Abstract
Abstract A layer transfer material which comprises a temporary support, a light-sensitive resin layer and a separation layer interposed between the temporary support and the light-sensitive resin layer, wherein the separation layer has a low oxygen permeability and a softening point of 80° C. or below and is easily separable from the temporary support and a method of its use.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
A process for forming images using a layer transfer material comprising a light-sensitive resin layer coated on a temporary support, said process comprising the steps of contacting the surface of said light-sensitive resin layer with the surface of a final support at least with heating, removing the temporary support by separation and subsequently subjecting said light-sensitive resin layer to pattern exposure and development to form an image on the final support, wherein a separation layer is interposed between said light-sensitive resin layer and said temporary support of said layer transfer material with the separation layer having a stronger adhesion to said light-sensitive resin layer than to said temporary support, a low oxygen permeability and a softening point of about 80° C. or below.
Claim 2
Dependent Claim
123 words
A process for forming images using a layer transfer material comprising a light-sensitive resin layer coated on a temporary support, said process comprising the steps of contacting the surface of said light-sensitive resin layer with the surface of a final support at least with heating, removing the temporary support by separation and subsequently subjecting said light-sensitive resin layer to pattern exposure and development to form an image on the final support, wherein a separation layer is interposed between said light-sensitive resin layer and said temporary support of said layer transfer material with the separation layer having a stronger adhesion to said light-sensitive resin layer than to said temporary support, a low oxygen permeability and a softening point of about 80° C. or below.
Claim 3
Dependent Claim
21 words
The image forming process according to claim 1, wherein said separation layer has a thickness of from 6 to 30 μm.
Claim 4
Dependent Claim
16 words
The image forming process according to claim 1, wherein said separation layer is soluble in water.
Claim 5
Dependent Claim
38 words
The image forming process according to claim 1, wherein said final support is transparent, said light-sensitive resin layer is colored and said pattern exposure is effected using a masking original having a matrix pattern or a stripe pattern.
Claim 6
Dependent Claim
61 words
A layer transfer material comprising a temporary support having thereon a light-sensitive resin layer and further comprising a separation layer interposed between said light-sensitive resin layer and said temporary support, said separation layer having a stronger adhesion to said light-sensitive resin layer than to said temporary support, a low oxygen permeability and a softening point of about 80° C. or below.
Claim 7
Dependent Claim
61 words
A layer transfer material comprising a temporary support having thereon a light-sensitive resin layer and further comprising a separation layer interposed between said light-sensitive resin layer and said temporary support, said separation layer having a stronger adhesion to said light-sensitive resin layer than to said temporary support, a low oxygen permeability and a softening point of about 80° C. or below.
Claim 8
Dependent Claim
14 words
The material according to claim 5, wherein the separation layer is soluble in water.
