115 Coating Composition, Process for Producing the Composition, andLaminate having a Hard Coat Layer Abstract [Abstract] To provide acoating composition capable of forming a hard coat layer havingexcellent transparency and scratch resistance on the surface of anoptical resin substrate such 5 as a plastic lens, and exhibitinglong-term storage stability. [Means for Solution) The coatingcomposition comprises (A) a fine particulate composite metal oxide,(B') a hydrolyzed product obtained by the hydrolysis of (B) ahydrolyzable organosilicon compound containing (B1) an organosilicon10 compound that has an epoxy group, such asey-glycidoxypropyltrimethoxysilane, (C) water, (D1) a low-boilinglowly viscous alcohol having not more than 3 carbon atoms, such asmethanol or ethanol, (D2) a low-boiling highly viscous alcohol suchas t-butanol, (D3) a high-boiling organic 15 solvent having a boilingpoint of 1501: to 200C, such as diacetone alcohol, and (E) a curingcatalyst such as tris(2,4-pentanedionato)aluminum(III), the massratio (Dl/C) of the component (D1) and the component (C) being in arange of 1.80 to 7.00, the mass ratio (D2/C) of the component (D2) 20and the component (C) being in a range of 0.24 to 2.50, and the massratio (D3/C) of the component (D3) and the component (C) being in arange of 1.10 to 4.40.
