This silica cake is characterized by being a cake of precipitated silica having BET specific surface area of at least 220 m 2 /g, and when it is dispersed in ion-exchange water to provide an aqueous dispersion of the silica of 5% by weight in concentration and further diluted to reduce the silica concentration to 1.5% by weight, the dispersion having a light-scattering index (n-value) of at least 2. This silica cake can be obtained by simultaneously adding an alkali silicate and a mineral acid to a reaction liquid whose pH is being maintained at a fixed value within a range of 7.5 - 11.5 and whose temperature is being maintained at not lower than 90°C, whereby forming precipitated silica through their reaction, and separating said precipitated silica from the reaction liquid in wet state.

摘要： A method of producing a laminate comprising preparing a substrate having curved surfaces; applying a photpolymerizable and curable composition containing a photochromic compound and a phosphorus-containing photopolymerization initiator onto the curved surfaces of the base member; and curing the photopolymerizable and curable composition by the irradiation with an active energy ray having a relative intensity profile of 0 to 5% of wavelength components of not shorter than 200 nm but shorter than 300 nm, 25 to 75% of wavelength components of not shorter than 300 nm but shorter than 400 nm and 25 to 75% of wavelength components of not shorter than 400 nm but not longer than 500 nm while maintaining the substrate at not higher than 100°C. This method makes it possible to form a homogeneous and thin film containing a photochromic compound at a high concentration and having a uniform thickness on the substrate having a curved surface, such as a spectacle lens that is generally available, and to impart photochromic properties while maintaining excellent mechanical and optical properties of the substrate.
