Cognis patents water-based
radiation curable epoxy
acrylate dispersions
WO2011032673
Water based radiation curable epoxy acrylate dispersions (comprises (a) an epoxy
acrylate resin with two acrylate groups per
molecule, and (b) a dispersant with at least
one acrylate group per molecule. The dispersion is obtained by (i) reacting a compound (A) with a compound (B) optionally
in the presence of a catalyst, (ii) reacting
the resulting reaction mixture having compound A with a compound (C) optionally
in the presence of a catalyst, (iii) reacting
the resulting reaction mixture with acrylic
acid and (iv) dispersing the resulting reaction mixture in water. The dispersion is obtained by initially (i) reacting at least one
compound (A) comprising non-ionic compounds having a hydrophilic-lipophilic
balance (HLB)-value of less than 12 and at
least two oxirane groups per molecule with
at least one compound (B) comprising non
ionic compounds having a HLB-value of
12-20 and at least hydrogen-acid group
per molecule, optionally in the presence of
a catalyst, where the compounds (A) and
(B) are in an equivalent ratio of 1.3:1-
400:1, (ii) reacting the resulting reaction
mixture having at least one non ionic compound with a HLB-value less than 12 and
at least two oxirane group per molecule
(compound A) with at least one compound
(C) comprising non ionic compounds with
a HLB-value less than 12 and at least a hydrogen-acid group per molecule, optionally in the presence of a catalyst, where the
compounds (A) and (C) are in an equivalent ratio of 1.1:1-20:1, (iii) reacting the resulting reaction mixture with acrylic acid
by ring opening of all epoxy groups, optionally in the presence of a catalyst and
(iv) dispersing the resulting reaction mixture in water. An independent claim is also
included for producing the aqueous radiation curable epoxy acrylate dispersion by
the method mentioned above). CW
