  • Publication number: 20130141907
    Abstract: There is provided a light diffusing flame-resistant composite member which has both flame resistance and flexibility and has excellent light diffusibility. The light diffusing flame-resistant composite member of the present invention includes a glass fiber sheet and a condensation-reactive silicone resin, wherein at least one surface of the glass fiber sheet is coated with the condensation-reactive silicone resin, or the glass fiber sheet is impregnated with the condensation-reactive silicone resin, and wherein the composite member has a total light transmittance of 60% or more and a haze value of 80% or more. The condensation-reactive silicone resin may be an inorganic oxide particle-containing condensation-reactive silicone resin comprising a crosslinking structure in which inorganic oxide particles dispersed in a polysiloxane resin having a condensation-reactive group is crosslinked with the polysiloxane resin by chemical bonds.

  • Publication number: 20130115424
    Abstract: The purpose of the present invention is to provide a process for polymer member production in which a rugged surface structure is easy to control, and a polymer member obtained by the process. This process for producing a polymer member (10) having a rugged surface structure is characterized bar comprising a step (A) in which a monomer-absorbing layer (5) capable of absorbing a polymerizable monomer (2), a ruggedness transfer material layer (1) having a rugged surface (1a), and polymerizable-composition layer (4) containing the polymerizable monomer (2) are superposed so that the layer (4) is disposed between the monomer-absorbing layer (5) and the rugged surface (1a) of the transfer material layer (1) and a step (B) in which the polymerizable monomer (2) is polymerized. The process is further characterized in that the polymerizable-composition layer (4) contains an incompatible substance (3) which is incompatible with the polymerizable.

  • Publication number: 20130040131
    Abstract: Provided is a flame-retardant member having flexibility and a high degree of flame retardancy. A flame-retardant polymer member of the present invention is a flame-retardant polymer member having a polymer layer (B) and a flame-retardant layer (A) on at least one surface of the polymer layer (B), in which the flame-retardant layer (A) is a layer containing a layered inorganic compound (f) in a polymer (X).
