Abstract:
An oxygen-scavenging mixture comprising the components (I) a nano-sized oxidizable metal component wherein the average particle size of the metal is 1 to 1000 nm and wherein the metal is unsupported or supported by a carrier material, (II) an electrolyte component, and (III) a non-electrolytic, acidifying component.
Abstract:
Disclosed is an ultraviolet absorber water-dispersed composition, comprising the following components (A) and (B); (A) a benzotriazole-type ultraviolet absorber represented by general formula (1 ) below wherein R1 and R2 denote alkyl groups having a carbon number from 1 to 18, may be identical or different, and may be substituted by one or two or more groups selected from the group consisting of alkyl groups having a carbon number from 1 to 4, and cycloalkyl groups and aryl groups both having a carbon number from 5 to 12; and (B) polyglycerol monoalkyl ester with a mean degree of polymerization of glycerol of 5 or more. The water-dispersed composition is capable of stably maintaining the dispersed state of benzotriazole-type ultraviolet absorbers even in the presence of salt.
Abstract:
A convenient way for preparing thin layers of organic semiconducting materials comprises application or deposition of particles of a semiconducting material containing an organic semiconductor on a suitable surface, and converting these particles into a semiconducting layer on a substrate by application of pressure and optionally elevated temperatures.
Abstract:
Solid, low-dust pigment compositions are formed by mixing pigments with certain polymer stabilizers under conditions wherein the stabilizers are in a liquefied state. The pigment compositions are easily handled and have a high color yield when incorporated into polymer substrates. In many cases, the color development attained is not readily achievable using pigment compositions comprising conventional carriers.
Abstract:
The present invention relates to new compounds, which are molecular combinations of a phthalocyanine and a mono-azo dyestuff linked via specific linking groups and to a process for their preparation. Further aspects are shading compositions using these compounds.
Abstract:
The invention relates to the use of tungsten oxide or of tungstate to increase the heat-input amount of near infrared radiation in processes selected from laser welding of plastics, NIR curing of coatings, drying of printing inks, fixing of ink toners to a substrate, heating of plastic preforms, laser marking of plastics or paper.
Abstract:
The present invention relates to flame retardant polymer compositions which comprise combinations of hydroxyalkyl phosphine oxides with 1,3,5-triazine compounds and polyfunctional epoxide compounds. The compositions are in the form of epoxy laminates which are useful for the manufacture of prepregs, laminates for the preparation of printed circuit boards and printed wiring boards.
