Modifiers for use in vinyl flooring applications reduce or eliminate the need for traditional, general-purpose plasticizers in applications that require increased hardness or rigidity. High solvating, fast fusing modifiers, such as dibenzoates, added to LVT formulations provide unexpectedly increased flexural strength, hardness, indentation resistance and deflection not heretofore known or recognized in luxury vinyl tile formulations.

An example of a multi-fluid kit for three-dimensional (3D) printing includes an elasticity agent to be applied to at least a portion of a build material composition during 3D printing and a fusing agent to be applied to the at least the portion of the build material composition during 3D printing. The elasticity agent includes a plasticizer having: a formula (I): wherein n is an integer ranging from 3 to 8; or a formula (II): wherein m is an integer ranging from 3 to 8. The fusing agent includes an energy absorber.

Disclosed herein are composite materials comprising amylose, cellulose nanofibres or cellulose nanocrystals, and a plasticiser. The amylose is of high purity, specifically containing little or no amylopectin. The cellulose nanofibres or cellulose nanocrystals act to reinforce the disclosed composite materials. Also disclosed are methods of producing such composite materials, and their use.

The present invention relates to polyvinyl chloride aggregate particles, in which a particle diameter D50 at a cumulative volume percentage of 50 vol % in a volume particle size distribution is 0.5 μm or more and 5.0 μm or less, and a particle diameter D90 at a cumulative volume percentage of 90 vol % in the volume particle size distribution is 8.0 μm or less, and a Na concentration in the polyvinyl chloride aggregate particles is 90 ppm or less. The present invention relates to a composition for a metal can coating material, a composition for a marking film and a method for producing the same, and a coating film that contain the polyvinyl chloride aggregate particles. This provides polyvinyl chloride aggregate particles capable of imparting high transparency and retort resistance to a coating film of a metal can, and/or capable of imparting high transparency and water resistance to a marking film.

Methods for producing a polyamide having an optical absorber pendent from the polyamide's backbone (OAMB-polyamide) may comprise: esterifying a hydroxyl-pendent optical absorber with a halogen-terminal aliphatic acid to yield a halogen-terminal alkyl-optical absorber; and N-alkylating a polyamide with the halogen-terminal alkyl-optical absorber to yield the OAMB-polyamide. Other methods for producing an OAMB-polyamide may comprise: esterifying a carboxyl-pendent optical absorber with a halogen-terminal aliphatic alcohol to yield a halogen-terminal alkyl-optical absorber; and N-alkylating a polyamide with the modified optical absorber to yield a polyamide having the OAMB-polyamide.

Provided are a plasticizer composition and a resin composition, and a preparation method thereof, wherein the present invention may provide a plasticizer, which may improve physical properties, such as plasticizing efficiency, migration, tensile strength, elongation rate, stress resistance, and light resistance, required for a sheet formulation when used as a plasticizer of a resin composition, by improving poor physical properties that have been ascribed to structural limitations, and a resin composition including the plasticizer.
