Claims (4)

1. A paint consisting of water, a colorant, and resin particles comprising a polymerization product of reactants comprising a dioxane/dioxolane monomer and a vinyl co-monomer, wherein the dioxane/dioxolane monomer is an ester of (meth)acrylic acid with an alcohol comprising a dioxane moiety, an ester of (meth)acrylic acid with an alcohol comprising a dioxolane moiety, or both, wherein the resin particles have a D 50 particle size in a range of from about 100 nm to about 400 nm, wherein the resin particles consist of the polymerization product of the reactants and the reactants consist of glycerol formal (meth)acrylate, styrene, butyl (meth)acrylate, beta-carboxyethyl acrylate, an initiator, and optionally, a crosslinking agent.

2. The paint of claim 1 , wherein the dioxane/dioxolane monomer is present in the resin particles at an amount in a range of from about 1 weight % to about 50 weight %.

3. The paint of claim 1 , wherein the butyl (meth)acrylate is present in the resin particles at an amount of at least about 15 weight %.
