<p><P>PROBLEM TO BE SOLVED: To provide water-based one package coating excelling in curability, coating film performance such as hardness, acid resistance and scratch resistance, coated surface smoothness and aqueous dispersion stability. <P>SOLUTION: The water-based one package coating comprises acrylic resin having specific long chain primary hydroxy-containing side chains as crosslinking functional groups and having a solubility parameter of 9.30-11.20, and a blocked polyisocyanate compound having a solubility parameter of 9.00-11.50, the differenceΔSP between the solubility parameter (SP1) of the acrylic resin and the solubility parameter (SP2) of the blocked polyisocyanate compound (ΔSP=(SP1)-(SP2)) being -0.80-1.50. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
