Emulsion coating compositions and process for preparing same

Claim 1

A PROCESS FOR PREPARING A STABILIZED ALKALINE EMULSION COATING COMPOSITION WHICH COMPRISES THE STEPS OF: DISPERSING A WATER-RESISTANT FILMFORMING MATERIAL OF RESINOUS NATURE CAPABLE OF FORMING A FILM WITH A SPECULAR GLOSS OF AT LEAST ABOUT 40 IN WATER IN THE PRESENCE OF A SMALL AMOUNT BY WEIGHT OF THE FILM-FORMING MATERIAL OF AT LEAST ONE SUBSTANTIALLY NEUTRAL REACTION PRODUCT OF A FATTY ACID HAVING BETWEEN 12 AND 20 CARBON ATOMS WITH AN ORGANIC HYDROXY AMINE; INCORPORATING IN THE EMULSION SO FORMED AT LEAST ENOUGH ALKALI-SOLUBLE PROTEINACEOUS COLLOIDALLYDISPERSED MATERIAL TO MAKE THE EMULSION BRUSHABLE BUT NOT MORE THAN ABOUT 16.7% BY WEIGHT OF THE FILM-FORMING MATERIAL; AND INCORPORATING IN THE EMULSION AN ORGANIC HYDROXY AMINE HAVING AN ORIENTABLE MOLECULAR CONFIGURATION OF LYOPHILIC AND HYDROPHILIC GROUPS IN A TOTAL QUANTITY SUFFICIENT (A) TO FORM SAID NEUTRAL REACTION PRODUCT, (B) TO NEUTRALIZE AT LEAST IN PART ANY AVAILABLE ACIDITY OF SAID FILM-FORMING MATERIAL TO A DEGREE SUFFICIENT TO ENABLE THE FREE AMINE REFERRED TO BELOW TO DEVELOP A STABLE ALKALINITY IN SAID EMULSION AT A PH ABOVE ABOUT 8.3, (C) TO SUPPLY ANY QUANTITY OF HYDROXY AMINE NEEDED TO DISPERSE SAID PROTEINACEOUS COLLOIDAL MATERIAL, AND (D) TO SUPPLY A SMALL QUANTITY OF FREE ORIENTABLE HYDROXY AMINE; AT LEAST A PART OF SAID FREE AMINE BEING INTRODUCED IN THE EMULSION AT A TIME NOT LATER THAN THAT AT WHICH THE PROTEINACEOUS COLLOID IS INTRODUCED.
