Abstract
Novel aluminum compounds with the following empirical formula: AlX3−n(Y)n wherein=0.01 to 2.99, preferably n=2 to 2.75 are described. Each X, individually, can be an inorganic anion such as halides, alkoxides, hydroxide, nitrate, or perchlorate. Each Y, individually, can be an organic anion such as an organic acid containing from one to six carbon atoms, including but not limited to, acetic acid, hydroxy-acetic acid, oxalic acid, succinic acid, citric acid, maleic acid, adipic acid, glutaric acid, and in particular formic acid. Methods to prepare the novel aluminum compounds are also described. Such aluminum compounds are useful in the preparation of decorative paper.
