This invention relates to an aqueous coating composition comprising a stable dispersion of resin particles and a coalescing agent wherein the coalescing agent is an alkyl 3-alkoxypropionate having the structure:

Use of alkyl 3-alkoxypropionates as coalescing agents in aqueous coating

Disclosed is a process for making quinones by oxidation of dihydroxyaromatic compounds in the presence of oxygen using supported platinum catalysts.

Oxidation of dihydroxyaromatic compounds to quinones

Provided are novel thermosetting coating compositions comprised of a an epoxy containing acrylic copolymer and 1,3- and/or 1,4-cyclohexanedicarboxylic acid as crosslinking agents. Also provided are shaped or formed articles coated with the cured compositions. The compositions of the invention were found to provide coatings with markedly superior hardness.

Thermosetting powder coating compositions

Disclosed are certain ketoxime-blocked polyisocyanates and polyester compositions containing the ketoxime-blocked polyisocyanates. Also disclosed are thermosetting powder coating compositions comprising one or more polyesters and at least one of the ketoxime-blocked polyisocyanates and articles coated with the powder coating compositions.

Oxime-blocked polyisocyanates and polyester and powder coating

Oxime-blocked polysicyanates and polyester and powder coating

Disclosed are carboxyl polyesters which are useful in the formulation of powder coating compositions. The polyesters are characterized by the presence of terminal carboxycyclohexanecarboxylate groups. Also disclosed is a process for the preparation of the carboxyl polyesters from similar hydroxy polyesters.

Polyesters terminated with carboxycyclohexanecarboxylate groups

Method for the highly selective transesterification of alkyl 3-alkoxypropionates, as well as several novel alkoxypropionate compounds, are provided. Transesterification catalyzed by titanium alkoxides or tin compounds does not catalyze the Michael reaction, and therefore, provide highly selective transesterification reactions of these reactive materials.

Transesterification of alkoxyesters

Disclosed is an improved process for the preparation of alkyl 3-alkoxypropionates by the reaction of a dialkoxymethane with a diketene in the presence of methanedisulfonic acid, methanetrisulfonic acid or mixture thereof.

Process for the preparation of alkyl 3-alkoxypropionates

Disclosed is an improved process for the preparation of alkyl 3-alkoxypropionates containing at least seven carbon atoms by the reaction of dialkoxymethane containing five or more carbon atoms with a ketene in the presence of a catalytic amount of the reaction product of an alkylcarboxylic acid anhydride and concentrated or fuming sulfuric acid.

The present invention relates to a novel coating composition which contains a coalescent. The coating composition comprises a latex of a normally solid organic addition polymer and a coalescing amount of an ether-ester solvent having formula (I) or (II) ##STR1## where R represents hydrogen or an alkyl group of 1 to 4 carbon atoms, R' represents a C.sub.1 -C.sub.4 alkyl group, and n is 1 or 2. Preferred coalescents include 2-ethoxyethyl p-toluate, 2-ethoxyethyl benzoate, 2-(2-ethoxyethoxy)ethyl p-toluate, 2-(2-ethoxyethoxy)ethyl benzoate, 2-propoxyethyl o-toluate, 2-propoxyethyl benzoate, 2-ethoxyethyl o-toluate, 2-methoxy-1-methylethyl benzoate and mixtures thereof. In preferred embodiments, the organic addition polymer comprises an acrylic homopolymer or copolymer. The coating composition preferably comprises about 5-50 parts by weight of the ether-ester solvent per 100 parts of the organic addition polymer.

Coalescent-containing coating composition

The present invention provides an improvement in methods for preparing and processing ethylenically unsaturated aromatic monomer. The improvement comprises employing 3,5-dinitrosalicylic acid or a derivative or isomer thereof as a process inhibitor. The process inhibitor is present in a concentration of about 50 to 3000 ppm, preferably about 250 to 2,000 ppm, and most preferably about 500 to 1,000 ppm.

Process inhibitor for readily polymerizable ethylenically unsaturated

The present invention relates to a novel coating composition which contains a coalescent. The coating composition comprises a latex of a normally solid organic addition polymer and a coalescing amount of an ether-ester solvent having the formula ##STR1## where R represents hydrogen or an alkyl group of 1 to 4 carbon atoms, R' represents a C.sub.1 -C.sub.4 alkyl group, and n is 1 or 2. Preferred coalescents include 2-ethoxyethyl p-toluate, 2-ethoxyethyl benzoate, 2-(2-ethoxyethoxy)ethyl p-toluate, 2-(2-ethoxyethoxy)-ethyl benzoate, 2-propoxyethyl o-toluate, 2-propoxyethyl benzoate, 2-ethoxyethyl o-toluate, and mixtures thereof. In preferred embodiments, the organic addition polymer comprises an acrylic homopolymer or copolymer. The coating composition preferably comprises about 5-50 parts by weight of the ether-ester solvent per 100 parts of the organic addition polymer.

The present invention provides an improvement in methods for preparing and processing ethylenically unsaturated aromatic monomer. The improvement comprises employing 3,5-dinitrosalicylic acid as a process inhibitor. The DNSA is present in a concentration of about 50 to 3000 ppm, preferably about 250 to 2000 ppm, and most preferably about 500 to 1000 ppm.
