ABSTRACT:
A 2-diazo-1,2-quinone compound having a substituent group containing an alkyl group which is substituted by at least one fluorine atom is described. This compound has a capacity to change its polarity when exposed to light. The invention also provides an image forming material in which the invention compound is added to at least one of laminated layers. When these laminated layers are exposed to light, the adhesiveness of the compound-containing layer to its adjoining layer is reduced effectively due to the polarity-changing ability of the compound, thus making the easy delamination of the layers possible. This compound is applicable to many instances in which image receiving sheets are used, such as the formation of a multi-color image by a transfer method (a color proof, for example) and the preparation of a printing plate of the delamination development type.
