## Abstract

The present invention simplifies structures of a transfer material and a printed material both having an image based on a three-dimensional micro-structure, making manufacture of the materials more efficient and reducing prices thereof. An ink receiving layer and an adhesive are provided on a substrate of the transfer material. The ink receiving layer is of an air gap absorption type and has an image based on a three-dimensional micro-structure. Aggregates of the adhesive are discretely arranged on a front surface of the ink receiving layer.

## Claims

### Claim 1

A transfer material, including:
a substrate;
an ink receiving layer provided on the substrate, the ink receiving layer having an image based on a three-dimensional micro-structure; and
an adhesive portion disposed on a first surface of the ink receiving layer that is not contacting the substrate,
wherein the image based on the three-dimensional micro-structure comprises protruding portions that are facing the substrate and is formed on a second surface of the ink receiving layer that is contacting the substrate,
wherein a width of the protruding portions is 10 μm or more and 100 μm or less,
wherein an arithmetic mean height of the protruding portions is 500 nm or more and 10 μm or less,
wherein an arithmetic mean height of an area without the protruding portions on the second surface of the ink receiving layer is 0.5 μm or less,
wherein the arithmetic mean height of the area without the protruding portions is smaller than the arithmetic mean height of the protruding portions,
wherein the ink receiving layer comprises inorganic particulates and a water-soluble resin,
wherein an amount of the water-soluble resin is 3.3 to 20 pts.wt. relative to 100 pts.wt. of the inorganic particulates,
wherein the adhesive portion includes adhesive particles that are aggregated, the adhesive portion being discretely disposed on the first surface of the ink receiving layer, and
wherein the first surface of the ink receiving layer has (i) portions that contact the adhesive portion and (ii) exposed portions that do not contact the adhesive portion.

### Claim 2 (depends on 1)

The transfer material according to claim 1, wherein the substrate has, on a surface thereof contacting the ink receiving layer, a three-dimensional micro-structure including recessed portions opposite to the protruding portions of the ink receiving layer.

### Claim 3 (depends on 1)

The transfer material according to claim 1, wherein the substrate has a protective layer contacting the ink receiving layer.

### Claim 4 (depends on 1)

The transfer material according to claim 1, wherein an area of the exposed portions is 50% or more of a total area of the ink receiving layer.

### Claim 5 (depends on 1)

A manufacturing method for a printed material comprising:
a printing step of printing an image on the transfer material according to claim 1, by applying ink to the transfer material from the adhesive portion side; and
a bonding step of bonding the transfer material with the image printed thereon and an image support, by pressurizing and heating the transfer material and the image support in a superposed state where the adhesive portion contacts to the image support.

### Claim 6 (depends on 5)

The manufacturing method for the printed material according to claim 5, further comprising:
a peel-off step of peeling off the substrate from the transfer material bonded to the image support.
