Abstract

The present invention relates to a pressure sensitive label for use in a cold transfer process that can be used for garment identification and labeling. The pressure sensitive label can be applied on textile surface or any other surfaces for which heat transfer is unfavorable or unavailable. The pressure sensitive label can remain on the substrate to which it is attached through repeated washing and drying cycles.

First claim

What is claimed is:

1. A cold transfer pressure sensitive label for labeling a fabric material, the pressure sensitive label comprising:
a pressure sensitive adhesive with a first surface and a second surface and a release liner is disposed on the second surface of the pressure sensitive adhesive the pressure sensitive adhesive is one of a solvent-based polymer or an emulsion-based polymer, and includes between 5% to 50% by weight of a hydrogenated rosin ester based tackifier and,
at least one printable film layer having a design and constructed out of soft and stretchable material disposed on the first surface of the pressure sensitive adhesive, the at least one printable film layer configured to stretch to the extent of the fabric material stretching and the pressure sensitive adhesive is in registration with the design;
at least one ink layer disposed on the printable film layer;
a removable support having an upper surface and a lower surface, and the lower surface is disposed on the at least one ink layer wherein the pressure sensitive adhesive has a wet adhesion greater than about 10 N/in such that a non-silicone pressure sensitive adhesive release material is coated over the upper surface of the removable support wherein the removable support with the release material is removed when the cold transfer pressure sensitive label is attached to a substrate such that only the at least one ink layer is attached to the substrate through the pressure sensitive adhesive and the surface energy of the lower surface of the removable support on the at least one ink layer is between 20 to 35 mN/m, and
the label is transferable to the fabric material without heat and
the pressure sensitive label is capable of remaining on the substrate through repeated washing and drying cycles.

2. The pressure sensitive label of claim 1 ,
wherein the ink layer is selected from a group consisting of digital inks, dye inks, pigment inks, wax inks, UV inks, liquid toner inks, ink jet inks, laser toners, marker inks, analog inks, flexo inks, gravure inks, liquid inks, solid inks, thermography powders, screen printing inks, and combinations thereof.

3. The pressure sensitive label of claim 1 , wherein the pressure sensitive adhesive is digital or analog printable.

4. The pressure sensitive label of claim 1 , wherein the pressure sensitive adhesive label is self wound or stacked with the pressure sensitive adhesive in contact with the upper surface of the removable support.

5. The pressure sensitive label of claim 1 , wherein the pressure sensitive adhesive is cross-linked.

6. The pressure sensitive label of claim 1 , wherein the printable film layer is selected from the group consisting of polyurethane, EVA, PET, fabric, synthetic leather, suede, foam, specialty paper, polypropylene, polyethylene, polyolefin, inkjet printable media, toner printable media, pvc, non-pvc film, bamboo textiles, biodegradable polymer, PLA, woven, and nonwoven materials.

7. The pressure sensitive label of claim 1 , further comprising a functional layer selected from the group consisting of RFID components, barcodes, identification components, indication components, sensing components, marking components, tracking components, temperature sensing components, and authentication components.

8. A cold transfer pressure sensitive label for labeling a substrate, the pressure sensitive label comprising:
a pressure sensitive adhesive layer, the pressure sensitive adhesive layer is one of a solvent-based polymer or an emulsion-based polymer, and includes between 5% to 50% by weight of a hydrogenated rosin ester based tackifier;
at least one elastomeric ink layer disposed on the pressure sensitive adhesive layer, the elastomeric ink comprises a polyacrylate and the at least one elastomeric ink layer is made up of multiple layers;
a removable support disposed on the least one elastomeric ink layer on a surface opposite the pressure sensitive adhesive layer wherein the removable support has an upper surface and a lower surface such that the surface energy of the lower surface of the removable support on the at least one ink layer is between 20 to 35 mN/m and wherein a non-silicone pressure sensitive adhesive release material is coated over the upper surface of the removable support; and
wherein the pressure sensitive adhesive is one of a solvent-based polymer, a tackified emulsion polymer, or UV curable and has a wet adhesion greater than about 10 N/in and the label is transferable to the substrate without heat and the substrate and the removable support is removed when the cold transfer pressure sensitive label is attached to a substrate such that only the at least one ink layer is attached to the substrate through the pressure sensitive adhesive, and an RFID
tag is attached to the substrate through the adhesive layer and
the pressure sensitive label is capable of remaining on the substrate through repeated washing and drying cycles.

9. The pressure sensitive label of claim 8 , further comprising a release liner disposed on the pressure sensitive adhesive layer.
