Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
113 words
A storage stable photopolymerizable element wound in a roll comprising a supported photopolymerizable composition which contains all components needed for photopolymerization of said composition wherein the composition contains microcapsules on its surface or concentrated near its surface within the composition on a side of the photopolymerizable composition which faces away from the support or which faces toward the support whereby the microcapsules contain a material which is a liquid or a precursor to a liquid whereby said liquid or precursor has the ability to influence the interfacial properties of the photopolymerizable composition or a photopolymerized composition resulting from said photopolymerizable composition and another material and wherein the support comprises a strippable flexible film.
Claim 2
Dependent Claim
113 words
A storage stable photopolymerizable element wound in a roll comprising a supported photopolymerizable composition which contains all components needed for photopolymerization of said composition wherein the composition contains microcapsules on its surface or concentrated near its surface within the composition on a side of the photopolymerizable composition which faces away from the support or which faces toward the support whereby the microcapsules contain a material which is a liquid or a precursor to a liquid whereby said liquid or precursor has the ability to influence the interfacial properties of the photopolymerizable composition or a photopolymerized composition resulting from said photopolymerizable composition and another material and wherein the support comprises a strippable flexible film.
Claim 3
Dependent Claim
21 words
The element of claim 1 wherein the microcapsules are on the side of the composition which faces away from the support.
Claim 4
Dependent Claim
20 words
The element of claim 1 wherein the microcapsules are on the side of the composition which faces toward the support.
Claim 5
Dependent Claim
12 words
The element of claim 1 which does not contain a cover sheet.
Claim 6
Dependent Claim
11 words
The element of claim 1 wherein the microcapsules contain a plasticizer.
Claim 7
Dependent Claim
74 words
A storage stable photopolymerizable element wound in a roll comprising a supported photopolymerizable composition which contains all components needed for photopolymerization of said composition whereby the support comprises a strippable flexible film wherein the composition contains microcapsules on its surface or concentrated near its surface within the composition on a side of the photopolymerizable composition which faces away from the support or which faces toward the support and wherein the microcapsules contain a dye.
Claim 8
Dependent Claim
74 words
A storage stable photopolymerizable element wound in a roll comprising a supported photopolymerizable composition which contains all components needed for photopolymerization of said composition whereby the support comprises a strippable flexible film wherein the composition contains microcapsules on its surface or concentrated near its surface within the composition on a side of the photopolymerizable composition which faces away from the support or which faces toward the support and wherein the microcapsules contain a dye.
Claim 9
Dependent Claim
96 words
A storage stable element wound in a roll comprising a supported photosensitive positive working composition whereby the support comprises a strippable flexible film wherein the composition contains microcapsules on its surface or concentrated near its surface within the composition on a side of the composition which faces away from the support or which faces toward the support whereby the microcapsules contain a material which is a liquid or a precursor to a liquid whereby said liquid or precursor has the ability to influence the interfacial properties of the composition or composition resulting therefrom and another material.
Claim 10
Dependent Claim
96 words
A storage stable element wound in a roll comprising a supported photosensitive positive working composition whereby the support comprises a strippable flexible film wherein the composition contains microcapsules on its surface or concentrated near its surface within the composition on a side of the composition which faces away from the support or which faces toward the support whereby the microcapsules contain a material which is a liquid or a precursor to a liquid whereby said liquid or precursor has the ability to influence the interfacial properties of the composition or composition resulting therefrom and another material.
Claim 11
Independent Claim
126 words
A method comprising applying to a substrate a supported photopolymerizable element containing a photopolymerizable element containing a photopolymerizable layer, imagewise exposing the layer to actinic radiation and removing unexposed areas of the photopolymerizable areas of the photopolymerizable composition whereby the support comprises a strippable flexible film wherein the composition contains microcapsules on its surface or concentrated near its surface within the composition on a side of the photopolymerizable composition which faces away from the support or which faces toward the support whereby the microcapsules contain a material which is a liquid or a precursor to a liquid whereby said liquid or precursor has the ability to influence the interfacial properties of the photopolymerizable composition or a photopolymerized composition resulting from said photopolymerizable composition and another material.
Claim 12
Independent Claim
126 words
A method comprising applying to a substrate a supported photopolymerizable element containing a photopolymerizable element containing a photopolymerizable layer, imagewise exposing the layer to actinic radiation and removing unexposed areas of the photopolymerizable areas of the photopolymerizable composition whereby the support comprises a strippable flexible film wherein the composition contains microcapsules on its surface or concentrated near its surface within the composition on a side of the photopolymerizable composition which faces away from the support or which faces toward the support whereby the microcapsules contain a material which is a liquid or a precursor to a liquid whereby said liquid or precursor has the ability to influence the interfacial properties of the photopolymerizable composition or a photopolymerized composition resulting from said photopolymerizable composition and another material.
Claim 13
Dependent Claim
21 words
The method of claim 8 wherein the microcapsules are on the side of the composition which faces away from the support.
Claim 14
Dependent Claim
27 words
The method of claim 9 wherein the photopolymerizable composition would otherwise adhere to the substrate without insufficient adhesion for further processing without the presence of the microcapsules.
Claim 15
Dependent Claim
20 words
The method of claim 9 wherein the microcapsules are on the side of the composition which faces toward the support.
Claim 16
Dependent Claim
32 words
The element of claim 1 which contains microcapsules on a side of the composition which faces away from the support and on a side of the composition which faces toward the support.
Claim 17
Dependent Claim
32 words
The element of claim 7 which contains microcapsules on a side of the composition which faces away from the support and on a side of the composition which faces toward the support.
Claim 18
Dependent Claim
32 words
The method of claim 8 wherein microcapsules are on a side of the composition which faces away from the support and on a side of the composition which faces toward the support.
