Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
In an aqueous autodeposition coating composition having a pH less than 5 comprising: (I) water; (II) a source of hydrogen ion; (III) an oxidizing agent; and (IV) a latex; the improvement consisting of having from 0.1 to 30 weight percent, based on the dry weight of the resinous coating material in said latex, of a water insoluble derivative of glycoluril of the formula: ##STR2## wherein R 1 , R 2 , R 3 and R 4 are each singly alkyl having at least 2 carbon atoms.
Claim 2
Dependent Claim
86 words
In an aqueous autodeposition coating composition having a pH less than 5 comprising: (I) water; (II) a source of hydrogen ion; (III) an oxidizing agent; and (IV) a latex; the improvement consisting of having from 0.1 to 30 weight percent, based on the dry weight of the resinous coating material in said latex, of a water insoluble derivative of glycoluril of the formula: ##STR2## wherein R 1 , R 2 , R 3 and R 4 are each singly alkyl having at least 2 carbon atoms.
Claim 3
Dependent Claim
