Abstract

Provided is a transfer material, including: a coloring material-receiving layer; and a base material sheet. The transfer material has a laminated structure in which the base material sheet and the coloring material-receiving layer are sequentially laminated, the coloring material-receiving layer contains at least inorganic fine particles, a water-soluble resin, and a cationic resin having a weight-average molecular weight of 15,000 or less, and a difference SP2 between a SP value of an image support onto which the transfer material is transferred and a SP value of the coloring material-receiving layer to be brought into abutment with the image support satisfies a relationship of 0≤SP2≤1.0.

First claim

What is claimed is:

1. A transfer material, comprising:
a coloring material-receiving layer;
a releasing layer; and
a base material sheet,
wherein the transfer material has a laminated structure in which the base material sheet, the releasing layer, and the coloring material-receiving layer are sequentially laminated,
wherein the coloring material-receiving layer contains at least inorganic fine particles, a water-soluble resin, and a cationic resin having a weight-average molecular weight of 1,000 to 5,000, and
wherein the coloring material-receiving layer is capable of being bonded onto an image support and is separable from the releasing layer.

2. The transfer material according to claim 1 , wherein the cationic resin has a melting point of 60° C. to 160° C.

3. The transfer material according to claim 1 , wherein the cationic resin is a polyallylamine-based resin.

4. The transfer material according to claim 1 , further comprising a transparent sheet,
wherein, in the laminated structure, the base material sheet, the releasing layer, the transparent sheet, and the coloring material-receiving layer are sequentially laminated, and
wherein the transparent sheet and the coloring material-receiving layer are separable from the releasing layer.

5. The transfer material according to claim 4 , wherein the cationic resin has a melting point of 60° C. to 160° C.

6. The transfer material according to claim 4 , wherein the cationic resin is a polyallylamine-based resin.

7. A recorded matter, comprising:
an image support; and
a recording medium having an image recorded thereon,
wherein the image is recorded on the coloring material-receiving layer of the transfer material of claim 4 , and the recording medium is formed by peeling the base material sheet and the releasing layer, and
wherein the recorded matter has a laminated structure in which the image support, the coloring material-receiving layer, and the transparent sheet are sequentially laminated.

8. The recorded matter according to claim 7 , wherein the image is formed with a pigment ink.

9. A method of manufacturing a recorded matter comprising an image support and a recording medium having an image recorded thereon, the method comprising:
recording the image on the coloring material-receiving layer of the transfer material according to claim 4 ;
thermally pressure-bonding the coloring material-receiving layer of the transfer material onto the image support to laminate the coloring material-receiving layer; and
peeling the base material sheet and the releasing layer from the transfer material.

10. The transfer material according to claim 1 , wherein an amount of the water-soluble resin in the coloring material-receiving layer is 3.3 parts by mass to 20 parts by mass with respect to 100 parts by mass of the inorganic fine particles.

11. The transfer material according to claim 4 , wherein an amount of the water-soluble resin in the coloring material-receiving layer is 3.3 parts by mass to 20 parts by mass with respect to 100 parts by mass of the inorganic fine particles.

12. The transfer material according to claim 1 , wherein the image support is formed of at least one of polyvinyl chloride, polyethylene terephthalate glycol-modified, and an acrylic resin.

13. The transfer material according to claim 4 ,
wherein the image support is formed of at least one of polyvinyl chloride, polyethylene terephthalate glycol-modified, and an acrylic resin.

14. A method of manufacturing an image support with a coloring material-receiving layer, the coloring material-receiving layer containing at least inorganic fine particles, a water-soluble resin, and a cationic resin having a weight-average molecular weight of 1,000 to 5,000, the method comprising:
thermally pressure-bonding the coloring material-receiving layer of the transfer material according to claim 1 onto the image support to laminate the coloring material-receiving layer; and
peeling the base material sheet and the releasing layer from the transfer material after the thermally pressure-bonding the coloring material-receiving layer.

15. A method of manufacturing a recorded matter including an image support and a coloring material-receiving layer having an image recorded thereon, the coloring material-receiving layer containing at least inorganic fine particles, a water-soluble resin, and a cationic resin having a weight-average molecular weight of 1,000 to 5,000, the method comprising:
thermally pressure-bonding the coloring material-receiving layer of the transfer material according to claim 1 onto the image support to laminate the coloring material-receiving layer;
peeling the base material sheet and the releasing layer from the transfer material after the thermally pressure-bonding the coloring material-receiving layer; and
recording the image on the coloring material-receiving layer.
