Abstract
The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrostatographic, including digital, apparatuses. Embodiments pertain to an improved electrostatographic imaging member comprising an interfacial layer further comprising an opaque semi-crystalline polyester resin that is also a hot-melt adhesive to prevent light transmission to the substrate and thus significantly reduce “plywood effect,” a print quality defect.
Claims17
An imaging member comprising
- a substrate;
- a charge blocking layer disposed on the substrate;
- an interfacial layer disposed on the charge blocking layer;
- and
- an imaging layer disposed on the interfacial layer, wherein the interfacial layer comprises a semi-crystalline polyester resin that is a reaction product of adipic acid, ethylene glycol and 1,4-cyclohexanedimethanol, such that light interference from the substrate is substantially reduced;
- wherein the adipic acid is present in an amount of from about 30 to about 70 mole percent, the ethylene glycol is present in an amount of from about 1 to about 20 mole percent, and the 1,4-cyclohexanedimethanol is present in an amount of from about 20 to about 60 mole percent, and the total is 100 percent.
An imaging member comprising
- a substrate;
- a charge blocking layer disposed on the substrate;
- an interfacial layer disposed on the charge blocking layer;
- and
- an imaging layer disposed on the interfacial layer, wherein the interfacial layer comprises a semi-crystalline polyester resin that is a reaction product of adipic acid, ethylene glycol and 1,4-cyclohexanedimethanol dispersed throughout the interfacial layer and the imaging member exhibits from about 0 to about 2 percent light transmission in visible light range;
- wherein the adipic acid is present in an amount of from about 30 to about 70 mole percent, the ethylene glycol is present in an amount of from about 1 to about 20 mole percent, and the 1,4-cyclohexanedimethanol is present in an amount of from about 20 to about 60 mole percent, and the total is 100 percent.
An image forming apparatus for forming images on a recording medium comprising:
- a) an imaging member having a charge retentive-surface for receiving an electrostatic latent image thereon, wherein the imaging member comprises
- a substrate,
- a charge blocking layer disposed on the substrate,
- an interfacial layer disposed on the charge blocking layer, and
- an imaging layer disposed on the interfacial layer, wherein the interfacial layer comprises a semi-crystalline polyester resin that is a reaction product of adipic acid, ethylene glycol and 1,4-cyclohexanedimethanol dispersed throughout the interfacial layer such that light interference from the substrate is substantially reduced;
- wherein the adipic acid is present in an amount of from about 30 to about 70 mole percent, the ethylene glycol is present in an amount of from about 1 to about 20 mole percent, and the 1,4-cyclohexanedimethanol is present in an amount of from about 20 to about 60 mole percent, and the total is 100 percent;
- b) a development component for applying a developer material to the charge-retentive surface to develop the electrostatic latent image to form a developed image on the charge-retentive surface;
- c) a transfer component for transferring the developed image from the charge-retentive surface to a copy substrate;
- and
- d) a fusing component for fusing the developed image to the copy substrate.
