  • RAZORS AND RAZOR CARTRIDGES WITH COLORED BLADES
    Publication number: 20240123642
    Abstract: Razors cartridges including a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap are provided. The first blade has a first color and a second blade has a second color, where the first color is different than the second color. The blade color corresponds to an attribute of the blade (e.g., low cut force) that the color is disposed on or an attribute of the razor cartridge (e.g., sensitive skin). The color of the blade corresponds to a target user of the razor cartridge (e.g., male or female). The first blade defines a blade edge near or nearest the guard and a second blade defines a blade edge near or nearest the cap.

  • Bis aromatic anhydrides
    Patent number: 4002645
    Abstract: Novel bis-anhydrides are obtained by, for example, ferric chloride-catalyzed Friedel-Crafts reactions with polynuclear aromatic compounds and the monoacid halide of trimellitic anhydride. Melt-processable polyimides exhibiting good mechanical properties are prepared from the bis-anhydrides.
