A refinish coating composition is provided comprising: a) at least one refinish coating resin; b) at least one solvent; c) at least one pigment; d) optionally, at least one crosslinking agent; e) at least one cellulose mixed ester having a weight average molecular weight (M) greater than 10,000 and f) at least one low molecular weight cellulose mixed ester. In addition, processes for coating the refinish coating composition on a substrate are also provided.

Refinish coating compositions comprising low molecular weight cellulose mixed esters

A basecoat composition is provided comprising: a) at least one film-forming polymer selected from the group consisting of acrylic polyols and polyester polyols; b) at least one rheological modifier; c) at least one solvent; d) at least one pigment; e) optionally, at least one microgel; f) optionally, at least one crosslinking agent; and g) at least one cellulose mixed ester. A wet-on-wet-on wet process is also provided. The process for coating a substrate comprises: a) applying a primer to said substrate to produce a primed substrate; b) applying a basecoat composition to said primed substrate while said primer is wet to produce a basecoated substrate; and c) applying a clearcoat composition to said basecoated substrate while said basecoat composition is wet and optionally said primer is wet to produce a coated substrate. Coated articles are also provided.

Basecoat coating compositions comprising low molecular weight cellulose mixed esters

Cellulose mixed esters are disclosed having low molecular weights and low degrees of polymerization. These new cellulose mixed esters include cellulose acetate propionate and cellulose acetate butyrate. The esters exhibit solubility in a wide range of organic solvents with minimal viscosity increase, are compatible with a wide variety of resins, and are useful in coatings and inks compositions as binder resins and rheology modifiers.

Low molecular weight cellulose mixed esters and their use as low viscosity binders and modifiers in coating compositions

Modified polyolefins are produced by reacting a functionalized polyolefin with one or more ethylenically unsaturated compounds having a functional group reactive with the functional group on the polyolefin. These modified polyolefins may then polymerize in the presence of a photoinitiator upon exposure to ultraviolet radiation and also have the capability of copolymerizing in the presence of a photoinitiator with other ethylenically unsaturated crosslinking agents upon exposure to ultraviolet radiation. These modified polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines, and therefore may be rendered water-dispersible. The modified polyolefins of the present invention significantly improve the adhesion of paints, inks, and adhesives to various plastic and metal substrates.
