PURPOSE:To easily obtain a good image and to enable the development by a low alkalinity aq. soln. by using a specific binder contg. an arom. hydroxyl group for a colored recording layer. CONSTITUTION:The colored recording layer provided on a transparent base is capable of forming the colored image when said layer is subjected to image exposing and the development processing using the aq. weak alkaline soln.; in addition, the high-polymer compd. to be used as a binder has the arom. hydroxyl group expressed by formula I. In formula, R1, R2 denote a hydrogen atom., alkyl group, etc.; R3 denotes a hydrogen atom., halogen atom., etc.; R4 denotes a hydrogen atom., phenyl group, etc.; X denotes a nitrogen atom. and divalent org. group which is combined with an arom. hydrocarbon atom.; Y denotes a phenylene group or naphthylene group. The good transferred image is thereby obtd. and the development processing using the aq. weak alkaline soln. is enabled. |
