  • Color coating compositions
    Patent number: 6262187
    Abstract: Objects of the present invention are to provide colored coating compositions which can form easily a colored glass gel coating film being excellent in water resistance, boiling water resistance, alkali resistance, weather resistance, etc. at low temperatures on the outer surface of glass products, metal products, etc. and to provide colored coating compositions with which colored bottles having no haze can be obtained even if the bottles are coated in a high-humidity environment. The colored coating compositions according to the present invention comprise a sol-gel liquid obtained by polycondensation of phenyltrialkoxysilane or an oligomer thereof, acryl polyol, polyester polyol, polyether polyol and/or lower alkyl polyol (or the acryl polyol, the polyester polyol and/or the polyether polyol and a polyisocyanate resin), and an organic coloring agent.
