6339111, Jan 15, 2002

Filed:

Oct 4, 1993

Appl. No.:

08/131037

Inventors:

John D. Moon - Hastings MN
Louise A. Ziegler - Minneapolis MN
George F. Vesley - Hudson WI
Robert C. Mehner - Oakdale MN
Mark S. Edberg - Centerville MN
Robert D. Anderson - St. Paul MN

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

C08F 246

US Classification:

522 4

Abstract:

Disclosed is a novel, multi-stage irradiation process for the production of an acrylic-based adhesive or pressure-sensitive adhesive tape. The first irradiation step or stage employs electromagnetic radiation at a relatively low average intensity (i. e. , 0. 1 to 20 mW/cm ) and the subsequent step employs electromagnetic radiation at a relatively higher average intensity (i. e. , greater than 20 mW/cm. ) Also disclosed are acrylic-based psa tape materials made by the novel process.

International Classification:

C08F 248

US Classification:

427508, 427510, 427256, 522 2, 522 46, 522 39, 522148, 522149, 522150, 522152, 522153, 522154, 522155, 522156, 522157, 522158, 522159, 522160, 522161, 522162, 264494, 264495

Abstract:

In one aspect the invention provides an energy efficient polymerization method comprising irradiating a polymerizable composition and a photoinitiator with a source of essentially monochromatic radiation where the photoinitiator and the wavelength of the radiation source are selected such that the extinction coefficient of the photoinitiator at the peak wavelength of the source is greater than about 1000 M cm and such that the photoinitiator absorbs at least two percent of the actinic radiation incident on the coating. In another aspect the invention provides energy efficient methods of polymerizing polymerizable compositions and crosslinking crosslinkable compositions by irradiating the respective compositions with a low power source of essentially monochromatic radiation. The low power energy sources have an input power of less than about 10 W/cm. Articles made from the above methods, including polymer films having release coatings, adhesive coatings, hard coatings and the like thereon, also are provided.
