Dye image receiving material with polymer particles

A process of forming images comprising steps of

• exposing imagewise a heat-developable color light-sensitive material which comprises a support having thereon a light-sensitive layer containing a binder, light-sensitive silver halide emulsion and dye donating substance capable of forming or releasing a diffusible dye upon heat development and
• superposing a dye image receiving material which comprises a support having thereon a dye receiving layer, over the light-sensitive material during, or after completion of, heat development to transfer dye images to said dye image receiving layer;
• wherein said dye image receiving layer contains a hydrophilic binder and polymer particles, wherein
• said polymer particles comprises a latex comprising polyvinyl chloride or a polyester;
• a weight ratio of said binder to said polymer particles is from 1:1 to 1:10,
• said image receiving layer contains a hardener, and a solvent in an amount of 5 to 50 % by weight to said polymer particles;
• and
• said image receiving layer has not more than 600 % of degree of swell as defined as follows:
• Degree of swell=100.times.(W.sub.A /W.sub.B)
• wherein W.sub.B represents an amount of the hydrophiic binder by weight per m.sup.2 and W.sub.A represents an amount of water by weight per m.sup.2 contained in the image receiving layer when said image receiving material is immersed in water maintained at 30.degree. C.
