<P>PROBLEM TO BE SOLVED: To provide a composition for a curable coating material capable of forming a coating film having not only an excellent balance of physical properties between physical strength of the coating film such as flexibility, abrasion resistance or the like of the coating film and chemical resistance of the coating film such as acid resistance, alkali resistance, alcohol resistance, resistance to oleic acid or the like but also a soft touch feel. <P>SOLUTION: The composition for a curable coating material essentially comprises the components (a), (b) and (c) as follows: the component (a) is a polyisocyanate compound having at least two isocyanate groups in a molecule; the component (b) is an aliphatic polycarbonate diol composed of a repeating unit of formula (1) and a repeating unit of the following formula (2), -[-O-(-CH<SB>2</SB>-)<SB>4</SB>-O-CO-]-; and the component (c) is a silica-based matting agent having an average particle size of 0.1-10 μm. <P>COPYRIGHT: (C)2010,JPO&INPIT |
