Measurement of fluorescent white effects and whiteness. 荧光白效果和白度的测量。
Environmental quality and safety. Supplement
Pub Date : 1975-01-01
G Anders

This report surveys the literature and describes various techniques of whiteness measurement and evaluation in current use. Measuring techniques are described for dealing separately with the effects obtained by bleaching, blueing and fluorescent whitening, and an example is given of the direct quantitative estimation of a fluorescent whitening agents (FWAs) on a substrate by measuring reflectance in the ultraviolet region. Another chapter deals with the colorimetric estimation of the whiteness and the shade of a fluorescent white using modern apparatus in conjunction with a programmable minicomputer. A new simple and universally applicab,e formula was worked out: W=D-Y+P-x+Q-y+C which has been successfully used in routine tests and which for the first time gives different weight to whiteness values corresponding to all shade preferences existing in theory. Each user can match the formula to his own preference by appropriate adjustment of the D, P, Q andC values. Y,x and y are the customary colorimetric values as standardized by the CIE (Commission Internationale de l'Eclairage). It was also found that with another formula the shades of fluorescent whitening effects (green to red tints) may be defined in a simple way.

本报告综述了文献，并描述了目前使用的各种白度测量和评价技术。介绍了分别处理漂白、蓝化和荧光增白剂效果的测量技术，并给出了通过测量紫外区反射率直接定量估计荧光增白剂作用于衬底的例子。另一章讨论了利用现代仪器结合可编程小型计算机对荧光白色的白度和阴影的比色估计。本文提出了一个简单而又普遍适用的公式:W=D-Y+P-x+Q-y+C，该公式首次在常规试验中得到了成功的应用，并对理论上存在的各种色度偏好对应的白度值给出了不同的权重。每个用户可以通过适当调整D, P, Q和c值来匹配自己的偏好。Y、x和Y是由国际照明委员会(CIE)标准化的习惯比色值。还发现，用另一种配方，荧光增白效果的色调(绿色到红色)可以用一种简单的方法来定义。

Testing mutagenic properties with the dominant lethal test on the male mouse. 用显性致死法对雄性小鼠进行诱变特性试验。
Environmental quality and safety. Supplement

D Lorke, L Machemer

Mytagecity studies were carried out with fluorescent whitening agents (FWAs) using the dominant lethal test on male mice. Own tests with five FWAs, and those of KEPLINGER, et al. (Toxicol. Appl. Pharmacol.27: 494-506, 1974), with four FWAs, are described. In our tests, acute oral administration of five FWAs at a dose of 5000 mg/kg body weight gave no evidence of a mutagenic effect during 8 weeks' mating. The FWAs used were three bis(triazinylamino)stilbenedisulfonic acid derivatives and a 1,3-diphenyl-2-pyrazoline derivative. The results of the tests carried out by KEPLINGER, et al. showed that intraperitoneal injection of the four FWAs produced no mutagenic effect during six weeks' mating; the whiteners used were a triazolylstilbenemonosulfonic acid derivative (50 mg/kg), two bis(triazinylamino)stilbenedisulfonic acid derivatives (50 mg/kg) and a bis(sulfostyryl)biphenyl derivative (10 mg/kg).

用荧光增白剂(FWAs)对雄性小鼠进行了显性致死试验。自己用5个FWAs和KEPLINGER等的测试(毒理学杂志)。达成。药物。27:494-506,1974)，与四个FWAs描述。在我们的试验中，在8周的交配期间，以5000 mg/kg体重的剂量急性口服5种FWAs，没有证据表明有诱变作用。所使用的FWAs是三个双(三嗪胺)二苯二磺酸衍生物和一个1,3-二苯基-2-吡唑啉衍生物。KEPLINGER等人的实验结果显示，在交配6周期间，腹腔注射这4种FWAs没有产生诱变作用;所使用的增白剂为一种三唑基二苯乙烯单磺酸衍生物(50 mg/kg)、两种二(三嗪胺)二苯乙烯二磺酸衍生物(50 mg/kg)和一种二(磺基苯乙烯)联苯衍生物(10 mg/kg)。

Psychological aspects of white. 心理方面的白。
Environmental quality and safety. Supplement
Pub Date : 1975-01-01
M Lüscher

An attempt is made to answer the questions: Is white a color? How do we see fluorescent and non-fluorescent whites? What is the psychological and symbolic significance of white? A qualitative study was based on a sample of 1818 people from 24 differentiated groups from the age of 6 upwards. Two techniques were used in the enquiry: the well-known word association test, and a non-verbal method, new to psychology, which was devised specifically for the purpose of defining the psychological significance of white by emotional reference to a set of grey shades, a set of chromatic colors and a set of simple shapes. In a quantitative study, a sample of 1994 people were asked their reactions to fluorescent and non-fluorescent whites. This work was supplemented by linguistic investigations of the anthropological and physiological significance of white. The conclusion reached is that white meets a psychic need in man. Almost all the respondents attributed the characteristic of "whiteness" only to fluorescent whites.

试图回答以下问题:白色是一种颜色吗?我们如何看待荧光白色和非荧光白色?白色的心理和象征意义是什么?一项定性研究的样本是1818人，他们来自24个不同的群体，年龄从6岁以上。在调查中使用了两种技术:一种是众所周知的单词联想测试，另一种是非语言的方法，这是心理学上的新方法，它是专门为定义白色的心理意义而设计的，通过对一组灰色阴影、一组彩色和一组简单形状的情感参考。在一项定量研究中，1994人被问及他们对荧光白色和非荧光白色的反应。这项工作还补充了对白色的人类学和生理学意义的语言学调查。得出的结论是，白色满足了人类的精神需求。几乎所有的受访者都将“白”的特征归因于荧光白色。
