Abstract

A photosensitive transfer material comprises a temporary substrate having provided thereon an alkali-soluble thermoplastic resin layer, an intermediate layer, and a photosensitive resin layer in this order, the interlaminar adhesion in the transfer material being the smallest at the interface between the thermoplastic resin layer and the temporary substrate. The photosensitive resin layer can be transferred to a permanent substrate without involving failure due to fine dust, air bubbles or unevenness of the permanent substrate. An image can be formed with the transfer material by adhering the transfer material to a permanent substrate at least under heat and, after stripping the temporary substrate, imagewise exposing the photosensitive resin layer to light, and processing the transferred layers to develop the photosensitive resin layer. If the thermoplastic resin layer and the intermediate layer are first removed with a processing method with which the photosensitive resin layer is not substantially developed and then the photosensitive resin layer is developed using a processing solution other than used for revmoving the thermoplastic resin layer and the intermediate layer, excessive fatigue of the developing solution for the photosensitive resin layer and unevenness of development can be prevented.

Claims

1. A method for forming an image comprising the steps of:

adhering a photosensitive resin layer of a photosensitive transfer material comprising a temporary substrate having provided thereon an alkali-soluble thermoplastic resin layer, an intermediate layer, and a photosensitive resin layer in this order, the interlaminar adhesion in said transfer material being the smallest at the interface between said thermoplastic resin layer and said temporary substrate, to a permanent substrate under at least heat,

stripping said temporary substrate from said thermoplastic resin layer,

imagewise exposing the photosensitive resin layer to light, and

processing the photosensitive transfer material to develop the photosensitive resin layer to form an image on said permanent substrate.

2. A method for forming an image as claimed in claim 1, wherein said steps are repeated by using at least two photosensitive transfer materials differing in the color of the photosensitive resin layers thereof to form multicolor image on the parmanent substrate.

3. A method for forming an image as claimed in claim 1, wherein the processing step comprises i) removing the alkali-soluble thermoplastic resin layer and the intermediate layer with a processing solution which does not substantially develop the photosensitive resin layer and ii) developing the photosensitive resin layer using a developing solution which is different from the processing solution used in i).
