Abstract
Abstract A thermal transfer recording image-receiving sheet is disclosed. The sheet comprises a support and provided thereon, an image receiving layer comprising a metallic ion-containing compound. A concentration of the metallic ion-containing compound at a portion closer to the support is higher than that of the metallic ion-containing compound at a portion farther to the support.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
55 words
A thermal transfer recording image-receiving sheet comprising a support and provided thereon, an image receiving layer comprising a binder and a metallic ion-containing compound, wherein a concentration of the metallic ion-containing compound at a portion closer to the support is higher than that of the metallic ion-containing compound at a portion farther from the support.
Claim 2
Dependent Claim
55 words
A thermal transfer recording image-receiving sheet comprising a support and provided thereon, an image receiving layer comprising a binder and a metallic ion-containing compound, wherein a concentration of the metallic ion-containing compound at a portion closer to the support is higher than that of the metallic ion-containing compound at a portion farther from the support.
Claim 3
Dependent Claim
96 words
The sheet of claim 1, wherein the metallic ion-containing compound is a compound represented by the following formula, [M(Q.sub.1).sub.k (Q.sub.2).sub.m (Q.sub.3).sub.n ].sup.p+.p(L.sup.-1) wherein M represents a metallic ion, Q 1 , Q 2 and Q 3 each represent an coordination compound capable of coordinate-bonding with a metallic ion represented by M, L represents an anion capable of forming a complex, k is an integer of 1, 2 or 3, m is an integer of 1, 2 or 0, n is an integer of 1 or 0, and p is an integer of 1, 2 or 3.
Claim 4
Dependent Claim
23 words
The sheet of claim 2, wherein M in said formula is selected from the group consisting of Ni, Cu, Co, Cr and Zn.
Claim 5
Dependent Claim
26 words
The sheet of claim 1, wherein a total content of the metallic ion-containing compound in the image receiving layer is 0.5 to 20 g/m 2 .
Claim 6
Dependent Claim
17 words
The sheet of claim 1, wherein the image receiving layer is composed of a plurality of sublayers.
Claim 7
Dependent Claim
35 words
The sheet of claim 5, wherein a concentration of the metallic ion-containing compound in an outermost sublayer of the plurality of sublayers is substantially zero, and said outermost sublayer is the farthest from said support.
Claim 8
Dependent Claim
45 words
The sheet of claim 1, wherein the image receiving layer is composed of a first sublayer containing the metallic ion-containing compound and a second sublayer substantially not containing the metallic ion-containing compound, and said second sublayer is closer to said support than said first sublayer.
Claim 9
Dependent Claim
127 words
A thermal transfer recording method comprising the steps of; superposing a thermal transfer recording image-receiving sheet upon a thermal transfer recording ink sheet comprising a support having thereon a heat-diffusible dye-containing ink layer, so that the image receiving layer comes into contact with the ink layer, imagewise applying heat to the superposed materials to transfer the ink layer to the image-receiving sheet and form the image on the image-receiving sheet, applying heat to the formed image, and peeling apart the ink sheet from the superposed materials, said thermal transfer recording image-receiving sheet comprising a support and provided thereon, an image receiving layer comprising a binder and a metallic ion-containing compound, wherein a concentration of the metallic ion-containing compound is higher at a portion closer to the support.
Claim 10
Dependent Claim
127 words
A thermal transfer recording method comprising the steps of; superposing a thermal transfer recording image-receiving sheet upon a thermal transfer recording ink sheet comprising a support having thereon a heat-diffusible dye-containing ink layer, so that the image receiving layer comes into contact with the ink layer, imagewise applying heat to the superposed materials to transfer the ink layer to the image-receiving sheet and form the image on the image-receiving sheet, applying heat to the formed image, and peeling apart the ink sheet from the superposed materials, said thermal transfer recording image-receiving sheet comprising a support and provided thereon, an image receiving layer comprising a binder and a metallic ion-containing compound, wherein a concentration of the metallic ion-containing compound is higher at a portion closer to the support.
Claim 11
Dependent Claim
21 words
The method of claim 8, wherein pressure is applied at the same time of said applying heat to the formed image.
