## Abstract

A bonding method of a resin mold is disclosed comprising a step of butting the end parts of resin molds that is provided with a formed reversal pattern of a fine concave convex pattern that is desired to each other for bonding the resin molds, wherein a detachable resin is filled in a gap of the butted part between the end parts of the resin mold and the end parts of the resin molds are bonded to each other in an integrated manner by the hardening of the detachable resin. Also included is a roll-to-roll continuous mold composition produced thereby.

## Claims

### Claim 1

A bonding method of a resin mold, comprising the step of butting the end parts of resin molds that is provided with a formed reversal pattern of a fine concave convex pattern that is desired to each other for bonding the resin molds, wherein:
a detachable resin is filled in a gap of the butted part between the end parts of the resin molds and the end parts of the resin molds are bonded to each other in an integrated manner by the hardening of the detachable resin.

### Claim 2 (depends on 1)

The bonding method of a resin mold as defined in claim 1, wherein a gap of the butted part of the resin molds is in the range of 0.5 μm to 3 mm.

### Claim 3 (depends on 1)

The bonding method of a resin mold as defined in claim 1, wherein the detachable resin is a silicone resin.

### Claim 4

A roll-to-roll continuous mold composition that is configured to duplicate a resin structure that is provided with a formed fine concave convex pattern that is desired in large quantity on a roll-to-roll basis, comprising:
a plurality of resin molds that is provided with a formed reversal pattern of the fine concave convex pattern that is desired; and
a detachable resin that is filled in a gap between the plurality of resin molds that are arranged in a plane fashion,
wherein the plurality of resin molds are formed in an integrated manner by the hardening of the filled detachable resin.

### Claim 5 (depends on 4)

The roll-to-roll continuous mold composition as defined in claim 4, wherein the resin structure is a replica mold.

### Claim 6 (depends on 5)

The roll-to-roll continuous mold composition as defined in claim 5, wherein the resin molds are arranged on a pressure sensitive adhesive double coated tape.

### Claim 7 (depends on 6)

The roll-to-roll continuous mold composition as defined in claim 6, wherein a location of an end part of the resin mold and a location of an end part of the pressure sensitive adhesive double coated tape are out of alignment in an elongated direction.
