Abstract: Processes for forming a thermoformed labeled article are described. Labels are attached to a sheet to be thermoformed or to a section thereof. Label attachment can optionally use an adhesive. If the label material is completely or partially compatible with the sheet then the use of adhesive may not be necessary. The labels may also receive various graphics or other designs, such as by printing. After appropriate placement of the label relative to the sheet, the assembly of both sheet and label is thermoformed. After thermoforming, a finished and labeled article is produced. Also described are various labels and label assemblies which are uniquely suited for use in the processes described herein.

Abstract: In general, the invention features a pressure sensitive adhesive that comprises the reaction product of: (a) from about 25 to about 95 parts by weight of at least one acrylic acid ester of a monohydric alcohol whose homopolymer has a Tg less than 0° C., (b) from 0 to about 75 parts by weight of at least one non-polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of no greater than 10.50 and a Tg greater than 15° C.; and (c) from about 5 to about 35 parts by weight of at least one polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of greater than 10.50 and a Tg greater than 15° C. The pressure sensitive adhesives adhere to substrates having a low surface energy and/or high surface energy.

Abstract: Functional mixtures and polymer compositions are provided, each comprising at least one multi-functional Michael acceptor, at least one multi-functional Michael donor, in which at least 20% of either the donor or acceptor or a combination of the donor and acceptor is derived from bio-based materials and at least one catalyst.

Abstract: A pressure sensitive adhesive composition is provided comprised of a cross-linked multifunctional liquid polymer having a Tg<20° C., at least one tackifying resin compatible with the liquid polymer, and at least one additional resin which is either incompatible or at least partially incompatible with the liquid polymer.
