Abstract
บทสรุปการประดิษฐ์ซึ่งจะปรากฏบนหน้าประกาศโฆษณาReadFile:สารละลายลิวโคอินดิโกชนิดเอเควียสซึ่งประกอบรวมด้วยอะโรมาติกเอมีนในรูปแบบของอะนิลีนหรืออะนิลีนและN-เมทธิลอะนิลีน,ที่ซึ่งลิวโคอินดิโกดังกล่าวอยู่ในรูปแบบของเกลือโลหะอัลคาไล;ที่ซึ่งความเข้มข้นของอะโรมาติกเอมีนจะต่ำกว่า40ppmที่ถูกกำหนดตามISO14362-1:2017(E);และที่ซึ่งความเข้มข้นของเกลือลิวโคอินดิโกอยู่ในช่วงความเข้มข้นเป็นจาก10ถึง45%โดยน้ำหนักเมื่อเทียบกับนํ้าหนักทั้งหมดของสารละลาย,และที่ซึ่งสารละลายจะเสถียรที่อุณหภูมิเป็น23องศาเซลเซียส;หรือที่ซึ่งความเข้มข้นของเกลือลิวโคอินดิโกอยู่ในช่วงความเข้มข้นเป็นจาก45ถึง65%โดยนํ้าหนักเมื่อเทียบกับนํ้าหนักทั้งหมดของสารละลาย,และที่ซึ่งสารละลายจะเสถียรที่อุณหภูมิเป็น60องศาเซลเซียส A summary of the invention which appears on the advertisement page ReadFile:Aquaic leukoindigo solution consisting of aromatic amines in the form of aniline or aniline and N-methylaniline, where the aforementioned leukoindigo is in the form of alkali metal salts; where the aromatic amine concentration is lower than 40ppm, is defined accordingly. ISO14362-1:2017(E); and where the concentration of leukoindigo salts is in the concentration range from 10 to 45% by weight relative to the total weight of the solution, and where the solution is stable at temperature is 23 °C; or where the concentration of leukoindigo salts is in the concentration range from 45 to 65% by weight relative to the total weight of the solution, and where the solution is stable at a temperature of 60 degrees Celsius
