A laminate body (1) is provided with a transparent substrate (10) and a refractive layer (11) which refracts incident light towards the top of the substrate (10). The refractive layer (11) contains, at least, one kind of fluorine compound (ss) selected from a group consisting of fluoro-silsesquioxane and fluoro-silsesquioxane polymers, and a resin (pl) having a refractive index higher than that of the aforementioned fluorine compound (ss). Of the side of the substrate (10) (the side of the back surface s2) and the side opposite thereof (the side of the front surface s1), the concentration of the fluorine compound (ss) in the refractive layer (11) is higher on said side opposite (the side of the front surface s1), and the refractive layer (11) forms a graded structure layer of high refractive indices and low refractive indices inside the layer.

Provided is a silicone resin-coated silicone elastomer particle that is superior in dispersibility into organic resins, in stress relaxation performance, and the like, and that has low dust scattering when mixing and thus is superior in ease of handling. Also provided is an organic resin additive, an organic resin, a coating composition, or a coating agent composition, and applications such as in cosmetic compositions, including the particle. The silicone resin-coated silicone elastomer particle has a structure wherein at least two silicon atoms in a silicone elastomer particle are cross-linked through a silalkylene group with a carbon number between 4 and 20 where some or all of the surface thereof is coated with a silicone resin structured from siloxane units expressed by SiO.sub.4/2.

This disclosure enables direct 3D printing of preceramic polymers, which can be converted to fully dense ceramics. Some variations provide a preceramic resin formulation comprising a molecule with two or more CX double bonds or CX triple bonds, wherein X is selected from C, S, N, or O, and wherein the molecule further comprises at least one non-carbon atom selected from Si, B, Al, Ti, Zn, P, Ge, S, N, or O; a photoinitiator; a free-radical inhibitor; and a 3D-printing resolution agent. The disclosed preceramic resin formulations can be 3D-printed using stereolithography into objects with complex shape. The polymeric objects may be directly converted to fully dense ceramics with properties that approach the theoretical maximum strength of the base materials. Low-cost structures are obtained that are lightweight, strong, and stiff, but stable in the presence of a high-temperature oxidizing environment.

A radiation curable article includes a silicone composition including a silicone oligomer and a photoactive catalyst, wherein the silicone oligomer comprises at least one alkenyl group and at least one hydride group, the radiation curable silicone oligomer having a viscosity of less than about 100,000 centipoise prior to cure. Further included is a method of forming a radiation curable article includes providing a silicone composition including a silicone oligomer and a photoactive catalyst, wherein the silicone oligomer includes at least one alkenyl group and at least one hydride group, the silicone oligomer having a viscosity of less than about 100,000 centipoise prior to cure; and irradiating the silicone composition with a radiation source.
