ABSTRACT:
The object of the present invention is to provide an image-recording material that may prevent a flocculation of a coating liquid for image-recording layer that contains a water-dispersible emulsion and a water-soluble polymer compound, and that may exhibit an enhanced stability, present an improved film-forming performance, and provide superior surface conditions. In order to achieve the object, an image-recording material according to the present invention is provided, in which the image-recording material comprises a support and at least one image-recording layer on the support, wherein the image-recording layer is formed from a water-dispersible emulsion of which volume-average particle size is 55 nm or more and a water-soluble polymer compound of which weight-average molecular weight (Mw) is 400,000 or less. Preferably, the water-dispersible emulsion is a polyester emulsion. Preferably, the water-soluble polymer compound is polyethyleneoxide.
