Abstract:

A method of making a repositionable transfer adhesive is provided. The method includes the steps of (a) providing a release liner having opposing first and second surfaces, the first surface having a release value of at least 10 grams per inch, as measured according to the Tape Release Test, lower than the second surface; (b) providing an adhesive composition comprising microsphere adhesive and a binder adhesive; (c) coating the adhesive composition on the first surface of the release liner such that the microspheres protrude from the binder adhesive; (d) drying the adhesive composition to yield a microsphere transfer adhesive; (e) winding the release liner such that the microsphere transfer adhesive is wound inwardly and the second surface of the liner contacts the microspheres; and (f) applying pressure to the second surface of the liner.

International Classification:

B32B005/16

US Classification:

428/523000, 156/307100, 428/515000

Abstract:

A method of making erasable article comprises: providing an electret film having first and second opposed major surfaces; applying a polymerizable precursor composition to at least a portion of the first major surface; polymerizing the polymerizable precursor composition to form a non-tacky crosslinked polymeric layer; and exposing the electret film and non-tacky crosslinked polymeric layer to a direct current corona discharge, wherein the second major surface is free of adhesive material. Erasable articles and kits containing them are also disclosed. Also disclosed are dry erase articles having a first coating layer coated onto a flexible substrate. The first coating composition has a hardness upon curing of greater than about 500 MPa and forms an ink receptive writing surface suitable for receiving dry erase marker ink. The first coating layer has minimal effect on the flexibility of the sheet.

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

B32B 516

US Classification:

428323

Abstract:

A writable matte article comprising a water-absorbing layer coated on a substrate. The water absorbing layer is a unique blend of a crosslinked, water absorbing polymer particle, a water insoluble binder polymer with good adhesion to the film, and optionally, inert organic or inorganic particles that impart a matte finish to the coating. Advantageously, drying times of these inks using the present invention is reduced from about 10 minutes to 10 seconds. Preferred films are polyester and polyolefin-based films.
