a procedure for an efficient recovering of reflectance spectra of acrylic paint samples from cie tristimulus color values is described. by fixing a certain criteria based on color difference value, the proposed technique preliminarily selects a series of suitable samples from a main dataset containing the reflectance values of a series of different acrylic paint samples, based on the color spec...

The water-based paints now frequently used for house painting still contain small amounts of volatile organic compounds (VOCs), with the potential to exacerbate symptoms of asthma. Because of these potential problems and environmental concerns, some manufacturers have produced paints with no VOC content. We wished to compare the effects on asthmatics of conventional water-based paint and the ne...

The photocatalytic effect of TiO2 has great potential for the disinfection of surfaces. Most studies reported in the literature use UV activation of TiO₂, while visible light has been used only in a few applications. In these studies, high concentrations of TiO₂, which can compromise surface properties, have been used. In this work, we have developed an acrylic-water paint dispersion containing...

This white paper discusses methods and findings from one of Novetta’s many approaches to vulnerability assessment: the fabrication of non-gelatinous artifacts for capacitive fingerprint sensors. We present methods of evaluating artifact performance relative to that of live presentations and gummy fingerprint artifacts. Two sets of artifacts are comprised of latex face paint or acrylic fabric pa...

A procedure for an efficient recovering of reflectance spectra of Acrylic paint samples from CIE tristimulus color values is described.

The purpose of this study was to assess color alteration of the paints used for iris painting in artificial eyes. Five disks of heat cured acrylic resin were confectioned by microwave energy for each paint analyzed, in a total of 40 specimens. Each specimen consisted of a colorless acrylic resin disk and another of equal size, of scleral white colored acrylic resin, with the painting interposed...

In recent years, with the rapid development of building industry in western cities during period “Western Development” China, paints has developed rapidly and become more mature. addition, waterborne inorganic exterior wall have been a great choice because their reduced volatile organic compounds (VOCs) less toxicity odor. However, problem stain resistance for not solved, which major obstacle t...

The migration tests of cadmium (Cd) and lead (Pb) from paint film on baby toys set out in the Japanese Food Sanitation Law (official standard) and International Standard 8124-3 (ISO) were compared. Vinyl chloride resin enamel and acrylic resin enamel containing 1,000 mg/kg Cd and Pb on a dried basis were painted on glass plates and then dried. According to the official standard, the paint films...
