## Abstract

A process for the production of a color image is described, in which a photosensitive material that has a temporary support film, a colored photosensitive layer and an adhesion-promoting layer that can be activated by heat is laminated at high temperature and under pressure with an image-receiving material which carries, on a support, a pigment layer containing a white pigment. The photosensitive layer is exposed imagewise and developed to produce an image, the temporary support film is peeled off from the image-receiving material before or after exposure to light and, if required, these steps are repeated with at least one further photosensitive material whose colored layer has another color to produce a multi-colored image. The process gives color images having a smaller dot enlargement compared with a halftone original and is particularly suitable for the color testing of copy for multicolor printing.

## Claims

### Claim 1

An image-receiving material for the production of colored images, comprising a first sheet-like support and a pigment layer which consists essentially of a white pigment and a polymeric binder, wherein said binder is selected from the group consisting of an alkyd resin, a phenol resin, a vinyl polymer, a polyacrylate, and a polymethacrylate, said image-receiving material being prepared by laminating a temporary support film comprising a second sheet-like support and said pigment layer onto said first sheet-like support and then peeling off said second sheet-like support of said temporary support film.

### Claim 2 (depends on 1)

An image-receiving material as claimed in claim 1, wherein said white pigment is an inorganic pigment.

### Claim 3 (depends on 2)

An image-receiving material as claimed in claim 2, wherein the inorganic pigment comprises a water-insoluble oxide, sulfide, sulfate or carbonate of a metal of the 2nd main group IIA or the second subgroup IIB of the Periodic Table.

### Claim 4 (depends on 2)

An image-receiving material as claimed in claim 2 wherein the inorganic pigment comprises a water-insoluble oxide, sulfide, sulfate or carbonate of a metal of the 4th main group IVA or the fourth subgroup IVB of the Periodic Table.

### Claim 5 (depends on 2)

An image-receiving material as claimed in claim 2, wherein the inorganic pigment is selected from the group consisting of CaCO.sub.3, BaSO.sub.4, SrCO.sub.3, MgO, ZnS, ZnO, SiO.sub.2 and TiO.sub.2.

### Claim 6 (depends on 5)

An image-receiving material as claimed in claim 5, wherein the inorganic pigment is TiO.sub.2, having a particle size of from 0.1 to 100 .mu.m.

### Claim 7 (depends on 1)

An image-receiving material as claimed in claim 1, wherein said temporary support film further comprises an adhesion promoting layer applied to said pigment layer.

### Claim 8 (depends on 6)

A temporary support film as claimed in claim 6, wherein said temporary support film further comprises an adhesion promoting layer applied to said pigment layer.
