Patent ID: 7985535

Claim:
An image-forming method comprising: exposing a negative type image-forming material to light, the negative type image-forming material comprising a support and an image-recording layer comprising (A) a binder polymer comprising at least one group capable of being converted to a sulfonate upon a reaction with an aqueous solution comprising at least one of a sulfite and a bisulfite, (B) a sensitizing dye, (C) a polymerization initiator, and (D) a compound having an ethylenically unsubstituted bond; and removing an unexposed area of the image-recording layer with an aqueous solution comprising at least one of a sulfite and a bisulfite, wherein the group capable of being converted to a sulfonate upon a reaction with an aqueous solution comprising at least one of a sulfite and a bisulfite is a group selected from the group consisting of a bromine atom, an iodine atom, an unsaturated triple bond group, an aldehyde group, a ketone group and a combination thereof.
