Abstract
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 hydrolysable 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.
Claims22
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 diethyl acrylamide monomer in the presence of water and an emulsifier,
- wherein the amount of the diethyl acrylamide monomer (b2) used for obtaining the polymer emulsion particle (B) is 0.07 or more and 0.5 or less in terms of a mass ratio (b2)/(B) of the diethyl acrylamide monomer to the polymer emulsion particle (B) to be obtained.
