摘要:
Fluorescent functional dyes represented by the following formulas: 1 wherein R1 is hydrogen or methyl; R2, R3, R4, R5, and R6 are each independently selected from the group consisting of hydrogen, alkyl, aryl, alkoxy, aralkyl, alkaryl, halo, and trifluoromethyl; and L is a straight chain or branched chain alkylene containing 3 to about 15 carbon atoms, the alkylene group optionally containing one or more catenary heteroatoms.
摘要:
Thermoplastic composition comprising a thermoplastic resin and a phosphorescent pigment with a aluminate matrix expressed by MnullAl in which M is at least one metal element selected from calcium, strontium and barium and Al represents an aluminate group, wherein the pigment has been coated with a silicone oil. Objects formed by injection molding of the thermoplastic resin compositions. The compositions of the invention exhibit improved melt flow stability and suffer less from graying upon compounding them in an extruder.
摘要:
A photoluminescent thermoplastic multi-component fiber comprising a pigmented component and processing enhanced luminescence and mechanical properties. Most suitably, the pigmented component comprises between 5% and 30% by weight of photoluminescent pigment and the pigmented component is between 20% and 50% by weight of the multi-component fiber. The multi-component fiber can be formed from either POY or FDY, and the multi-component fiber can have many different cross section shapes including sheath/core. These single component or multi-component fibers can be made into a variety of fabrics. Additionally, single component or multi-component fibers can also be formed into single or multi-component meltblown and spunbonded fabrics.
摘要:

摘要:
A liquefied color phosphorescent material consisting of a mixture which comprises a stock solution; a colorant; a color-emitting phosphorescent fine pigment particle having an average particle diameter of 7 nullm or less; and an additive for stably dispersing pigments containing a cellulose-based synthetic resin, silica-based powder, cyclohexanone, isophorone and mineral spirit. The pigment particles of colorant and the color-emitting phosphorescent fine pigment particle are enabled to be always maintained in a substantially uniform dispersion state in the stock solution, thereby making it possible to attain a desired emitting color and to coat the phosphorescent material without necessitating the under-coating using a color paint.
摘要:
A composition for a fluorescent marking paste or paint that is non-toxic, water soluble, clear drying and safe for nonporous surfaces is disclosed. The invention is composed of a generic white school paste or any other water soluble, non-toxic, clear drying paste or cement to which non-toxic fluorescent or phosphorescent colorant particles and water are added. The consistency of the resultant mixture is either a paste for making an impression or a paint for applying to a non-porous object using a brush, and the paste or paint, when dry, is clearly visible under UV light. Unique identifying marks such as identifying stamps, actual fingerprints, or numbers may be placed on any nonporous object that can be safely cleaned with a damp cloth. This invention provides a safe marking system for allowing e-commerce sellers to prevent buyer fraud or for allowing owners to identify possessions for inventory and insurance purposes. The identifying mark may be deliberately removed by the owner without causing any harm or damage to the object.
摘要:
High solubility of pristine single and multi-walled carbon nanotubes using electron donors as solubilizers has been observed. The resulting carbon nanotube solution can be readily diluted with other organic solvents, such as acetone, toluene and methanol. SEM after solvent evaporation clearly shows that nanotubes are still present after being subjected to this procedure. Electronic absorption of these solutions is observed in both the UV and visible region. Strong light emission (null0.30) was observed at 561 nm for dilute solutions of aniline-dissolved carbon nanotubes diluted with acetone.
摘要:
A composition containing a high-molecular compound having as a photo-crosslinkable group any of a cinnamoyl group, a cinnamylidene group, a chalcone residual group, an isocoumarin residual group, a 2,5-dimethoxystilbene residual group, a thymine residual group, a styrylpyridinium residual group, an null-phenylmaleimide residual group, an anthracene residual group and a 2-pyrone residual group, or an aromatic bisazide, is cross-linked by light irradiation via a mask to cure the composition in a prescribed pattern to form photoemission layers.
摘要:
A new phosphorescent ink composition including a micro-capsulated phosphorescent pigment for ink jet printing is disclosed. The phosphorescent ink composition not only promotes the printing quality, enhances light fastness of colorants, and promotes luster of color but also shows the unique luminescent colors in dark. The ink composition includes at least one phosphorescent pigment, at least one colorant providing an ink color, and a vehicle comprising an organic solvent having a predetermined concentration, and at least one surfactant. The phosphorescent pigment is micro-capsulated in a resin film and is dispersed in the vehicle. The phosphorescent pigment is ground to a diameter of less than 1 micron in advance.
