Abstract

A laminated transfer medium that can be used to make a printed matter or the like which includes a fine relief structure with an improved or even high non-defective rate. The laminated transfer medium can form a transfer laminate which contains a fine relief structure section having a fine relief shape onto a transfer target by using a hot stamp, and characterized in that the laminated transfer medium includes a carrier base, a bonding layer formed on the carrier base, a fine relief structure section having a fine relief shape being disposed on the bonding layer, and an adhesive layer formed on the fine relief structure section, wherein the fine relief structure section is made up of separate discrete pieces positioned to be contained in area to be transferred by using the hot stamp.

First claim

What is claimed is:

1. A laminated transfer medium that forms a transfer laminate which contains a fine relief structure section having a fine relief shape onto a transfer target by using a hot stamp, the laminated transfer medium comprising:
a carrier base;
a bonding layer formed on the carrier base;
the fine relief structure section having the fine relief shape being disposed on the bonding layer;
an adhesive layer formed on the fine relief structure section, wherein the fine relief structure section is made up of separate discrete pieces positioned to be contained in an area to be transferred by using the hot stamp, thereby transferring the fine relief shape; and
a filling section that is formed between the discrete pieces of the fine relief structure section,
wherein the filling section is made of a same material as the adhesive layer, and
wherein the fine relief structure section is made of a resin material containing metal particles.

2. The laminated transfer medium of claim 1 , wherein the adhesive layer is made of a soft resin, and the soft resin has an elongation ratio of 5% or more in a test method under ISO 527 using an ISO test piece (100 μm thickness).

3. The laminated transfer medium of claim 1 , wherein the fine relief structure section is made of a heat resistant resin material having a glass transition temperature of 200° C. or more.

4. The laminated transfer medium of claim 1 , wherein the fine relief structure section is made of a resin material containing an organic nitrogen compound.

5. A printed matter comprising a transfer laminate which contains the fine relief structure section having the fine relief shape, wherein
at least the fine relief structure section in the transfer laminate is formed by being transferred from the laminated transfer medium according to claim 1 onto the transfer target by using a hot stamp, and
the fine relief structure section is contained in the area transferred by using the hot stamp.

6. A laminated transfer medium that forms a transfer laminate which contains a fine relief structure section having a fine relief shape onto a transfer target by using a hot stamp, the laminated transfer medium comprising:
a carrier base;
a bonding layer formed on the carrier base;
the fine relief structure section having the fine relief shape being disposed on the bonding layer;
an adhesive layer formed on the fine relief structure section, wherein the fine relief structure section is made up of separate discrete pieces positioned to be contained in an area to be transferred by using the hot stamp, thereby transferring the fine relief shape; and
a filling section that is formed between the discrete pieces of the fine relief structure section,
wherein the filling section is made of a same material as the adhesive layer, and
wherein the adhesive layer is made of a soft resin, and the soft resin has an elongation ratio of 5% or more in a test method under ISO 527 using an ISO test piece (100 μm thickness).

7. A laminated transfer medium that forms a transfer laminate which contains a fine relief structure section having a fine relief shape onto a transfer target by using a hot stamp, the laminated transfer medium comprising:
a carrier base;
a bonding layer formed on the carrier base;
the fine relief structure section having the fine relief shape being disposed on the bonding layer;
an adhesive layer formed on the fine relief structure section, wherein the fine relief structure section is made up of separate discrete pieces positioned to be contained in an area to be transferred by using the hot stamp, thereby transferring the fine relief shape; and
a filling section that is formed between the discrete pieces of the fine relief structure section,
wherein the filling section is made of a same material as the adhesive layer, and
wherein the fine relief structure section is made of a resin material containing metal oxide particles.
