CI Basic Red refers to a category of basic red dyes that are colorants widely used in various industries, including textiles, paper, and inks. The term "CI" stands for Colour Index, which is a standardized system used to identify and categorize dyes and pigments based on their chemical and structural properties.
CI Basic Red dyes typically possess a vibrant red color and are synthesized from various chemical compounds. They are classified as basic dyes due to their cationic properties, meaning they have a positive charge and can easily bind to negatively charged substrates, such as fibers or paper, through ionic interactions. Basic dyes are often chosen for their excellent brightness, color intensity, and lightfastness.
The specific identification of CI Basic Red dyes is presented by a color index number, followed by the name "Basic Red," and additional numerical codes may denote specific chemical structures or modifications. This enables manufacturers, designers, and researchers to easily reference and compare different dyes within this category.
CI Basic Red dyes are commonly used in the textile industry for dyeing natural and synthetic fibers, imparting vivid and long-lasting red hues to fabrics. They are also utilized in the production of colored inks, including those used in printing and writing instruments, as well as in the paper industry for producing colored paper and board. The versatility and wide availability of CI Basic Red dyes make them valuable tools for achieving a broad range of vibrant red colors in various applications.
