| Abstract: |
Water-based coating composition comprising: (a) from 0.5 to 90% by weight of at least one epoxy resin other than self-dispersing epoxy resins; (b) from 0.5 to 90% by weight of at least one (meth)acrylate of a polyol; (c) from 5.0 to 98.0% by weight of water; and (d) from 0.5 to 10% by weight of one or more dispersants; wherein the at least one (meth)acrylate comprises at least two (meth)acrylate groups per molecule, and wherein the Brookfield viscosity of the composition is less than 15000 mPas.

1. A water-based coating composition consisting of: (a) from 0.5 to 90% by weight of at least one epoxy resin other than self-dispersing epoxy resin; (b) from 0.5 to 90% by weight of at least one (meth)acrylate of a polyol; (c) from 5.0 to 98.0% by weight of water; and (d) from 0.5 to 10% by weight of one or more dispersants; wherein the at least one (meth)acrylate comprises at least two (meth)acrylate groups per molecule, and wherein the Brookfield viscosity of the composition is less than 15000 mPas.
