Abstract
A water-in-oil coating composition comprising a water phase emulsified in a non-aqueous liquid phase, wherein the non-aqueous phase comprises one or more binders including an autoxidizable binder, characterized in that the composition has a solids content in the range of from 5 to 50 wt % and a water content in the range of from 40 to 90 wt %, and wherein the value A defined by the sum of the mass-average molecular mass of the one or more binders divided by 1,400, 1.7 times the solids content, and the water content, is at most 130, wherein the mass-average molecular mass is expressed in gram/mole and the solids content and the water content are each expressed in wt % based on the total weight of the composition.

A water-in-oil coating composition comprising a water phase emulsified in a non-aqueous liquid phase, wherein the non-aqueous phase comprises one or more binders including an autoxidizable binder, characterized in that:
- i. the composition has a solids content (SC) in the range of from 5 to 50 wt % based on the total weight of the composition;
- ii. the composition has a water content (WC) in the range of from 40 to 90 wt % based on the total weight of the composition;
- iii. the one or more binders have a mass-average molecular mass (Mw) expressed in gram/mole, as determined in accordance with GPC ISO 16014-1;
- and
- iv. the solids content of the composition, the water content of the composition and the mass-average molecular mass of the one or more binders are such that value A is at most 130, wherein value A is defined as:
- A=[(Mw/1400)+(1.7×SC)+WC]
- wherein Mw is expressed in gram/mole and SC and WC are each expressed in wt %.
