Patent ID: 7226715

Claim:
A negative image recording material comprising an aluminum support and an image recording layer disposed on the support, the image recording layer comprising an amide-acid compound, the amide-acid compound containing a carboxyl group and an amide group, wherein said amide-acid compound comprises a polymer having a unit represented by General Formula (4): wherein L 41 , L 42 , L 43 and L 44 may be same or different and each independently represents a hydrogen atom or a hydrocarbon group having 30 or fewer carbon atoms which may have a substituent or a covalent bond; wherein A 41 represents a hydrocarbon group having 30 or fewer carbon atoms which may have a substituent or a covalent bond; and A 42 represents a covalent bond, an ester bond, an amide bond, an ether bond or a hydrocarbon group having 30 or fewer carbon atoms; wherein said amide-acid compound becomes insoluble by a thermal ring-closure reaction between said carboxyl group and said amide group; and wherein the quantity of said amide-acid compound is in a range of from approximately 0.1% by mass to approximately 50% by mass, based on an entire solid content of a coating liquid for the image recording layer.
