Substrate coated with mixed resin primer coat comprising a block copolymer

A coated article of manufacture comprising a substrate surface bearing a primer coat and a top coat, said primer coat being adherent both to the substrate and the top coating, wherein said primer coat contains no oil component and comprises:

• a. a selectively hydrogenated block copolymer having at least two polymer blocks A and at least one polymer block B, each block A being a non-elastomeric polymer block of a monoalkenyl arene having an average molecular weight between about 2,000 and about 125,000 and each block B being a hydrogenated polymer block of a conjugated diene wherein at least 80% of the double bonds have been reduced by hydrogenation and wherein block B has an average molecular weight between about 10,000 and 250,000;
• b. 50-150 parts by weight per 100 parts by weight of said block copolymer of a first resin being compatible with the blocks A in the proportions employed, wherein said first resin is selected from the group consisting of coumarone-indene resins, olefinic hydrocarbon resins, rosin methyl ester, vinyl toluene/alphamethyl styrene copolymer, alphamethyl styrene copolymer, polyindene resin, and poly(methyl indene)resin;
• and
• c. 50-150 parts by weight per 100 parts by weight of said block copolymer of a halogen-free carboxylated second resin, having an acid number between 15 and 60, said second resin comprising the reaction product of a component C of the group consisting of conjugated dienes, rosin, unsaturated fatty acids, and mixtures thereof with a component D of the group consisting of unsaturated polycarboxylic acids, and anhydrides or esters thereof, said resin being at least partially compatible with blocks A and largely incompatible with hydrogenated diene block B.
