Abstract: A label comprising multiple layers. In one aspect, the label includes an ablation layer and a print layer configured to be below the ablation layer. The ablation layer may have a first color and can comprise at least one infrared (IR) absorbing material and at least one visible light reflecting material. The print layer may have a second color and can comprise at least one IR reflecting and visible light absorbing material. The second color is darker than the first color. The unique chemical composition of the label allows for an ablative substrate with a white top layer and a black bottom layer that results in a strong contrast. In some forms, an adhesive layer in a label might serve as both the print layer and an adhesive layer. In some forms the label can be cut to size with the same laser that engraves print and graphics.

Abstract: A pressure sensitive adhesive (PSA) comprising: (A) 50 to 99 weight percent (wt %) of a partially aromatic polyester comprising at least two hydroxyl groups per polymer chain and having a: (1) Storage modulus of >0.33 Megapascals (MPa) at 23° C., (2) Mn of 20,000 to 200,000 grams per mole (g/mol), and (3) Glass transition (Tg) temperature of ?60° C. to 20° C.; (B) 1 to 40 wt % of at least one of a plasticizer or tackifier; and (C) 0.1 to 10 wt % of a crosslinker with a functionality of >2.5; with the provisos that the PSA has a: (i) Tg of ?60° C. to 10° C.; (ii) Storage modulus of <0.33 MPa at 23° C.; (iii) Rubbery plateau in excess of its Tg; and (iv) Melt flow in excess of 70° C.
