Aqueous organic-inorganic hybrid composition

摘要

Disclosed is an organic-inorganic hybrid composition containing a metal oxide (A) having a particle diameter of 1-400 nm and a polymer emulsion particle (B) having a particle diameter of 10-800 nm. The polymer emulsion particle (B) is obtained by polymerizing a hydrolyzable silicon compound (b1) and a vinyl monomer (b2) having a secondary and/or tertiary amide group in the presence of water and an emulsifying agent.

1. An aqueous organic-inorganic hybrid composition characterized by comprising:
a metal oxide (A) having a particle size of 1 to 400 nm; and a polymer emulsion particle (B) having a particle size of 10 to 800 nm, obtained by polymerizing a hydrolyzable silicon compound (b1) and a secondary amide group-containing vinyl monomer (b2) in the presence of water and an emulsifier, wherein an amount of the secondary amide group-containing vinyl monomer (b2) used for obtaining the polymer emulsion particle (B) is more than 0 and 0.5 or less in terms of a mass ratio (b2)/(B) of the secondary amide group-containing vinyl monomer (b2) to the polymer emulsion particle (B) to be obtained, and the polymer emulsion particle (B) is a core/shell structure formed of two or more layers, wherein each of the core and shell comprises a polymer, and wherein the core and the shell are different from one another.
