Abstract

Abstract 1. 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: 9
Claim 1
Independent Claim 52 words
A thermal transfer recording image-receiving sheet comprising a support and provided thereon, an image receiving layer comprising 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 to the support.
Claim 2
Dependent Claim 97 words
The sheet of claim 1, wherein the metallic ion-containing compound is a compound represented by the following formula, [M(Q₁) k (Q₂) m (Q₃) n ] p ⁺·p(L⁻) wherein M represents a metallic ion, Q₁, Q₂ and Q₃ 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 3
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 4
Dependent Claim 24 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/m².
Claim 5
Dependent Claim 17 words
The sheet of claim 1, wherein the image receiving layer is composed of a plurality of sublayers.
Claim 6
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 to said support.
Claim 7
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 8
Dependent Claim 123 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 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 metallic ion-containing compound, wherein a concentration of the metallic ion-containing compound is higher at a portion closer to the support.
Claim 9
Dependent Claim 21 words
The method of claim 7, wherein pressure is applied at the same time of said applying heat to the formed image.
