Color image forming method using silver halide, reducing agent, polymerizable compound and colorant

An image forming method comprising the steps of (A), (1), (2), (3) and (4):

• (A) laminating on an image receiving material a light-sensitive material, which comprises a support, a light-sensitive layer and a polymerizable layer in this order, said light-sensitive layer containing silver halide, said polymerizable layer containing an ethylenically unsaturated polymerizable compound or/and a cross-linkable polymer and a colorant, and a reducing agent being contained in the light-sensitive layer or the polymerizable layer;
• (1) imagewise exposing to light the light-sensitive layer;
• (2) heating the layers at a temperature in the range of 70.degree. to 200.degree. C. for 1 to 180 seconds to harden the ethylenically unsaturated polymerizable compound or/and the cross-linkable polymer within the exposed area or, in the alternative, within the unexposed area;
• (3) peeling the image receiving material from the light-sensitive material to transfer the unhardened area to the image receiving material whereby a color image is formed on the image receiving material;
• and
• (4) repeating the steps (A) and (1) to (3) using light-sensitive materials each having a color different from each other, to form a multicolor image on the image receiving material,
• wherein (A) is prior to (2), (1) is prior to (2), and (2) is prior to (3).
