a copolymer having at least one hydrophilic and at least one hydrophobic ethylenically unsaturated monomer; and
water;
wherein said aqueous polymer composition is a solution or a dispersion having substantially no stabilizing surfactants, and
wherein a film formed from said aqueous polymer composition comprises substantially no crosslinking.
2. The composition of claim 1 wherein said hydrophilic monomer is a cationic, anionic, or amphoteric monomer.
3. The composition of claim 1 wherein said film formed from said polymer composition is insoluble in water.
4. The composition of claim 1 wherein said aqueous polymer composition is clear.
5. A surface-protecting formulation comprising:

6. The composition of claim 5 wherein said film formed from said polymer composition is insoluble in water.
7. The formulation of claim 5 comprising no volatile base.
8. The formulation of claim 5 further comprising sodium hydroxide.
9. The formulation of claim 5 wherein said copolymer further comprises an acid functionality.
10. The formulation of claim 5 wherein said film formed from said copolymer composition is removable using an acid or alkaline cleaning solution.
11. The formulation of claim 5 wherein said copolymer further comprises a star polymer.
12. The formulation of claim 5 wherein said aqueous polymer composition is clear.
13. The formulation of claim 5 wherein said hydrophilic monomer is cationic, anionic or amphoteric.
14. The formulation of claim 5 comprising from 0.00001 to 40 percent by weight of said aqueous polymer composition, based on the surface-protecting formulation.
15. The formulation of claim 5 comprising 0.1 to 20 percent by weight of said copolymer n a solids/solids basis.
16. A process for imparting water resistance to a substrate comprising applying to a substrate the surface-protecting formulation of claim 5 .
17. A coated substrate comprising:
a substrate;
a film on at least one surface of said substrate formed from the aqueous polymer composition of claim.
18. The coated substrate of claim 17 wherein said film is applied to said substrate by spray, brushing, immersion, or flow-through.
19. One or more computer readable media as recited in claim 18 , wherein the indexing structure contains a root and zero or more intervening nodes between the root and the leaf nodes, further comprising computer-executable instructions that, when executed, direct a computing device to authenticity of the root and any intervening nodes on a path from the root to the leaf node associated with the target encrypted block.
