## Abstract

A water-proof fastener tape of an environment-conscious type fabricated using a reduced amount of an organic solvent is provided. The fastener tape includes a base fabric and a water-stop film laminated to at least one surface of the base fabric, the water-stop film includes a surface layer of a polyurethane film and an adhesive layer of a cured product of an aqueous polyurethane adhesive adjacent to the surface layer so that the fastener tape has a laminate structure.

## Claims

### Claim 1

A slide fastener comprising a fastener tape, wherein the fastener tape comprises:
a base fabric; a waterproof surface layer comprising polyurethane; and
a waterproof adhesive layer comprising a cured product of an aqueous polyurethane adhesive, and
wherein the waterproof adhesive layer is between the base fabric and the waterproof surface layer so that the fastener tape has a laminate structure,
wherein the waterproof surface layer comprises a water-soluble organic solvent-borne polyurethane, a water-soluble organic solvent of the water-soluble organic solvent-borne polyurethane comprises one or more selected from the group consisting of glycol ethers, alcohols, terpenes, and pyrrolidones,
wherein the waterproof surface layer comprises a silicone compound,
wherein the waterproof adhesive layer does not comprise a silicone compound, and
wherein the cured product of the aqueous polyurethane adhesive comprises a carboxyl group and/or a neutralized carboxyl group.

### Claim 2 (depends on 1)

The slide fastener according to claim 1, wherein both the waterproof surface layer and the waterproof adhesive layer comprise a polycarbonate polyurethane.

### Claim 3 (depends on 1)

The slide fastener according to claim 1, wherein the content of the silicone compound in the surface layer is in the range of 2% to 25% by mass.

### Claim 4 (depends on 3)

The slide fastener according to claim 3, wherein the content of the silicone compound in the surface layer is in the range of 4% to 15% by mass.

### Claim 5 (depends on 1)

A method for fabricating the fastener tape included in the slide fastener according to claim 1, the method comprising the steps of:
laminating the waterproof surface layer and the base fabric via the aqueous polyurethane adhesive; and
curing the aqueous polyurethane adhesive between the waterproof surface layer and the base fabric.

### Claim 6 (depends on 1)

The slide fastener according to claim 1, wherein the water-soluble organic solvent of the water-soluble organic solvent-borne polyurethane is a mixture of butyl and acetate-glycol ether.
