PROBLEM TO BE SOLVED: To make remarkably improvable the image light resistance while keeping excellent color development property and green preservable property, by providing a recording layer containing at least a specified coupler and a specified compound on a supporting body. SOLUTION: The recording layer containing a diazo compound and the coupler microcapsulated by having an alkali soluble resin containing at least one of a styrene unit or an acrylic acid unit as a partition wall, and the compound expressed by the formula is provided on the supporting body. In the formula, R and R' can be the same as or different from each other and represent hydrogen atom or an alkyl group. R1 -R4 can be the same as or different from each other and represent hydrogen atom, an alkyl group, an aryl group or the like. At least one set related to each other by ortho position in R1 -R4 can be bonded with each other to form 5- 6-membered ring. At least one of OR and OR' can be bonded with one of R1 -R4 in ortho position to the OR and OR' to form 5- or 6-membered ring. |
