Abstract: The aluminium alkoxy-hydride compound is new. - An aluminium alkoxy-hydride compound of formula Al(OR)aHb (I) is new. In (I), R = 3-10 C alkyl or 5-8 C cycloalkyl; a = 1 or 2; b = 1 or 2; and a + b = 3. Also claimed are: (i) a process for the prodn. of (I) by reacting an Al hydride (II) with an alcohol of formula ROH (III) in an inert solvent in a mole ratio 1:1 or 1:2; and (ii) a process for the prodn. of optically variable systems by thermal decomposition of (I) in the presence of a 2-dimensional substrate either with or without oxygen, so as to coat the substrate with layers of Al oxide which may contain AlH3 and/or metallic Al.
