Synthetic resin compositions

A synthetic resin composition having an alkaline pH comprising:

• 1. 0.1% to 60% by weight on a solids basis of a synthetic resin solid colloidally dispersed in an aqueous medium;
• 2. 0.01% to 5% by weight based on the weight of said resin solid, of a polyvalent metal complex coordination compound;
• 3. 5% to 90% molecular equivalent on a stoichiometric basis of said polyvalent metal, of a water-soluble ionically active ammonium or alkali metal salt of an acid capable of being chemically converted into an ionically-inactive polyvalent metal salt of said acid by chemical reaction and precipitation or sequestration of said polyvalent metal salt;
• and
• 4. carboxyl groups included in said synthetic resin or in a separately added water-soluble polymeric carboxylic thickener which carboxyl groups act to coagulate the composition.
