Patent ID: 7951750

Claim:
An image-forming method, comprising the steps of: superposing a heat-sensitive transfer sheet on a heat-sensitive transfer image-receiving sheet so that at least one receptor layer of the heat-sensitive transfer image-receiving sheet described below can be contacted with a thermal transfer layer of the heat-sensitive transfer sheet described below; and providing thermal energy in accordance with image signals given from a thermal head, thereby to form an image; wherein the heat-sensitive transfer sheet comprises: said thermal transfer layer having a yellow colorant layer, a magenta colorant layer and a cyan colorant layer on one surface of a substrate film, and the magenta colorant layer comprises dyes represented by formulae (9), (10) and (11), and the cyan colorant layer comprises dyes represented by formulae (12) and (13); and a heat-resistant sliding layer containing a polymer obtained by reacting a compound having two or more isocyanate groups with a polymer on the other surface of the substrate film; and wherein the heat-sensitive transfer image-receiving sheet comprises: on a support, said at least one receptor layer that is formed by providing at least one kind of latex copolymer of vinyl chloride and an alkyl acrylate; and at least one heat insulation layer that contains non-foaming hollow polymeric particles formed of a polystyrene resin, acryl resin, or styrene/acryl resin in a size of 0.1 to 2 μm, and a water-soluble type resin as a binder: wherein, in formula (9), R 71 and R 73 each independently represent a hydrogen atom or a substituent; R 72 and R 74 each independently represent a substituent; n11 represents an integer of 0 to 4; and n12 represents an integer of 0 to 2; wherein, in formula (10), R 81 represents a hydrogen atom or a substituent; R 82 and R 84 each independently represent a substituent; n13 represents an integer of 0 to 4; and n14 represents an integer of 0 to 2; wherein, in formula (11), R 91 represents a hydrogen atom or a substituent; R 92 represents a substituent; R 93 and R 94 each independently represent a hydrogen atom or a substituent; n15 represents an integer of 0 to 2; one of Z 1 and Z 2 represents ═N— and the other represents ═C(R 95 )—; Z 3 and Z 4 each independently represents ═N— or ═C(R 95 )—; and R 95 represents a hydrogen atom or a substituent wherein, in formula (12), R 101 and R 102 each independently represent a substituent; R 103 and R 104 each independently represent a hydrogen atom or a substituent; and n16 and n17 each independently represent an integer of 0 to 4; and wherein, in formula (13), R 111 and R 113 each independently represent a hydrogen atom or a substituent; R 112 and R 114 each independently represent a substituent; n18 represents an integer of 0 to 4; and n19 represents an integer of 0 to 2.
