Abstract: The present invention provides: a core-shell latex composition comprising latex particles, each latex particle comprising: (a) a core comprising a (co)polymer comprising (meth)acrylate ester; (b) a shell, surrounding the core, comprising a copolymer, wherein the copolymer comprises: i) a nitrogen-bearing ethynelically-unsaturated free-radically polymerizable monomer; ii) at least one (meth)acrylate ester of about a C1 to about a C14 alcohol; and iii) an optional ethylenically-unsaturated free-radically polymerizable silane monomer; wherein the nitrogen-bearing ethylenically-unsaturated free-radically polymerizable monomer comprises from about 15 to about 60 percent by weight of the shell and further wherein the core comprises from about 40 to about 85 percent of the weight of the total core-shell latex particle. The invention also relates to the use of the core-shell latex composition as a binder or primer for coatings and adhesives.

Abstract: A photographic element comprising a polymeric film base, a silver halide emulsion layer, and an antistatic layer comprising a colloidal vanadium oxide and a vinyl addition polymer dispersion in a dry weight ratio of from 1:30 to 1:500. The antistatic layer may be present as a backing layer on the side of the base opposite the silver halide emulsion layer, as a subbing layer between the base and the emulsion layer in a single or double side coated photographic element, and/or as a subbing layer between the base and a different backing layer. No barrier layer is used over the antistatic layer. Also a process for making an element having antistatic properties.

Abstract: The present invention relates to polymeric microspheres comprised of short-chain diol diacrylate homopolymers or copolymers of diol diacrylates and long-chain acrylate esters, which exhibit excellent antifriction characteristics when applied on the surface of plastic sheets. Treated sheets exhibit a significantly lower coefficient of friction than sheets treated with commercially-available microspheres.
