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.
Claims6
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.
