Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
69 words
A LIQUID COMPOSITION COMPRISING A MIXTURE OF AN IONIC ALUMINUM COMPOUND AND AN IONIC TITANIUM COMPOUND DISSOLVED IN A SOLVENT FOR SAID COMPOUNDS, THE RATIO OF ALUMINUM TITANIUM IN THE COMPOSITION BEING IN THE RANGE OF 20:1 TO 1:20 PARTS BY WEIGHT OF THE METALS AND IN THE COMPOSITION THERE BEING PRESENT PHOSPHATE IONS TO THE EXTENT OF AT LEAST ONE ATOM OF PHOSPHOROUS PER 20 ATOMS OF METAL.
Claim 2
Dependent Claim
69 words
A LIQUID COMPOSITION COMPRISING A MIXTURE OF AN IONIC ALUMINUM COMPOUND AND AN IONIC TITANIUM COMPOUND DISSOLVED IN A SOLVENT FOR SAID COMPOUNDS, THE RATIO OF ALUMINUM TITANIUM IN THE COMPOSITION BEING IN THE RANGE OF 20:1 TO 1:20 PARTS BY WEIGHT OF THE METALS AND IN THE COMPOSITION THERE BEING PRESENT PHOSPHATE IONS TO THE EXTENT OF AT LEAST ONE ATOM OF PHOSPHOROUS PER 20 ATOMS OF METAL.
Claim 3
Dependent Claim
18 words
A composition according to claim 1 in which the ratio of aluminium to titanium is 1:1 to 1:10.
Claim 4
Dependent Claim
13 words
A composition according to claim 1 in which the ratio is substantially 1:5.
Claim 5
Dependent Claim
13 words
A composition according to claim 1 in which the phosphate ions comprise ortho-phosphate.
Claim 6
Dependent Claim
20 words

Claim 8
Dependent Claim
13 words
A solid composition prepared by drying a composition as claimed in claim 1.
Claim 9
Dependent Claim
31 words
A method of making a composition according to claim 1 in which an aluminium compound and a titanium compound are separately dissolved in solvents and the two solutions are then mixed.
