A color-changing sheet according to an embodiment of the present invention may include a base layer having a brightness (L value) of less than 40 and a color layer positioned on at least one surface of the base layer, containing a color dye or a pigment, and having a transmittance of to 90%, wherein a thickness ratio of the base layer to the color layer is 0.1 to 10, and may realize color change without adding additional particles.

Binders, methods for making same, and methods for making composite lignocellulose products therefrom. The binder can include about 30 wt % to about 40 wt % of solids that include a urea-modified aldehyde-based resin; about 0.1 wt % to about 3 wt % of solids that include an isocyanate-based resin; about 0.1 wt % to about 12 wt % of an extender; and about 50 wt % to about 62 wt % of water, where all weight percent values are based on a total weight of the binder. The binder can have a sodium hydroxide equivalent weight alkalinity of about 3 wt % to about 9 wt %.

A resin composition, a formed article, and, an electromagnetic wave absorber, may each have large electromagnetic wave absorbance. The resin composition may contain: a thermoplastic resin; and an electro-conductive substance, the resin composition, when formed to a 2 mm thick test specimen and a cross section thereof is observed under a digital microscope, giving an aggregate attributable to the electro-conductive substance, with an area percentage of the aggregate, having an equivalent circle diameter of 30 .Math.m or larger, of 0.80% or smaller.

Novel articles of manufacture are described based on a combination of an adjunct material and microcapsules made by an improved process. The improved microcapsules are chitosan urea and encapsulate a benefit agent. The process comprises combining an adjunct material formed of microcapsules formed by a water phase comprising hydrolyzing chitosan in an acidic medium at a pH of 6.5 or less for an extended period and combining with a polyisocyanate. The reaction product of the hydrolyzed chitosan and polyisocyanate yields a microcapsule having improved release characteristics, with enhanced degradation characteristics in OECD test method 301B.

A polymer composition may include a crosslinked polymeric additive composition that includes a matrix polymer comprising a polyolefin, and one or more polymer particles dispersed in the polymer matrix, wherein the one or more polymer particles comprise a polar polymer selectively crosslinked with a crosslinking agent; and a secondary polymer composition.

This invention relates to a multilayer biodegradable film which is particularly suitable for the manufacture of packaging and is also characterised by appreciable optical transparency properties in addition to high level mechanical properties.

An extrusion composition containing at least one resin selected from the group consisting of polypropylene homopolymers, polypropylene random copolymers, and polypropylene impact copolymers. The extrusion composition also contains at least one phosphate ester-based nucleating agent provided in the composition at a use level of between about 0.01 and 0.15 parts by weight, in relation to 100 parts by weight of the resin. The extrusion composition also contains at least one co-additive selected from the group of poly(ethylene glycol) and copolymers containing segments of ethylene oxide, where the co-additive has a number average molecular weight of about 300 or more, and where the use level of the co-additive is about 0.005 parts by weight or more. The extrusion composition further contains a metal salt of a fatty acid at a use level of between about 0.01 and 0.15 parts by weight.

An amorphous or semi-crystalline polymer/aPHA composition (masterbatch) has a high load of aPHA (30 to 50 wt % based on the total amount of the composition). A method for production of the composition includes two or more split feedings of the aPHA in a blending or mixing or compounding operation. The method includes feeding about 1-15 weight percent (wt %) of the total aPHA in a primary feed hopper of a blending or mixing or compounding apparatus and about 30-49 weight percent downstream in the process.

Biodegradable polyester article comprising enzymes. The present invention relates to novel biodegradable plastic articles comprising a polyester and biological entities able to degrade such polyester, and wherein the biological entities are homogeneously dispersed in the plastic articles. The invention also relates to a process for producing such plastic articles, comprising a step of mixing biological entities with a selected carrier in a liquid composition or in a masterbatch with the polyester.

The present disclosure relates to thermoplastic resin modifier compositions, methods for converting the compositions into functional resins, and to plastic articles prepared from the resins.
