Processing tape for optical articles

An optical laminate comprising:

• an optical construction comprising:
• a heat resistant film comprising a first major surface and a second major surface, with an anti-reflective, nanostructured surface coating on the second major surface;
• and
• a tape removably adhered to the anti-reflective, nanostructured surface coating on the second major surface of the optical construction, the tape comprising:
• a thermally stable tape backing with a first major surface and a second major surface;
• and
• a low tack adhesive layer at least partially coated on the first major surface of the tape backing, wherein the low tack adhesive layer comprises a crosslinked, polyester-containing (meth)acrylate-based polymer that is essentially free of volatile components, is unchanged after heat aging of 150° C. for 1 hour under a pressure of 4.31 kiloPascals, wherein the polyester-containing (meth) acrylate-based polymer is prepared from a reaction mixture comprising:
• at least one multifunctional polyester-containing (meth) acrylate;
• at least one polyester-containing (meth) acrylate oligomer;
• and an initiator.

A method of preparing an optical article comprising:

• providing an optical construction comprising:
• a heat resistant film comprising a first major surface and a second major surface, with an anti-reflective, nanostructured surface coating on the second major surface;
• providing a tape, the tape comprising:
• a thermally stable tape backing with a first major surface and a second major surface;
• and
• a low tack adhesive layer at least partially coated on the first major surface of the tape backing, wherein the adhesive layer comprises a crosslinked, polyester-containing (meth)acrylate-based polymer that is essentially free of volatile components, is unchanged after heat aging of 150° C. for 1 hour under a pressure of 4.31 kiloPascals, wherein the polyester-containing (meth) acrylate-based polymer is prepared from a reaction mixture comprising:
• at least one multifunctional polyester-containing (meth) acrylate;
• at least one polyester-containing (meth) acrylate oligomer;
• and an initiator, and is able to removably adhere to the anti-reflective, nanostructured surface of the optical construction;
• adhering the low tack adhesive layer of the tape to the anti-reflective, nanostructured surface coating on the second major surface of the optical construction to form an optical laminate;
• subjecting the optical laminate to a temperature of 150° C. for 1 hour under a pressure of 4.31 kiloPascals;
• and
• cleanly removing the tape from the anti-reflective, nanostructured surface coating on the second major surface of the optical construction.
