Latest Patents

Konishi's latest patents revolve around methods for forming multilayer coating films. The first patent provides a method that offers excellent low-temperature impact resistance to substrates composed of metal and plastic materials. This method involves sequentially forming an uncured primer coating film, an uncured first colored coating film, an uncured second colored coating film, and an uncured clear coating film on a substrate. The films are then heated to simultaneously cure all four layers. The aqueous first and second colored paints used in this method are one-package type compositions that include specific hydroxyl group-containing resins and blocked polyisocyanate compounds.

The second patent aims to achieve excellent curability under low-temperature, short-time conditions while ensuring that the multilayer coating film exhibits outstanding chipping resistance and a superior finished appearance. This method involves the sequential application of an aqueous first colored coating composition, an aqueous second colored coating composition, and a clear coating composition to a substrate, followed by simultaneous bake-curing of the resulting multilayer coating film. The compositions used in this method include specific film-forming resins and polyisocyanate compounds, along with organometallic catalysts.
