Abstract
Abstract This invention relates to a process for the manufacture of an imaged article which comprises: (a) imagewise irradiating with laser light a material comprising a carrier having on a surface thereof a layer comprising at least one non-photosensitive material, and (b) removing non-irradiated areas of said layer by treating the layer with a developer in which said non-irradiated areas are soluble but in which irradiated areas are insoluble due to modification of said non-photosensitive material by the laser light.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
A process for the manufacture of an imaged article which comprises: (a) imagewise irradiating with laser light a material comprising a carrier having on a surface thereof a layer consisting essentially of at least one polymeric material insensitive to non-coherent light, said layer being water-insoluble and insensitive to low intensity light in the visible, near ultraviolet and near infrared spectral region, and said laser having a minimum power sufficient to form an image in said layer, and (b) removing non-irradiated areas of said layer by treating the layer with a developer in which said non-irradiated areas are soluble but in which irradiated areas are insoluble due to modification of said non-photosensitive material by the laser light.
Claim 2
Dependent Claim
116 words
A process for the manufacture of an imaged article which comprises: (a) imagewise irradiating with laser light a material comprising a carrier having on a surface thereof a layer consisting essentially of at least one polymeric material insensitive to non-coherent light, said layer being water-insoluble and insensitive to low intensity light in the visible, near ultraviolet and near infrared spectral region, and said laser having a minimum power sufficient to form an image in said layer, and (b) removing non-irradiated areas of said layer by treating the layer with a developer in which said non-irradiated areas are soluble but in which irradiated areas are insoluble due to modification of said non-photosensitive material by the laser light.
Claim 3
Dependent Claim
18 words
A process as claimed in claim 1 wherein said laser minimum power is about 1.1 joules/cm 2 .
Claim 4
Dependent Claim
18 words
A process as claimed in claim 1 wherein said polymeric material has a molecular weight above about 150.
Claim 5
Dependent Claim
45 words
A process as claimed in claim 3 wherein the polymeric material is selected from the group consisting of melamine resin, urea resin, alkyd resin, phenolic resin, epoxy resin, maleate resin, acetal resin, polyamide, styrene polymer, acrylic ester polymer, polyester polyvinyl ester or formaldehyde condensation resin.
Claim 6
Dependent Claim
22 words
A process as claimed in claim 1 wherein said layer comprises a polymeric organic substance having a molecular weight above about 150.
Claim 7
Dependent Claim
25 words
A process as claimed in claim 1 wherein the layer comprises at least one dyestuff which absorbs in the emission range of the laser employed.
Claim 8
Dependent Claim
29 words
A process as claimed in claim 6 wherein the dyestuff is present in an amount of from 1 to 80% by weight based on the weight of the layer.
