Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for producing a polymer capable of improving the light fastness of a transferred dye image and a dye fixing element containing the polymer.

[0002]

2. Description of the Related Art A method for forming an image by transferring a dye, for example, a color diffusion transfer method (a photographic technique for obtaining a color image by diffusing and transferring an image-formed dye), a heat development color diffusion transfer method, In a thermal transfer method of a dye (a photographic technique of obtaining an image by heat-transferring a heat transferable dye), a dye fixing element is used to fix the transferred dye. In such a method, an organic dye is usually used as a dye for image formation.
These organic dyes gradually decompose and discolor when exposed to light such as sunlight or fluorescent light, and thus have a problem that the image deteriorates with time.

In order to prevent the fading of this dye, Japanese Patent Publication No.
8-45696 discloses various anti-fading agents. For this purpose, a nitroxyl group is introduced by a polymer substitution reaction. However, in the polymer substitution reaction, it is difficult to control the content of the nitroxyl group, and there is a concern about reproducibility to the effect of preventing discoloration, and thus an improvement in the production method has been desired.

[0004]

Accordingly, an object of the present invention is to provide a method for producing an excellent anti-fading agent for preventing fading of an organic dye due to light, and a method for forming an image by transferring a dye. An object of the present invention is to provide a dye fixing element containing the anti-fading agent.
