Abstract: Novel red azo pigment--fortified latex compositions for use in printing inks. The novel pigment compositions have superior burn-out resistance and color strength. The novel pigment compositions are made by coupling orthanilic acid derivatives (including optionally, disulfonated amine derivatives) with B-napthal precipitating the metal salts and mixing with fortified latex dispersions. The fortified latex dispersion comprises a dispersed polymer phase in a dissolved polymer phase. The dispersed polymer is preferably a high molecular weight copolymer while the soluble polymer is preferably a low molecular weight acrylic copolymer containing carboxyl group functionality. The novel pigment compositions have superior color strength.

Abstract: A unique opalescent color effect is produced on a substrate material utilizing a multicoat coating system. The primer base coat is a nonmetallic primary color coat having an N-4 to N-8 value on the Munsell color chart. Directly on top of the primer base coat there is applied a transparent interference coat containing a polymeric binder and metal oxide encapsulated mica particles in a pigment to binder ratio of 0.06 to 0.13. On top of the previously applied coats is applied a transparent protective clear coat, the primary base color coat being a high solids content primer layer having good corrosion resistance, good adhesion, etc. The resultant coating in addition to being durable to the elements produces a unique opalescent color effect on the substrate material.

Abstract: A reactive diluent for use in an amine-containing epoxy resin composition. The reactive diluent comprises a soft, blocked isocyanate crosslinking agent. This reactive diluent is incorporated into the resin in addition to the primary crosslinking agent. The use of the reactive diluent eliminates or substantially reduces the need for volatile organic coalescent solvents and produces smooth, durable corrosion resistant coatings.

Abstract: Water based fountain solutions for use in lithographic printing. The fountain solutions contain sufficient hydrogen peroxide to cause lithographic inks to dry more quickly. Typically the fountain solutions will contain about 0.005 wt. % to about 5.0 wt. % of hydrogen peroxide. The hydrogen peroxide containing fountain solutions are typically manufactured as concentrates which are diluted with water at the printing sites to form the proper strength fountain solutions required for printing. The hydrogen peroxide containing fountain solutions are used in conventional lithographic printing processes.

Abstract: A transparent topcoat coating composition is described comprising a thermoplastic or thermosetting resin material containing low pigment to binder ratio of iron oxide encapsulated mica particles.

Abstract: A coating composition is produced particularly adapted for use on the interior of food containers, and specifically metal cans which contain proteinaceous foods. In addition to being nonstaining the particular coating composition is steam resistant and flexible. It is also water dilutable and storage stable. The polymer consists of a reaction product of a plurality of acrylic monomers in the presence of a high molecular weight epoxy resin, a phenolic resin, and a free radical initiator dissolved in a water miscible solvent. The solution is rendered water dilutable by the addition of aqueous amine which neutralizes the carboxyl functionality of the acrylic monomers.

Abstract: A transparent topcoat coating compositions is described comprising a thermosetting resin material containing a pigment composition and a soluble dye. The pigment composition contains about 40 weight percent to about 80 weight percent of iron oxide encapsulated mica particles. The composition also contains 0.5 weight percent to about 82.5 weight percent of a soluble 1:2 chrome or 1:2 cobalt metal organic complex dye. When used in a multi-coat coating process as a base coat overcoated with a transparent topcoat, an article is produced having improved pearlescent color effects, improved depth and clarity, and resistance to fade from ultraviolet light.

Abstract: Oxime blocked polyisocyanate cross-linking agents for use with amine epoxy resin adducts in cathodic electrodeposition processes. The oxime blocking agents are the reaction products of acyclic aliphatic carbonyl-containing compounds having at least 7 carbon atoms and hydroxylamine. The oxime blocked polyisocyanates produce cathodic electrodeposited coatings which are smoother than coatings produced by oxime blocked polyisocyanates known in the art.

Abstract: Improved electrodepositable resin compositions comprising the reaction product of an epoxide, and, the reaction product of a ketone and an alkanolamine. The introduction of a primary monoamine into the epoxide molecule can be simultaneously done, optionally, with chain extension. The resin compositions can also be used as grind resins.

Abstract: Cathodic electrodepositable resin compositions particularly adapted for use as film forming compositions in cathodic electrodeposition processes. The resin is the reaction product of a modified epoxy formed by reacting a polyepoxide with a water soluble or water miscible polyol, an excess of polyamine, and an aliphatic monoepoxide. The resin, when combined with a cross-linking agent and solubilized in an aqueous electrodeposition bath, is capable of depositing high build coatings in a short period of time with a low cross-linking temperature in a cathodic electrodeposition process. The resin compositions are salted with an acid and used as components of aqueous cathodic electrodeposition baths.

Coatings which contain 0.01-5 weight percent mica having up to 60 micrometers maximum platelet length are produced in thicknesses of 0.045-0.076 mm. The coatings are best applied by a conventional turbobell rotary atomizer.

Abstract: A continuous method for producing a dispersion of phthalocyanine blue pigment in an organic solvent is disclosed. The method involves the following two steps:(A) mixing a phthalocyanine crude pigment at about 10 to 50% by weight with from about 5 to 20% by weight of surfactant in a binder containing an organic solvent, and(B) continuously pumping the blend of (A) through at least two shot mills in series in which the shot grinding media range in size from 0.1 to 2.5 mm. diameter and grinding the blend until the particle size of the crude is reduced to where the solvent dispersion has suitable pigment tinctorial strength for use in inks and coatings.The dispersion of blue pigment produced by this method is especially useful in paste inks and organic solvent-based coatings.
