A substrate or coating is provided that includes a lipase with enzymatic activity toward a component of a fingerprint. Also provided is a process for facilitating the removal of fingerprints is provided wherein an inventive substrate or coating including a lipase is capable of enzymatically degrading of one or more components of the fingerprint to facilitate fingerprint removal from the substrate or said coating. Applying heat to the substrate or coating increases the rate of fingerprint removal.

1. A composition for facilitating fingerprint removal comprising: a coating material comprising a solvent-borne two-component polyurethane; anda lipase from Aspergillus niger comprising the sequence of SEQ ID NO: 1, said lipase capable of degrading a fingerprint component, said lipase associated with said coating material so as to be capable of facilitating fingerprint removal when said coating material is contacted by a fingerprint;said composition uniformly coated onto a substrate. 2. The composition of claim 1 wherein said coating comprises an organic crosslinkable polymer resin having a functional group of acetoacetate, acid, amine, carboxyl, epoxy, hydroxyl, isocyanate, silane, vinyl, or combinations thereof. 3. The composition of claim 2 wherein said organic crosslinkable polymer resin comprises aminoplasts, melamine formaldehydes, carbamates, polyurethanes, polyacrylates, epoxies, polycarbonates, alkyds, vinyls, polyamides, polyolefins, phenolic resins, polyesters, polysiloxanes, or combinations thereof. 4. The composition of claim 2 wherein said organic crosslinkable polymer comprises a hydroxyl-functionalized acrylate resin. 5. The composition of claim 1 wherein said lipase is covalently associated with said coating. 6. A composition for facilitating fingerprint removal comprising: a substrate;a lipase from Aspergillus niger comprising the sequence of SEQ ID NO: 1, said lipase capable of degrading a fingerprint component, said lipase associated with said substrate so as to be capable of degrading a fingerprint contacting said substrate; anda fingerprint, said fingerprint contacting said substrate and said lipase. 7. The composition of claim 6 wherein said substrate comprises an organic crosslinkable polymer resin having a functional group of acetoacetate, acid, amine, carboxyl, epoxy, hydroxyl, isocyanate, silane, vinyl, or combinations thereof. 8. The composition of claim 7 wherein said organic crosslinkable polymer resin is aminoplasts, melamine formaldehydes, carbamates, polyurethanes, polyacrylates, epoxies, polycarbonates, alkyds, vinyls, polyamides, polyolefins, phenolic resins, polyesters, polysiloxanes, or combinations thereof. 9. The composition of claim 7 wherein said organic crosslinkable polymer is a hydroxyl-functionalized acrylate resin. 10. The composition of claim 6 wherein said lipase is covalently associated with said substrate. 11. A curable composition for facilitating fingerprint removal comprising: a lipase from Aspergillus niger comprising the sequence of SEQ ID NO: 1; anda solvent-borne two-component polyurethane coating material;said lipase dispersed into said coating by covalent interaction with said coating material so as to be capable of degrading a fingerprint when said coating is contacted by a fingerprint.
