Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
88 words
In a coating composition comprising nitrocellulose, a solvent therefor and a pigmentary flatting agent; the improvement comprising, as said agent, an amorphous alkali metal aluminocarbonate of the following general structure: XM.sub.2 O:Al.sub.2 O.sub.3 :YCO.sub.2 :ZH.sub.2 O wherein M is an alkali metal, X is an integer ranging from about 0.5 to 1.0, Y is an integer ranging from about 0.5 to 2.0, and Z is an integer ranging from about 1 to 4; said aluminocarbonate being present in an amount sufficient to exert flatting properties to said composition.
Claim 2
Dependent Claim
88 words
