Disclosed is a resinous adhesion promoter comprising (a) a random copolymer having first and second constitutional monomeric units, the first units comprising halogen and/or a pendant organic group having six or more carbon atoms and the second monomeric units comprising an active hydrogen-containing functional group; and (b) one of either (i) a non-reactive adhesion promoter or (ii) a reaction mixture comprising a first component and a second component, at least one of the first and second components having functional groups being reactive with the active hydrogen-containing functional groups of the random copolymer.

Disclosed is a coating composition comprising a resinous binder prepared from a reaction mixture comprising (a) a first component; (b) a second component; and (c) a third component comprising a block copolymer having (i) a first block comprising units having functional groups reactive with at least one of the first and second components and (ii) a second block comprising units having functional groups that promote adhesion to a polymeric substrate, provided that the first component, the second component, and the block copolymer differ from each other. The block copolymer may also be used as an additive in a coating composition.

Coatings for plastic substrates

The present invention is directed to catalytic compositions and to curable compositions containing them. Catalytic compositions of the present invention typically comprise: (i) a reactive compound comprising at least one group selected from acid-functional groups and/or groups that may be converted to acid-functional groups; (ii) a metal compound; and (iii) a compound different from (i) and (ii) that catalyzes an addition reaction between an ethylenically unsaturated compound and a thiol. Curable compositions according to the present invention comprise: (a) a polyene, (b) a polythiol, and (c) the afore-mentioned catalytic composition.

Catalytic compositions and thiolene-based compositions with extended pot life

A method includes (a) contacting at least a portion of a substrate material with a solution comprising a source of copper, wherein the solution is essentially free of a source of a group IIIB metal and a source of a group IVB metal; and (b) after step (a), contacting at least a portion of the substrate with an electrodepositable coating composition comprising (i) a film-forming resin and (ii) a source of yttrium.
