Abstract
Provided is a cured product using a composition that is capable of quick curing at low temperatures while having sufficient pot life at room temperature, a method of producing the same, a laminate, and an optical device. A method of producing an organopolysiloxane cured product is provided. The method includes: (i) performing, without irradiating with high-energy radiation, a hydrosilylation reaction upon a composition containing a first hydrosilylation reaction catalyst that exhibits activity in the composition and a second hydrosilylation reaction catalyst that does not exhibit activity when not irradiated with high-energy radiation, but exhibits activity in the composition when irradiated with high-energy radiation, to obtain a thickened material that is fluid at room temperature or a thermoplastic material that is non-fluid at room temperature but exhibits fluidity at 100° C.; and (ii) irradiating the thickened material or thermoplastic material obtained in step (i) with high-energy radiation to obtain a cured product.
