FLUORESCENT POLYACRYLATE DISPERSIONS |
摘要 |
An aqueous secondary polyacrylate dispersion comprising a fluorescent dye. The dispersion is obtainable by a method comprising the steps of: a) reacting a first reaction mixture comprising: (M1) hydroxy-functional, free-radically polymerizable monomers; and (M2) hydroxyl-and carboxyl-free (meth)acrylic esters having C1 to C8hydrocarbon radicals in the alcohol moiety and/or vinyl aromatics, thereby obtaining a first reaction mixture product; b) adding a second reactionmixture comprising: (M3) acid-functional, free-radically polymerizable monomers; and (M4) hydroxyl-and carboxyl-free (meth)acrylic esters having C1 to C8hydrocarbon radicals in the alcohol moiety and/or vinyl aromatics to the first reaction mixture product, followed by the reaction of the mixture thus obtained and thereby obtaining a second reaction mixture product; wherein the first reaction mixture further comprises: (M5) nitrile-functional, free-radically polymerizable monomers and the method further comprises the steps adding a neutralizing agent and water and adding a fluorescent dye. The invention furthermore relates to its use as a fluorescent ink and to a method of producing such a dispersion. |
