The present invention is related to a printing ink, in particular flexographic printing ink, or an overprint varnish, comprising a nitrated lignin as at least one binder component, to a process for preparing the same as well as to the use of a nitrated lignin as a binder component in a printing ink, in particular a flexographic printing ink, or an overprint varnish.

The current method relates to compositions and methods for inhibiting the deposition of organic contaminants in pulp and papermaking systems. The current method also relates to controlling the deposition of organic contaminants on equipment in the pulp and papermaking systems, which can cause both quality and efficiency problems. In particular it relates to the use of non-sulfonated or slightly sulfonated lignin dispersions and solutions for inhibiting deposition of contaminants in pulp and paper making system.

The invention relates to a method for producing a fiber based product, wherein the method comprises the steps of: a) applying a binder composition over a surface at least one fiber based substrate; b) determining the distribution of the applied binder composition over the en-tire at least one surface of the at least one fiber based substrate; and c) based on the determination in step b) either accepting the treated at least one fiber based substrate for the production of the fiber based product or rejecting the treated at least one fiber based substrate from the production of the fiber based product. The invention further relates to a method for producing a binder composition, to a binder composition and to a fiber based product.

A blended furnish with improved performance characteristics while reducing environmental impact, when applied to a substrate and methods of making and using blended furnish are provided. A composite product using a blended furnish is also provided.

The present disclosure belongs to the technical field of flame-retardant polymers, and in particular, to a composite coating and a preparation method and use thereof. The present disclosure provides a composite coating, including n unit coatings arranged in layers, where n1. Each of the unit coatings includes a first coating and a second coating arranged in layers in sequence. The first coating and the second coating both include a water-soluble polymer compound. The water-soluble polymer compound includes an electropositive water-soluble polymer compound or an electronegative water-soluble polymer compound. The water-soluble polymer compounds in the first coating and the second coating have opposite electrical properties. The first coating and/or the second coating further include/includes M(OH)(OCH.sub.3), where the M includes one or more selected from the group consisting of Co, Ni, Fe, Mg, Al, and Zn. The composite coating provided by the present disclosure has excellent flame retardancy.
