Assignee:

The Mead Corporation - Dayton OH

International Classification:

G03C 172
G03F 7027

US Classification:

430138

Abstract:

A color image forming process wherein images are formed by reaction of cyan, magenta and yellow color precursors with a developer material, the reaction is image-wise controlled by image-wise exposure of a photosensitive composition encapsulated in pressure rupturable capsules, image-wise exposure of the photosensitive composition and rupture of the capsules releases the color precursor for patterned reaction with the developer material.

International Classification:

G03B 2732
G03B 2752

US Classification:

355 27

Abstract:

An imaging system in which images are formed by image-wise exposing a layer containing a chromogenic material and a photosensitive composition in which at least the photosensitive composition is encapsulated in a lyer of pressure rupturable capsules. Exposure and capsule rupture renders the chromogenic material image-wise accessible to the developer for a patterned image forming reaction.

Assignee:

The Mead Corporation - Dayton OH

International Classification:

G03C 168
G03C 524

US Classification:

430138

Abstract:

This invention relates to image developing apparatus and specifically a developer roll for use in combination with a color producing substrate. In accordance with this invention, a color is formed by the reaction of isolated chromogenic materials. A first chromogenic material is typically a color precursor of the electron donating type and is encapsulated with a photosensitive composition on the surface of an imaging sheet. The second chromogenic material is typically identified as a color developer and is generally of the electron accepting type. In this invention the active coating on the imaging sheet is abraded to rupture the capsules and promote the reaction of the color forming ingredients.

International Classification:

G03C 554
G03C 168
G03C 171

US Classification:

430138

Abstract:

An imaging material of the type in which a radiation sensitive composition is encapsulated in a plurality of microcapsules and exposure controls the release of the internal phase from the microcapsules and mobilization of an image-forming agent in which faster toe speed and higher gamma are obtained by sequestering a predetermined amount of the image-forming agent mobilized upon rupturing the microcapsules.

International Classification:

G03C 140
G03C 100

US Classification:

430138

Abstract:

A process for improving the sensitivity of imaging materials employing an encapsulated radiation sensitive composition including a photoinitiator; wherein the imaging material is subjected to a uniform exposure which does not produce images but sequesters oxygen present in the capsules and converts it to a non-inhibiting form. An imaging material is also disclosed wherein the radiation sensitive composition additionally includes an oxygen sequestering agent.

International Classification:

G03C 140
G03C 100

US Classification:

430138

Abstract:

A transfer imaging system is disclosed wherein images are formed by image-wise exposing a layer comprising a chromogenic material and pressure rupturable capsules containing, as an internal phase, a photosensitive composition. In a preferred embodiment, the chromogenic material is encapsulated with the photosensitive composition. Upon exposure and capsule rupture the chromogenic material is image-wise transferrable to a developer or copy sheet where the chromogenic material reacts with a developer to form an image. Preferred systems are sensitive to U. V. or blue light in the wavelength range of 380 to 480 nm.
