This microsphere adhesive either contains a (meth)acrylamide comonomer or a polyacrylamide material is post-added to the microsphere adhesive. The adhesive exhibits a lower than expected adhesion to coated papers without sacrificing the adhesion to standard uncoated (bond) papers and preferably, the 90° peel adhesion, as measured on Kromkote® paper (used as an industry standard) is in the range of 20 to 250 grams/inch.

Abstract: A releasable lithographic ink composition comprising (a) air-curable lithographic inks and (b) a release additive. The preferred additives to the air curable inks are combinations of lecithin and components having release functionality that cover a wide range of chemical structures. Functional moieties include silicones, long chain hydrocarbons, and fluorocarbons. In addition, the additive may also contain a moiety which has the ability to interact with the anionic and/or cationic sites of the lecithin. Moieties that can interact with the anionic site are cationic species such as, but not limited to, zinc, sodium, calcium, and quaternary ammonium. Moieties that can interact with the cationic site on the lecithin are anionic species such as, but not limited to, carboxylic acids (and their salts), sulfates, sulfonates, and phosphates.
