PURPOSE: To produce an image by using a composition containing a monomer having high polymerization rate and capable of solidifying at a low conversion by transferring a unexposed part or an insufficiently exposed part of a photopolymerizing composition on an accepting material by heating. CONSTITUTION: At least one kind of the monomer expressed by formula I is incorporated into the photopolymerizing composition. In formula I, (n) expresses a integer of 1-3, (m) expresses a integer of 3-6 when (n) is equal to 1 and (u) is equal to 0 or 1; A has the valency of 3-6 when (n) is equal to 1 and the valency of 2-6 when (n) is 2 or 3, for example, expresses a hydrocarbon residue group of 5-25C which canbe cut by an ether, ester or amide functional group. Thus the image is reproduced conveniently and ecologically by using the highly sensitive photopolymerizable composition. Therefore, the image is reproduced by using an image forming material containing the photopolymerizable composition containing polyfunctional (meth)acrylate monomer high in polymerization velocity and solidified at low conversion rate. |
