701 results about "Lightfastness" patented technology

Lightfastness is a property of a colourant such as dye or pigment that describes how resistant to fading it is when exposed to light. Dyes and pigments are used for example for dyeing of fabrics, plastics or other materials and manufacturing paints or printing inks.

Thermally transferable image protective sheet, method for protective layer formation, and record produced by said method

Disclosed are a thermally transferable image protective sheet and a method for protective layer formation that can provide a protective layer which can protect an image of a record produced by a nonsilver photographic color hard copy recording method, can impart lightfastness and other properties to the record, and can realize a record having a glossy impression comparable to silver salt photographs. The thermally transferable image protective sheet comprises a support and a thermally transferable resin layer having a single-layer or multilayer structure stacked on the support so as to be separable from the support. The thermally transferable image protective sheet has been constructed so that, when the thermally transferable image protective sheet is put on top of a print so as for the thermally transferable resin layer to be brought into contact with an image portion in the print and the thermally transferable resin layer is thermally transferred to cover at least the image portion of the print followed by the separation of the support from the thermally transferable image protective sheet to form a thermally transferred resin layer on the surface of the print, the surface of the thermally transferred resin layer on the print has a specular glossiness of not less than 60% as measured at an angle of incidence of 20 degrees according to JIS (Japanese Industrial Standards) Z 8741.

Thermoplastic fibers exhibiting durable high color strength characteristics

Improvements in permitting brighter colorations within polypropylene fibers and / or yarns while simultaneously providing more efficient production methods of manufacturing of such colored fibers as well are provided. Generally, such fibers and / or yarns have been colored with pigments, which exhibit dulled results, or dyes, which exhibit high degrees of extraction and low levels of lightfastness. Such dull appearances, high extraction levels, and less than stellar lightfastness properties negatively impact the provision of such desirable colored polypropylene fibers and / or yarns which, in turn, prevents the widespread utilization of such fibers and yarns in various end-use applications. Thus, it has surprisingly been determined that brighter colorations, excellent extraction, and more-than-acceptable lightfastness characteristics can be provided, preferably, through manufacture with certain polymeric colorants that include poly(oxyalkylene) groups thereon. Fabric articles comprising such novel fibers and / or yarns are also encompassed within this invention.

White color reflecting material and process for production thereof

A general-use white color reflecting material, and a process for production thereof are provided. The white color reflecting material, without troublesome surface treatment such as formation of a reflective layer by plating, is capable of reflecting a near-ultraviolet ray of a wavelength region of 380 nm or longer or a near-infrared ray sufficiently without light leakage; does not become yellow even when exposed to near-ultraviolet rays; has excellent lightfastness, heat resistance, and weatherability; has high mechanical strength and chemical stability; is capable of maintaining a high degree of whiteness; and is easily moldable at a low cost. Further a white color reflecting material used as an ink composition for producing the white color reflecting material in a film shape is also provided. The white color reflecting material comprises; a silicone resin or silicone rubber formed from titanium oxide-containing silicone composition, in which anatase-type or rutile-type titanium oxide particles are dispersed.

Thermoplastic resin composition and molded product employing it

A thermoplastic resin composition and a molded product, having excellent transparency, ultraviolet absorptivity and light resistance, are provided. A thermoplastic resin composition comprising from 0.001 to 10 wt %, based on the total resin composition, of a glass filler whose glass formulation consists mainly of a silicon oxide composition and exhibiting light transmittances at wavelengths of 340 nm and 400 nm of from 0 to 0.5% and from 30 to 99%, respectively, per mm of light path length. A molded product which is a molded product of a thermoplastic resin composition, characterized in that in a case where (1) an ultra-high pressure mercury lamp which does not substantially emit ultraviolet light having a wavelength of at most 250 nm, is used at such a distance that the intensity of ultraviolet light having a wavelength of 350 nm generated by the lamp would be 0.1 W / cm2 on the surface of the molded product, and (2) the molded product is irradiated for 72 hours in the air at the surface temperature thereof being 60° C., the light transmittance at a wavelength of 650 nm after the irradiation, is at least 70% per mm of light path length.
