Abstract

The transfer material has a laminated structure in which a base material sheet, a transparent sheet, and a coloring material-receiving layer are laminated in the stated order, in which: the coloring material-receiving layer contains inorganic fine particles and a water-soluble resin; the transparent sheet contains at least two kinds of emulsions including an emulsion E 1 and an emulsion E 2 ; and the emulsion E 1 has a glass transition temperature Tg 1 of more than 50° C. and less than 90° C., the emulsion E 2 has a glass transition temperature Tg 2 of 90° C. or more and 120° C. or less, and at least the emulsion E 2 remains in a particle state in the transparent sheet.

First claim

What is claimed is:

1 . A transfer material having a laminated structure in which a base material sheet, a transparent sheet, and a coloring material-receiving layer are laminated in the stated order, wherein:
the coloring material-receiving layer contains inorganic fine particles and a water-soluble resin; the transparent sheet contains at least two kinds of emulsions including an emulsion E 1 and an emulsion E 2 ; and the emulsion E 1 has a glass transition temperature Tg 1 of more than 50° C. and less than 90° C., the emulsion E 2 has a glass transition temperature Tg 2 of 90° C. or more and 120° C. or less, and at least the emulsion E 2 remains in a particle state in the transparent sheet.

2 . A transfer material according to claim 1 , wherein a ratio (E 1 /E 2 ) of the emulsion E 1 to the emulsion E 2 satisfies the following expression (1).
3.0≦ E 1/ E 2≦65.0  (1)

3 . A transfer material according to claim 1 , wherein an absolute value (|ΔSP|) of a difference (ΔSP) between a SP value of the emulsion E 1 incorporated into the transparent sheet and a SP value of the water-soluble resin incorporated into the coloring material-receiving layer satisfies the following expression (2).
0≦|ΔSP|≦0.6  (2)

4 . A transfer material according to claim 1 , wherein the emulsion E 1 and the emulsion E 2 respectively comprises a resin each selected from a group consisting of an acrylic resin, a urethane-based resin, a vinyl chloride-based resin, a vinyl acetate-based resin, an ethylene/vinyl acetate-based resin, a polyamide resin, a polyester resin, and a polyolefin resin.

5 . A transfer material according to claim 1 , wherein the emulsion E 1 comprises an acrylic resin and the emulsion E 2 comprises a urethane-based resin.

6 . A recorded matter comprising:
an image support, a coloring material-receiving layer having an image recorded thereon, and a transparent sheet which are laminated, wherein the coloring material-receiving layer and the transparent sheet are transferred from the transfer material of claim 1 .

7 . A recorded matter according to claim 6 , wherein a part of or entirety of the emulsion E 2 in the transparent sheet of the recorded matter forms a film.

8 . A recorded matter according to claim 6 , wherein the image recorded on the coloring material-receiving layer of the transfer material is a reverse image.

9 . A recorded matter according to claim 6 , wherein the image recorded on the coloring material-receiving layer of the transfer material is formed with a pigment ink.

10 . A recorded matter according to claim 6 , wherein the image recorded on the coloring material-receiving layer of the transfer material is formed by an inkjet system.

11 . A method of manufacturing a recorded matter in which an image support, a coloring material-receiving layer having an image recorded thereon, and a transparent sheet are laminated, the method comprising:
a step 1 of recording an image on a coloring material-receiving layer of a transfer material having a laminated structure in which a base material sheet, a transparent sheet, and the coloring material-receiving layer are laminated in the stated order, the coloring material-receiving layer containing inorganic fine particles and a water-soluble resin, the transparent sheet containing at least two kinds of emulsions including an emulsion E 1 and an emulsion E 2 ; a step 2 of thermally pressure-bonding the transfer material, in which the image has been recorded on the coloring material-receiving layer, onto the image support from a side closer to the coloring material-receiving layer; and a step 3 of peeling the base material sheet from the transfer material to obtain the recorded matter in which the coloring material-receiving layer having the image recorded thereon and the transparent sheet are laminated in the stated order.

12 . A method of manufacturing a recorded matter according to claim 11 , wherein:
at a time of the thermal pressure bonding of the step 2, a part of or entirety of the emulsion E 2 in a transfer portion of the transfer material is formed into a film, and at least the emulsion E 2 in a non-transfer portion of the transfer material is remained as particles; and in the step 3, the recorded matter is obtained by peeling the base material sheet from the transfer material while maintaining a state in which the part of or the entirety of the emulsion E 2 in the transfer portion is formed into the film, and the emulsion E 2 in the non-transfer portion is remained as the particles.

13 . An image-recording apparatus, comprising:
a supplying portion configured to feed the transfer material of claim 1 to a conveying path; and a recording portion configured to apply a coloring material to the coloring material-receiving layer of the transfer material, which is fed to the conveying path, to record an image.

14 . An apparatus for manufacturing a recorded matter in which an image support, a coloring material-receiving layer transferred from the transfer material of claim 1 and having an image recorded thereon, and a transparent sheet transferred from the transfer material are laminated, the apparatus comprising:
the image-recording apparatus having a supplying portion configured to feed the transfer material to a conveying path, and a recording portion configured to apply a coloring material to the coloring material-receiving layer of the transfer material, which is fed to the conveying path, to record the image;
an image support-supplying portion configured to feed the image support to the conveying path;
an adhering portion configured to allow the transfer material to adhere to the image support fed to the conveying path; and
a peeling portion configured to peel the base material sheet from the transfer material.
