AQUEOUS INK, INK CARTRIDGE, INK JET RECORDING METHOD, TITANIUM OXIDE PARTICLE DISPERSION, METHOD FOR PRODUCING TITANIUM OXIDE PARTICLE DISPERSION AND METHOD FOR PRODUCING AQUEOUS INK - A simplified explanation of the abstract

This abstract first appeared for US patent application 17937718 titled 'AQUEOUS INK, INK CARTRIDGE, INK JET RECORDING METHOD, TITANIUM OXIDE PARTICLE DISPERSION, METHOD FOR PRODUCING TITANIUM OXIDE PARTICLE DISPERSION AND METHOD FOR PRODUCING AQUEOUS INK

Simplified Explanation

The abstract describes an aqueous ink for ink jet recording that contains a titanium oxide particle with a specific surface composition and a compound acting as a dispersant for the particle.

  • The ink contains a titanium oxide particle with a surface covered in alumina and silica in specific proportions.
  • The ink also includes a compound that serves as a dispersant for the titanium oxide particle.
  • The dispersant compound is represented by a specific general formula (1).

Potential applications of this technology:

  • Inkjet printing: The aqueous ink can be used for inkjet printing applications, providing high-quality prints with improved dispersion of the titanium oxide particles.
  • Coatings: The ink can be used for coating applications, such as in the production of films or surfaces that require enhanced properties provided by the titanium oxide particles.

Problems solved by this technology:

  • Improved dispersion: The specific surface composition of the titanium oxide particle and the dispersant compound help to achieve better dispersion of the particles in the ink, preventing clumping or aggregation.
  • Enhanced print quality: The ink formulation allows for improved print quality, as the dispersed titanium oxide particles can contribute to better color reproduction and image sharpness.

Benefits of this technology:

  • High-quality prints: The ink's composition and dispersion properties result in high-quality prints with improved color reproduction and image sharpness.
  • Improved stability: The specific surface composition and dispersant compound contribute to the stability of the ink, preventing particle settling or clogging of inkjet printer nozzles.
  • Versatile applications: The ink can be used in various inkjet printing and coating applications, providing versatility and potential for different industries.
