The reactions were monitored by TLC and the melting point of the products was determined by open capillary method. Stabilising the action of PCPF, PNPF for protecting paint against thermal oxidation was tested using a QUV weatherometer. The effect of exposure on the properties of paints such as gloss, whiteness and yellowness were evaluated. Results show that paints containing these new polymeric antioxidants possess better stabilising effects against photo-oxidation than those employed in standard paints available in the market.

Vitamine CIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this study, chrome tanned bovine crust leathers were dyed white during finishing process. Experiments with 1%, 2%, 3%, 4% and 5% L-ascorbic acid addition were performed on the finishing layer of the finishing application. L-ascorbic acid was not added to the control group and processed according to the standard method. After these processes, color measurement analyzes were performed on Konica Minolta CM 3600d spectrophotometer. In order to investigate the effects of L-ascorbic acid on other performance properties of leather, light fastness test according to TS 1008 EN ISO 105-B02 (2001 TS EN ISO 11640 2001) and dry rub fastness test according to standard method were performed. The results of the study were statistically evaluated according to the NCSS (Number Cruncher Statistical System) method. As a result of the research, it was observed that L-ascorbic acid gave a pearly pink color to the leathers. It was found that the dry rubbing fastness of the leathers treated with L-ascorbic acid improved. In the light fastness tests, the results of the experimental group leathers were recorded better by the blue scale.

Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : UV-curable water-borne coatings are attracting more attention due to th ecombined advantages of UV-curing systems and water-borne coatings, which include matting ease, handling efficiency, the fact they are monomer free, and offer a faster manufacturing throughput. However, good chemical resistance and physical drying can be a challenge. Two new approaches have turned this around, and offer good chemical resistance, hardness, and physical drying for clear and pigmented coatings.

Translucidité (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : Translucency is a critical property of print on flexible packaging. It forms the basis for obtaining full color gamut, hiding the contents of a package and even creating the scanner readable digital codes for point of purchase tracking. The print industry has followed the paint and decorative coatings industry, the paper industry and the plastics industry in attempting to identify measurement methods that will accurately describe translucency or its opposite, opacity. Both of these properties are defined in terms of the contrast ratio, the ratio of the luminous reflectance of a coating placed over a black and a white substrate. In this paper, the theory of diffuse reflectance spectroscopy is used to define the measurements used to determine the contrast ratio. A brief experimental study illustrates the strong points and weak points of traditional contrast ratio measurements. A better model of contrast ratio determination is hypothesized, and an experiment is designed and reported that demonstrates both the validity of the hypothesis and a method for obtaining consistent estimates of the contrast ratio.
