Claims
- 1. A substrate coated with a dried and cured layer of a coating composition of an organic liquid carrier, a film forming binder and about 1-50% by weight of the pigment dispersion, wherein the pigment dispersion comprises dispersed pigment, a carrier liquid and an AB-block polymer dispersant (binder);the AB block polymer has a number average molecular weight of about 5,000-20,000 and consists of 20-80% by weight of a polymeric A segment and correspondingly 80-20% by weight of a polymeric B segment; wherein the polymeric A segment of the block polymer consists essentially of polymerized glycidyl (meth)acrylate monomers reacted with an acid selected from the group consisting of aromatic carboxylic acids and aliphatic carboxylic acids; and the polymeric B segment containing reactive hydroxyl groups consists essentially of polymerized alkyl (meth)acrylate monomers having 1-12 carbon atoms in the alkyl group and hydroxy alkyl (meth)acrylate monomers having about 1-4 carbon atoms in the alkyl group and wherein the weight ratio of pigment to binder in the dispersion is about 1/100-200/100.
- 2. The substrate of claim 1 having superimposed thereon a clear layer of a coating composition.
