Abstract
A flexible abrasive article is provided with a first, non-tacky base layer having opposed first and second major surfaces. An ink layer is disposed on the first major surface of the first base layer, while a second, thermoplastic base layer is disposed on the ink layer whereby the ink layer is located between the first and second base layers. Disposed on the second base layer is an abrasive layer such that the second base layer is located between the abrasive layer and the ink layer. Compared with conventional printed flexible adhesive articles, the provided articles improved robustness while avoiding manufacturing difficulties related to flexographic printing onto abrasive coated articles.
Claims15
A flexible abrasive article comprising:
- a first base layer having opposed first and second major surfaces, wherein the first base layer is non-tacky under ambient conditions;
- an ink layer disposed on the first major surface of the first base layer;
- a second base layer disposed on the ink layer whereby the ink layer is located between the first and second base layers and wherein the second base layer comprises a thermoplastic;
- and
- an abrasive layer disposed on the second base layer whereby the second base layer is located between the abrasive layer and the ink layer.
A method of making an abrasive article comprising:
- extrusion coating a first base layer onto a support layer, the first base layer presenting an exposed major surface that is non-tacky at ambient conditions;
- printing an ink layer onto the exposed major surface opposite the support layer;
- extrusion coating a second base layer onto the ink layer to confine the ink layer between the first and second base layers, wherein the second base layer comprises a thermoplastic;
- and
- applying an abrasive coating onto the second base layer.
A method of making an abrasive article comprising:
- extrusion coating a first base layer onto a first support layer, wherein the first base layer is non-tacky at ambient conditions;
- printing an ink layer onto an exposed major surface of the first base layer;
- extrusion coating a second base layer;
- applying an abrasive coating onto the second base layer;
- and
- thermally bonding the second base layer to the ink layer.
