Patent ID: 7348127

Claim:
A topcoat composition, comprising: a polymer comprising: a first monomer having the structure: a second monomer having the structure: where R 1 is selected from the group consisting of a carboxylic acid group having 1 to 4 carbon atoms, R 2 is an alkyl ester group of the form —CO—O—R′ where R′ is an alkyl group having 1 to 4 carbon atoms, and R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are each independently selected from the group consisting of hydrogen, a linear alkyl group having 1-6 carbon atoms, a branched alkyl group having 2-12 carbon atoms, an alicyclic group having 3-8 carbon atoms, an alkyl ester group having 2 to 5 carbon atoms, an alkyl ether group having 2 to 8 carbon atoms, and a fluorinated alcohol group having 1-12 carbon atoms; water; and wherein about 3.6% by volume of said composition consists of concentrated aqueous NH 4 OH.
