Paint composition, process for producing wear-resistant coating film using the same, and wear-resistant coating film comprising the same

摘要

A paint composition includes a layer organic-inorganic composite, and titanium alkoxide in an amount of from 1 to 50 parts by weight with respect to the layer organic-inorganic composite taken as 100 parts by weight. The layer organic-inorganic composite is composed of a laminated substance. The laminated substance includes a tetrahedral structural layer and an octahedral structural layer. The tetrahedral structural layer is made of tetrahedral structures whose central atom M' is Si or a first metallic atom substituting for a part the Si, at least a part of the central atom M' covalent-bonded to an organic group R involving or free from a polymerizable functional group. The octahedral structural layer is made of octahedral structures whose central atom M is a second metallic atom.
