Abstract
Abstract 57 Process for preparation of improved surprint multilayer proof using at least three nonplanar nonsilver photoimaged elements, i.e., negative-working photosensitive element which are laminated sequentially to a support having a permeability to air of less than 0.1 cm 3 /second, a peel adhesion value of at least 250 g/inch (98.49/cm) and a total luminous transmission not in excess od 25%, e.g., oriented polyethylene terephthalate film filled with polypropylene and/or with BaS0 4 or Ti0 2 . The surprints are useful as pre-press proofs.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
In a process of preparing a surprint multicolor proof having at least three nonplanar nonsilver halide photoimaged elements having a color-toned layer, sequentially laminated to a support, said elements in their unexposed state comprising a nontacky photohardenable material with ethylenically unsaturated or benzophenone type groups and a contiguous layer of a nonphotosensitive, tacky organic material wherein each color-toned photoimaged element has been exposed through a different color separation negative and the respective color-toned contiguous layers have been colored in a spectral region corresponding to the color separation used for the exposure, and wherein said support has a peel adhesion value with respect to said contiguous layer of at least 250 grams/inch (98.4 grams/cm) and a total luminous transmission not in excess of 25%, the improvement wherein the support to which the color-toned photoimaged elements are laminated has a permeability to air of less than 0.1 cm 3 /second.
Claim 2
Dependent Claim
148 words
In a process of preparing a surprint multicolor proof having at least three nonplanar nonsilver halide photoimaged elements having a color-toned layer, sequentially laminated to a support, said elements in their unexposed state comprising a nontacky photohardenable material with ethylenically unsaturated or benzophenone type groups and a contiguous layer of a nonphotosensitive, tacky organic material wherein each color-toned photoimaged element has been exposed through a different color separation negative and the respective color-toned contiguous layers have been colored in a spectral region corresponding to the color separation used for the exposure, and wherein said support has a peel adhesion value with respect to said contiguous layer of at least 250 grams/inch (98.4 grams/cm) and a total luminous transmission not in excess of 25%, the improvement wherein the support to which the color-toned photoimaged elements are laminated has a permeability to air of less than 0.1 cm 3 /second.
Claim 3
Dependent Claim
32 words
A process according to claim 1 wherein the support is a paper surface coated with TiO 2 and/or BaSO 4 -filled organic and/or elastomeric binder making said support substantially impermeable to air.
Claim 4
Dependent Claim
25 words
A process according to claim 1 wherein the support is a polymeric film coated with Ti0 2 or TiO 2 /BaSO 4 -filled elastomeric binder.
Claim 5
Dependent Claim
25 words
A process according to claim 1 wherein the support is an oriented polyethylene terephthalate film filled with BaSO 4 , TiO 2 and/or air voids.
Claim 6
Dependent Claim
33 words
A process according to claim 1 wherein the support is paper coated sequentially with corona-treated polyethylene or polypropylene layer and a layer of BaS0 4 and/or Ti0 2 -filled organic and/or elastomeric binder.
Claim 7
Dependent Claim
13 words
A process according to claim 5 wherein the elastomeric binder is chlorosulfonated polyethylene.
Claim 8
Dependent Claim
34 words
A process according to claim 1 wherein the support is paper to which oriented polyethylene terephthalate film filled with BaSO 4 , TiO 2 and/or air voids is laminated with a permanent, nonyellowing adhesive.
Claim 9
Dependent Claim
27 words
A process according to claim 7 wherein the support is paper to which is laminated biaxially oriented polyethylene terephthalate film filled with polypropylene and BaSO 4 .
Claim 10
Dependent Claim
27 words
A process according to claim 7 wherein the support is paper to which is laminated biaxially oriented polyethylene terephthalate film filled with polypropylene and Ti0 2 .
