Cleanable articles having overcoats with hydrophilic front surfaces and which are siloxane-bonded to an underlying body member. Also, methods of making and using such articles.

Cleanable articles and methods for making and using same

A communication article and system comprising a writing member having a dry erasable front surface and a projection member is disclosed. The projection member includes an asymmetric optical diffuser that scatters light in a first direction with a first viewing angle A, and in a second direction orthogonal to the first direction with a second viewing angle A. The ratio A/Ais at least about 2.

Dry erasable projection article and system

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.

Method of making a microsphere transfer adhesive

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.
