Ooya’s listed inventions address the performance of automotive and other coating films, with a focus on smoothness, distinctness of image, water resistance, and chipping resistance.

“Method for Forming Multilayer Coating Film” describes applying two water-based coloring paints in succession and then heating and curing the resulting layers simultaneously. The first paint includes hydroxy-containing polyester resin, a curing agent, and water-dispersible acrylic resin. The patent describes a monomer composition for that acrylic resin that includes C5–22 alkyl-containing polymerizable unsaturated monomers.

“Water-Based Paint Compositions” concerns paint formulations containing an aqueous film-forming resin, a curing agent, and crosslinked resin particles with a core/shell multilayer structure. The core is formed from specified polymerizable unsaturated monomers, while the shell has a crosslinked structure. The invention aims to produce coating films with improved smoothness, image clarity, water resistance, and chipping resistance.
