The invention relates to a security pigment of core-shell particles, comprising a core based on a thermoplastic material, a shell based on a condensation polymer, and an organic or metalorganic feature substance present in dissolved or finely distributed form in the core, wherein the mass fraction of the shell amounts to more than 25%, preferably 50%, particularly more than 100%, in relation to the mass of the core. The invention further relates to a method for producing the core-shell particles and to value documents having the core-shell particles.

Embodiments of the present disclosure generally relate to urea-formaldehyde (UF) resin compositions, methods of making, and uses thereof. In an embodiment, a method of forming a UF resin composition is provided. The method includes heating a first mixture comprising formaldehyde and a first amount of urea, introducing a bio-additive with the first mixture to from a second mixture, and heating the second mixture at a selected temperature while maintaining the second mixture at a selected pH. The method further includes introducing a second amount of urea to the second mixture to form a third mixture, and heating the third mixture to form a first product mixture comprising a UF resin composition. In another embodiment, a UF resin composition is provided. The UF resin composition includes a liquid UF resin and a bio-additive. The UF resin composition can optionally include a rheology- and/or strength-enhancing polymer, a methylated melamine-formaldehyde crosslinker, or both.

Processes for the manufacture of thermally curable resins contain the step of the reaction of a polycondensation-capable phenolic compound and/or of an aminoplastic forming agent with 5-hydroxymethylfurfural (HMF) under conditions leading to formation of polycondensation products. The HMF includes at least one HMF oligomer. Further, thermally curable resins produced by such processes may be used for the manufacture of a wood composite material.

A process for the manufacture of wood composite materials includes the steps of: preparation of a thermally curable resin by reacting a polycondensation-capable phenolic compound and/or an amino plastic forming agent with 5-hydroxymethylfurfural (HMF) under conditions leading to the formation of polycondensation products, bringing the resin into contact with lignocellulose-containing material, and curing the resin with formation of the wood composite material. The 5-hydroxymethylfurfural includes at least one HMF oligomer. Further, wood composite materials are obtainable by the process.

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.

Particulate binder compositions made with amine-aldehyde resins and methods for making same are provided.
