Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
A xeroprinting process which comprises (1) providing a xeroprinting master (1) comprising (a) a substrate (22); and (b) a layer of softenable material, (25 comprising a charge transport material (27) capable of transporting charges of one polarity, and migration marking material (26) situated contiguous to the surface of the softenable layer spaced from the substrate, wherein a portion of the migration marking material has migrated through the softenable layer toward the substrate in imagewise fashion; (2) uniformly charging the xeroprinting master to a polarity opposite to the polarity of the charges that the charge transport material in the softenable layer is capable of transporting; (3) uniformly exposing the charged master to activating radiation (31), thereby discharging those areas of the master wherein the migration marking material has migrated toward the substrate and forming an electrostatic latent image; (4) developing the electrostatic latent image, and (5) transferring the developed image to a receiver sheet (45).
Claim 2
Dependent Claim
25 words
A xeroprinting process according to claim 1, wherein the charge transport material is capable of transporting positive charges, and the xeroprinting master is charged negatively.
Claim 3
Dependent Claim
26 words
A xeroprinting process according to claim 2, wherein the charge transport material is of diamine hole-transporting materials, pyrazoline hole-transporting materials, hydrazone hole-transporting materials, or mixtures thereof.
Claim 4
Dependent Claim
25 words
A xeroprinting process according to claim 1, wherein the charge transport material is capable of transporting negative charges, and the xeroprinting master is charged positively.
Claim 5
Dependent Claim
57 words
A xeroprinting process according to claim 4 wherein the charge transport material is of 9-fluorenylidene methane derivative electron-transporting materials; vinyl aromatic electron-transporting materials; electron-transporting polymers of polyesters, polysiloxanes, polyamides, polyurethanes, and epoxies and having aromatic or heterocyclic groups with more than one substituent selected from the group consisting of nitro, sulfonate, carboxyl, and cyano; or mixtures thereof.
Claim 6
Dependent Claim
25 words
A xeroprinting process according to any preceding claim, wherein the xeroprinting master contains a charge-transport layer (9) situated between the substrate and the softenable layer.
Claim 7
Dependent Claim
30 words
A xeroprinting process according to any preceding claim, wherein the xeroprinting master contains a coating layer (15), and the softenable layer is situated between the coating layer and the substrate.
Claim 8
Dependent Claim
25 words
A xeroprinting process according to any preceding claim, wherein the xeroprinting master contains an adhesive layer (5) situated between the substrate and the softenable layer.
Claim 9
Dependent Claim
25 words
A xeroprinting process according to any preceding claim, wherein the xeroprinting master contains a charge-blocking layer (7) situated between the substrate and the softenable layer.
Claim 10
Dependent Claim
36 words
A xeroprinting process according to any preceding claim, wherein the migration marking material is of selenium, alloys of selenium and tellurium, alloys of selenium and arsenic, alloys of selenium, tellurium, and arsenic, phthalocyanines, or mixtures thereof.
