Title:
METAL OXIDE DISPERSION, METAL OXIDE DISPERSION-CONTAINING POLYMERIZABLE COMPOSITION, AND POLYMERIZED PRODUCT OF SAME
Document Type and Number:
WIPO Patent Application WO/2013/161859
Kind Code:
A1
Abstract:
The present invention addresses: the problem of providing an organic-inorganic hybrid acrylic polymer which has increased refractive index and higher transparency, while being suppressed in decrease of abrasion resistance; the problem of providing a metal oxide dispersion and a polymerizable composition, each of which serves as a starting material for the polymer; and the problem of providing the organic-inorganic hybrid polymer which can be prevented from the occurrence of cracks during the production procedure. The present invention also addresses the problem of providing an antireflection film which utilizes the organic-inorganic hybrid polymer and exhibits high performance. A metal oxide dispersion of the present invention contains a phosphorus compound represented by formula (1) and a metal oxide. (In formula (1), R1 represents a hydrogen atom, an alkyl group, an alkynyl group, an alkenyl group, an aryl group, an aliphatic heterocyclic group or an aromatic heterocyclic group; R2 represents an organic residue; and n is 1 or 2.)
