Imaging transfer system and process for transferring image and non-image areas thereof to a receptor element

A transfer imaging system in which images are formed by image-wise reaction of one or more chromogenic materials and a developer, said system comprising:

• an imaging sheet comprising a first substrate,
• a radiation curable composition which undergoes an increase in viscosity upon exposure to actinic radiation,
• a coating on one surface of said first substrate comprising said chromogenic material and said radiation curable composition,
• said radiation curable composition being encapsulated in rupturable capsules as an internal phase, and
• a developer sheet comprising a second substrate having a front and rear surface,
• a transfer coating on said front surface of the second substrate comprising a material capable of holding developed image and non-image areas that can be transferred to a receptor surface upon the application of heat to the rear surface of the support, said transfer coating layer capable of stripping from said front surface of the support and adhering to said receptor surface by liquefying and releasing from said support when heated and resolidifying within and around fibers of said receptor surface when heat is removed, said resolidified liquid coating seals the transferred image and non-image areas to the receptor surface rendering the transferred image washproof or wash resistant,
• a developer material on said transfer coating capable of reacting with said chromogenic material to form an image on the surface of said second substrate,
• wherein images are formed by image-wise exposing said coating to actinic radiation, and rupturing capsules in the image areas with said coating in facial contact with said developer sheet such that said internal phase is image-wise released from said ruptured capsules and there is image-wise transfer of said chromogenic material to said developer sheet and a patterned image-forming reaction occurs between said chromogenic material and said developer material.

A transfer imaging system in which images are formed by image-wise reaction of one or more chromogenic materials and a developer, said system comprising:

• an imaging sheet comprising a first substrate,
• a chromogenic material,
• a photodepolymerizable composition which undergoes a decrease in viscosity upon exposure to actinic radiation,
• a coating on one surface of said first substrate comprising said chromogenic material and said photodepolymerizable composition,
• said photodepolymerizable composition being encapsulated in rupturable capsules as an internal phase, and
• a developer sheet comprising a second substrate having a front and rear surface,
• a transfer coating on said front surface of the second substrate comprising a material capable of holding developed image and non-image areas that can be transferred to a receptor surface upon the application of heat to the rear surface of the support, said transfer coating layer capable of stripping from said front surface of the support and adhering to said receptor surface by liquefying and releasing from said support when heated and resolidifying within and around fibers of said receptor surface when heat is removed, said resolidified liquid coating seals the transferred image and non-image areas to the receptor surface rendering the transferred image washproof or wash resistant,
• a developer material on said transfer coating capable of reacting with said chromogenic material to form an image on the surface of said second substrate,
• wherein images are formed by image-wise exposing said coating to actinic radiation, and rupturing capsules in the exposed areas with said coating in facial contact with said developer sheet such that said internal phase is image-wise released from said ruptured capsules and there is image-wise transfer of said chromogenic material to said developer sheet and a patterned image-forming reaction occurs between said chromogenic material and said developer material.

• an imaging sheet, a separate image receiving developer sheet having a front and rear surface and having said transfer coating and a dry developer material on said front surface,
