Title:
POLYESTER-POLYACRYLATE DISPERSION WITH REACTIVE DILUENT BASED ON HYDROXY-FUNCTIONAL ESTER
Document Type and Number:
Japanese Patent JP2006193720
Kind Code:
A
Abstract:

To provide a polymer dispersion able to be produced without using an emulsifier or a large amount of solvent and giving a coated product having good mechanical and optical characteristics.

The method for producing the water-based hydroxy functional polyester-polyacrylate dispersion is to prepare a polymer P in a first process by polymerizing a mixture of free radically copolymerizable vinyl monomers in the presence of a reaction product of glycidyl versatate, mixing the polymer P with ≥1 polyester polyols having 10-500 mgKOH/g solid hydroxyl value and >0.5 to ≤30mgKOH/g solid acid value, and dispersing the prepared polymer mixture in water before or after adding a neutralization agent. The prepared water-based hydroxy functional polyester-polyacrylate polymer dispersion and a water-based coating composition containing the dispersion are provided.
