摘要:
The present invention relates to a method for negative a positive image, using a negative acting color proofing element comprising, sequentially, a strippable cover sheet; a crosslinked layer containing a polymer having phenolic groups; a color layer, containing a colorant, a polymeric binder, a polymerizable monomer and, optionally, a photoinitiator; a photoadhering layer containing polymerizable groups, and, optionally, a free radical photoinitiator; and a optional thermoplastic adhesive layer. At least one of the color layer and the photoadhering layer containing the photoinitiator. The element is first exposed to actinic radiation and then laminated to a receiver sheet. The composite peeled apart to thereby form a colored negative image on the receiver sheet.

The invention relates to a peel-apart, single sheet color proofing system capable of producing a negative image on a receiver sheet upon exposure to infrared laser radiation and peel development. The invention provides a negative working thermal imageable element for infrared laser imaging having a substantially transparent substrate, an infrared radiation sensitive, crosslinked thermal transfer layer on a surface of the substrate having a substantially uniform admixture of carbon black and a crosslinked polymer, a color layer on the crosslinked thermal transfer layer having a substantially uniform admixture of an organic binder and a colorant, and a thermoplastic adhesive layer on the color layer. The invention also provides a method for producing a negative image and a method for producing a negative working thermal imageable element.
摘要:
A spot gloss film element for color systems which provides a glossy sheen to image-bearing receiver sheets in areas which were exposed to actinic radiation, while the unexposed areas remain partially or completely matte. The film element comprises, sequentially, a strippable, transparent cover sheet; a crosslinked phenolic layer; a gloss layer, which comprises an organic binder, a polymerizable component, a particulate material, and an optional photoinitiator; a photoadhering layer, which comprises a polymerizable component, a binder, and an optional photoinitiator; and a thermoplastic adhesive layer. The spot gloss film is laminated to an image bearing receiver sheet. The gloss layer and the photoadhering layer are exposed to actinic radiation through the transparent cover sheet and crosslinked phenolic layer. After peeling apart the image bearing receiver sheet and the transparent cover sheet, the crosslinked phenolic layer and the unexposed areas of the gloss layer are attached to the cover sheet, while the exposed areas of the gloss layer and the unexposed areas of the photoadhering layer remain attached to the image bearing receiver sheet.
摘要:
A negative-acting color proofing element comprising, sequentially, (i) a strippable, transparent cover sheet; (ii) a crosslinked layer, which comprises a polymer having phenolic groups; (iii) a color layer, which comprises an organic binder, a polymerizable monomer, a colorant, and an optional photoinitiator, (iv) a photoadhering layer, which comprises a polymerizable component having at least one ethylenically unsaturated group; a polymer comprising polyvinyl acetal and polyvinyl alcohol segments, having from about 1 to about 40 weight % polyvinyl alcohol content; and an optional photoinitiator, wherein least one of either the color layer or the photoadhering layer contains a photoinitiator; (v) a thermoplastic adhesive layer; and (vii) a receiver sheet. Preferably the polymerizable component and photoinitiator diffuse into the color layer during assembly of the element. An image is produced by laminating the photosensitive element to a receiver sheet; imagewise exposing the color layer and the photoadhering layer to actinic radiation through the transparent cover and crosslinked phenolic layer; peeling apart the receiver sheet and the transparent cover sheet, leaving exposed areas of the color layer attached to the receiver sheet via the photoadhering layer and adhesive layer and unexposed areas being removed with the cover sheet and the crosslinked phenolic layer, thereby forming a colored negative image on the receiver sheet. Preferably these image producing steps are repeated at least once wherein another photosensitive element having a different colorant is transferred via its photoadhering and adhesive layers to the negative image previously produced on the receiver sheet.

摘要:
A plasma polymer having residual functional (reactive) groups is formed on a substrate, a radiation curable coating composition is applied to the plasma polymer-coated substrate, and the radiation curable composition is radiation cured. The radiation curable composition contains a component which forms a polymer with the reactive groups of the plasma polymer, anchoring the cured composition to the plasma polymer which is anchored to the substrate.
