Abstract
Abstract The present invention provides an image receiving material comprising on a support an image receiving layer containing physical development nuclei characterised in that said image receiving material contains a nacreous pigment in said image receiving layer and/or in an optional layer between said support and said image receiving layer. Excellent contone images with an antique look can be obtained with such an image receiving material in a silver salt diffusion transfer process.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
45 words
An image receiving material comprising on a support an image receiving layer containing physical development nuclei characterised in that said image receiving material contains a nacreous pigment in said image receiving layer and/or in an optional layer between said support and said image receiving layer.
Claim 2
Dependent Claim
45 words
An image receiving material comprising on a support an image receiving layer containing physical development nuclei characterised in that said image receiving material contains a nacreous pigment in said image receiving layer and/or in an optional layer between said support and said image receiving layer.
Claim 3
Dependent Claim
21 words
An image receiving material according to claim 1 wherein said nacreous pigment is a mica pigment coated with a metal oxide.
Claim 4
Dependent Claim
28 words
An image receiving material according to claim 1 or 2 wherein said nacreous pigment is present in an amount between 0.5 g/m 2 and 10 g/m 2 .
Claim 5
Dependent Claim
38 words

Claim 6
Independent Claim
161 words
A method for obtaining a contone image having an antique look comprising the steps of: image-wise exposing an imaging element containing on a support a photosensitive layer containing a mixture of silver chloride and silver iodide and/or silver bromide dispersed in a hydrophillic colloid binder wherein the silver chloride is present in an amount of at least 90 mole % based on the total mole of silver halide and wherein the weight ratio of hydrophillic colloid to silver halide, expressed as silver nitrate, is between 3:1 and about 10:1 by weight and developing the thus obtained image-wise exposed imaging element in the presence of (a) silver halide solvent(s) and (a) developing agent(s) whilst in contact with an image receiving material comprising on a support an image receiving layer containing physical development nuclei characterised in that said image receiving material contains a nacreous pigment in said image receiving layer and/or in an optional layer between said support and said image receiving layer.
Claim 7
Independent Claim
161 words
A method for obtaining a contone image having an antique look comprising the steps of: image-wise exposing an imaging element containing on a support a photosensitive layer containing a mixture of silver chloride and silver iodide and/or silver bromide dispersed in a hydrophillic colloid binder wherein the silver chloride is present in an amount of at least 90 mole % based on the total mole of silver halide and wherein the weight ratio of hydrophillic colloid to silver halide, expressed as silver nitrate, is between 3:1 and about 10:1 by weight and developing the thus obtained image-wise exposed imaging element in the presence of (a) silver halide solvent(s) and (a) developing agent(s) whilst in contact with an image receiving material comprising on a support an image receiving layer containing physical development nuclei characterised in that said image receiving material contains a nacreous pigment in said image receiving layer and/or in an optional layer between said support and said image receiving layer.
Claim 8
Dependent Claim

Claim 9
Dependent Claim
24 words
A method according to claim 5 wherein said nacreous pigment is present in an amount between 0.5 g/m 2 and 10 g/m 2 .
Claim 10
Dependent Claim
36 words
A method according to claim 5 wherein the surface dimensions of said nacreous pigment are between 5 μm and 200 μm and wherein the thickness of said nacreous pigments is between 0.1 μm and 0.6 μm.
