The present invention provides aqueous matte coating compositions comprising a binder component B) and a polymeric duller component A) composed of particles of one or more multi-stage copolymer or single stage crosslinked (co)polymer, e.g. crosslinked t-butyl (meth)acrylate, the duller component particles A) having an average diameter of 1-20 &#x3bc;m. Components A) and B) are compatible. Preferably, the duller component A) is acrylic; more preferably, components A) and B) are acrylic. The aqueous compositions provide matte coatings having haptic or feel (soft touch) properties, film and appearance properties, including burnish resistance and low color loss.

Aqueous compositions comprising polymeric duller particle

A method of improving an adhesive article, such tape, a label or repositionable paper, containing a paper facestock layer and an adhesive layer is disclosed. The adhesive layer contains a pressure sensitive adhesive and voided latex particles. The incorporation of the voided latex particles into the adhesive layer provides opacity and improves shear strength, without unacceptably compromising the tack and peel adhesion properties of the adhesive layer and without causing wear to processing equipment relative to conventional fillers.

Method of improving an adhesive article

Disclosed herein are high solids thermosetting compositions comprising a solution of a soft, low molecular weight, hydroxy-functional addition polymer resin and a low molecular weight reactive diluent having two or three aliphatic hydroxyl groups per molecule, the weight ratio of resin to diluent being greater than 1, said coating composition when combined with melamine crosslinking agent being of sprayable, roller coatable, or dip coatable viscosity. Cured coatings, coated articles and processes of coating an article are also disclosed.
