HIGH SOLIDS COATING COMPOSITION, AND COATED ARTICLES AND COATING PROCESS USING THE SAME

摘要

A high solids coating composition comprising: 100 parts by weight of a mixture of resinous solid matter comprising a polyol resin and a curing agent capable to react with hydroxyl groups: and 1~100 parts by weight of a crosslinked polymer fine particles having a hydroxyl value, (OHV)g, being in a relation with a hydroxyl value, (OHV)r, of said polyol resin, as defined by the inequality: 0 ? I(OHV)r - (OHV)g I ? 160. The crosslinked polymer fine particles have only hydroxyl groups as a reactive functional group on the particle surface and when these particles consist of at least two different kinds, a difference, x, between maximum and minimum hydroxyl values in all the crosslinked polymer fine particles is preferred to satisfy the inequality: 0 < x ? 120. The high solids coating composition of the invention exhibits highly balanced flow controlling and excellent sag prevention and flake-like pigment orientation effects, yielding leveled, brilliant coating films having excellent appearance and high film performance.
