Abstract: A decorative laminate comprising a decorative paper sheet and a plurality of resin impregnated sheets wherein color is incorporated into said decorative paper sheet as non-resin impregnated paper chips or one or more colors.

Abstract: A process for making an aqueous pigment dispersion comprising substantially 100 percent .beta.-phase, isometric copper phthalocyanine pigment particles is carried out by activating a pigment crude, followed by fine-milling the activated crude in the presence of an emulsion, the fine-milling taking place in a stirring mill. The resulting pigment slurry is then isolated as an aqueous presscake.

Abstract: The subject invention relates to a process for preparing ferriferrocyanide pigments. The process comprises(a) forming an aqueous reaction mixture comprising(i) a ferrous salt,(ii) a compound selected from the group consisting of sulfuric acid, hydrochloric acid, an inorganic potassium salt, and mixtures thereof, and(iii) an alkali metal ferrocyanide such that the molar ratio of (i) to (ii) to (iii) is about 1:1 to 0.9:1.5 to 1:1;(b) oxidizing the acidic solution by aeration;(c) heating the aerated solution to from 10.degree. C. to 90.degree. C.; and(d) recovering the pigment.

Abstract: The subject invention relates to a process for preparing ferriferrocyanide pigments. The process comprises(1) forming a reaction mixture containing a ferrous salt and an alkali metal ferrocyanide;(2) adding an alkaline compound to said reaction mixture in an amount sufficient to raise the pH to at least 9;(3) oxidizing the basic solution by aeration;(4) heating the solution to a temperature of from 10.degree. C. to 90.degree. C. and(5) recovering the pigment.The advantage of the process is that no significant amount of Berlin White intermediate is formed. Consequently, it is unnecessary to use sulfuric acid to dissolve the Berlin White before oxidation. Moreover, oxidation is achieved by aeration. This is cost effective and reduces the stress to the environment. The resulting pigments are useful in coloring printing ink and carbon paper.
