTION PROVIDES GLASS ARTICLES COATED WITH THE COMPLEX REACTION PRODUCT OF ANHYDROUS TRIMETHYL BORATE WITH THE ANHYDROUS CHLORIDE OF THE METAL SELECTED FROM TI (IV), ZR (IV) AND HF (IV). THIS RECATION PRODUCT IS WATER-SOLUBLE BUT WHRN APPLIED TO THE SURFACE OF GLASS AND DRIED IS SUBSTANIALLY WATER-INSOLUBLE. THE COATED GLASS SURFACE IS DELUSTERED AND WATER REPELLENT. THIS REACTION PRODUCT HAS A HIGH AFFINITY NOT ONLY FOR GLASS BUT ALSO FOR COMPOUNDS HAVING FREE HYDROXYL GROUPS. CONSEQUENTLY, THE GLASS ARTICLE MAY BE COATED WITH THE COMPLEX REACTION PRODUCT, AND WHEN DRIED MAY BE AGAIN COATED WITH A SOLUTION OR EMULSION OF A HYDROXYLIC COMPOUND AND WHEN DRIED IS CAPABLE OF BEING DYED WITH VAT DYES OR OTHER DYES COMMONLY USED FOR DYEING CELLULOSE FIBERS.. THE INVENTION ALSO PROVIDES AQUEOUS SOLUTION OF POLYVINYL ALCOHOL AND THE REACTION PRODUCT OF ANHYDROUS TRIMETHYL BORATE AND THE ANHYDROUS TETRACHLORIDE OF TI (IV), ZR (IV) AND HF (IV) WHICH MAY BE USED TO COAT VARIOUS SUBSTRATES, SUCH AS COTON, GLASS, LEATHER, PAPER AND STARCH WHICH WHEN DRIED FORMS AND ADHERENT COATING ON THE SUBSTRATE WHICH MAY BE DYED.
