Also claimed are a process for its manufacture, comprising dry-milling, blending and kneading the components, and the use of the pigment concentrates for the preparation of a masterbatch, ink, coating, plastic material, toner or colour filter.
Abstract:
The invention pertains to a novel, simpler dry-milling method for comminuting crude pigments (especially crude phthalocyanines) for use in publication gravure and packaging inks, wherein the crude pigment is dry-milled at relatively low temperature in combination with a resin and a pigment derivative, preferably further together with an extender and optionally an antioxidant. The invention also pertains to the thus obtained, new compositions, which are extraordinarily easily dispersible in aromatic solvents, and their use for the preparation of publication gravure or packaging inks or ink concentrates. Pigment dispersions obtained from the preferred compositions are also claimed.

Abstract:
The invention pertains to a novel, simpler dry-milling method for comminuting crude pigments (especially crude phthalocyanines) for use in offset inks, wherein a high amount of resin is used, at least part of which is a low molecular phenol-modified rosin, an esterified rosin or a hydrocarbon resin of similar properties, preferably together with an antioxidant, and dry-milling is performed at relatively low temperature. The invention also pertains to the thus obtained, new compositions, which are extraordinarily easily dispersible in hydrocarbon solvents, and their use for the preparation of inks or ink concentrates. Pigment dispersions obtained from the preferred compositions are also claimed.

Abstract:
Pigment compositions comprising an organic pigment and a combination of at least two normally water-soluble coloured compounds (dyes) of opposing charge, i.e. of at least one anionic and one cationic dye are provided. The compositions impart improved rheology on non-aqueous pigment based printing inks and paints.
Abstract:
The present invention provides a process for the production of pigmentary copper phthalocyanine in the beta crystalline phase comprising: a) dry or aqueous milling of crude copper phthalocyanine in combination with a natural or chemically modified resin and, optionally, a grinding auxiliary followed by; b) isolation of the milled mass followed by; c) conditioning treatment of the milled mass.
Abstract:
A method of stitching a sewable material, which method includes the steps of: providing a support with a surface; providing a first sheet material with first and second sides; adhering the first side of the first sheet material to the surface of the support; adhering the sewable material to the second side of the first sheet material; and performing a stitching operation on the sewable material with the first sheet adhered to the surface of the support and the sewable material adhered to the first sheet. An adhesive on the first sheet, with a tackiness that increases upon being exposed to a reactant, is used to at least one of a) adhere the first side of the first sheet material to the surface of the support and b) adhere the sewable material to the second side of the first sheet material. The method further includes the step of exposing the adhesive to the reactant before the adhesive is used to at least one of a) adhere the first side of the first sheet material to the surface of the support and b) adhere the sewable material to the second side of the first sheet material.
