  • Patent number: 10190006
    Abstract: Method for decorating green or fired ceramic bodies by inkjet printing including the use of a ceramic inkjet ink which is prepared by milling a ceramic inorganic pigment in an organic medium in the presence of a dispersing agent which is the reaction product of a polyethyleneimine and a 12-hydroxystearic acid and ?-caprolactone co-polyester, until the average particle size of the pigment is between 0.1 and 0.8 ?m.
    Type: Grant

  • Patent number: 9580616
    Abstract: Compound of Formula (1); wherein: Zw is an organic radical comprising w amino groups, in which w is a number and 5?w?3,000; A and B are independently oxy-C1-C20-alkylene carbonyl groups or oxy-C2-C20-alkenylene carbonyl groups derived from hydroxy carboxylic acids or lactones; T is hydrogen or R—CO—, where R is a C1-C50 hydrocarbyl group; Y is a C3-C4-alkylene radical linked to an amino group of Zw; Y? is an ionic salt link between an amino group of Zw and the terminal carbonyl of (A)r-(B)p-T; r and p are independently numbers between 0 and 50 and r+p>2; s, m and v are numbers; 0.99w?s+m?2w; and 0.3w?s+v?2w are suitable as dispersants and milling aids.
