Abstract
Abstract Disclosed is a developer sheet useful in forming reproductions having a glossy finish, or in forming transparencies comprising: a support having a layer of a finely divided, thermoplastic, developer material on the surface thereof, said developer material being capable of reacting with a color precursor to produce a visible image and being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure, and having a surfactant admixed within said layer of developer material to aid in the coalescing of said developer material into a thin film.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
96 words
A developer sheet useful in forming transparencies comprising: a transparent support having a layer of a finely divided, thermoplastic, phenolic resin developer material on the surface thereof, said developer material being capable of reacting with a color precursor to produce a visible image and being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure, and having a dialkyl ester of sodium sulfosuccinic acid and a glycol admixed within said layer of developer material to aid in the coalescing of said developer material into a thin film.
Claim 2
Dependent Claim
96 words
A developer sheet useful in forming transparencies comprising: a transparent support having a layer of a finely divided, thermoplastic, phenolic resin developer material on the surface thereof, said developer material being capable of reacting with a color precursor to produce a visible image and being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure, and having a dialkyl ester of sodium sulfosuccinic acid and a glycol admixed within said layer of developer material to aid in the coalescing of said developer material into a thin film.
Claim 3
Dependent Claim
40 words
The developer sheet according to claim 1 wherein said developer material is selected from the group consisting of phenol-formaldehyde resins, a metallated condensation product of a phenol and formaldehyde, and the product of oxidative coupling of a phenol or bisphenol.
Claim 4
Dependent Claim
18 words
The developer sheet according to claim 2, wherein said dialkyl ester is di-octyl ester of sodium sulfosuccinic acid.
Claim 5
Dependent Claim
29 words
The developer sheet according to claim 3 wherein the gloss temperature of the developer material is about 130° C. when said developer material is heated for about 60 seconds.
Claim 6
Dependent Claim
14 words
The developer sheet according to claim 4 wherein said transparent film is polyethylene terephthalate.
Claim 7
Dependent Claim
25 words
The developer sheet of claim 5 wherein said glycol is selected from the group consisting of polyethylene glycol, polypropylene glycol, ethylene glycol, and diethylene glycol.
Claim 8
Dependent Claim
12 words
The developer sheet of claim 6 wherein said glycol is polyethylene glycol.
Claim 9
Independent Claim
132 words
A system for forming images comprising a developer sheet comprising a transparent support having a layer of a finely divided, thermoplastic, phenolic developer material on the surface thereof, said developer material being capable of reacting with a color precursor to produce a visible image and being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure, and having a dialkyl ester of sodium sulfosuccinic acid and a glycol admixed within said layer of developer material to aid in the coalescing of said developer material into a thin film; and a donor sheet including a support having a layer of microcapsules on the surface thereof, said microcapsules having a color precursor associated therewith capable of reacting with said developer material to form an image.
Claim 10
Independent Claim
132 words
A system for forming images comprising a developer sheet comprising a transparent support having a layer of a finely divided, thermoplastic, phenolic developer material on the surface thereof, said developer material being capable of reacting with a color precursor to produce a visible image and being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure, and having a dialkyl ester of sodium sulfosuccinic acid and a glycol admixed within said layer of developer material to aid in the coalescing of said developer material into a thin film; and a donor sheet including a support having a layer of microcapsules on the surface thereof, said microcapsules having a color precursor associated therewith capable of reacting with said developer material to form an image.
Claim 11
Dependent Claim
18 words
The system according to claim 8 wherein said microcapsules contain a photohardenable composition associated with said color precursor.
Claim 12
Dependent Claim
111 words
A process for forming transparencies comprising the steps of: image-wise reacting a color precursor with a reactive surface of a developer sheet comprising a transparent support having a layer of finely divided, thermoplastic, phenolic developer material on the surface thereof to produce an image, said developer material being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure, said support having a dialkyl ester of sodium sulfosuccinic acid and a glycol admixed within said layer of developer material; and coalescing said developer material by applying heat and/or pressure to said developer material, said surfactant aiding in the coalescing of said developer material.
Claim 13
Dependent Claim
111 words
A process for forming transparencies comprising the steps of: image-wise reacting a color precursor with a reactive surface of a developer sheet comprising a transparent support having a layer of finely divided, thermoplastic, phenolic developer material on the surface thereof to produce an image, said developer material being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure, said support having a dialkyl ester of sodium sulfosuccinic acid and a glycol admixed within said layer of developer material; and coalescing said developer material by applying heat and/or pressure to said developer material, said surfactant aiding in the coalescing of said developer material.
Claim 14
Dependent Claim
93 words
The process according to claim 10 wherein said step of image-wise reacting said color precursor includes the steps of image-wise exposing an imaging sheet including a support having a layer of microcapsules on the surface thereof to actinic radiation, said microcapsules including a photohardenable photosensitive composition as the internal phase and having a chromogenic material associated therewith; assembling said image-wise exposed imaging sheet with said developer sheet; and subjecting said imaging sheet to a uniform rupturing force such that said microcapsules rupture and release said internal phase in accordance with said image-wise exposure.
Claim 15
Dependent Claim
39 words
The process according to claim 10 wherein said developer material is selected from the group consisting of phenol-formaldehyde resins, a metallated condensation product of a phenol and formaldehyde, and the product of oxidative coupling of a phenol or bisphenol.
