  • Patent number: 9995004
    Abstract: A sheet of material that reduces or eliminates the incidence of bleed-through and show-through, thereby enabling a user to prepare artwork, sketches, designs, etc. on both sides of the sheet of material, without the incidence of bleed-through or show-through. The sheet of material includes a first substrate, a second substrate, and an adhesive material positioned between the first and second substrates to operatively join the first and second substrates to each other. The adhesive material acts as a moisture barrier, thereby preventing ink or moisture from passing therethrough and saturating the second substrate when ink or moisture is applied to the first substrate and vice versa. The adhesive also serves as a light barrier, thereby reducing or eliminating show-through on the second substrate when ink or moisture is applied to the first substrate and vice versa. Multiple sheets of material may be bound into a sketch book or pad.

  • Publication number: 20080194739
    Abstract: A flame-retardant composition is obtained wherein at least one resin selected from a biodegradable resin and a plant-based resin or a PS resin is flame retarded by using a non-halogen-based flame retardancy-imparting component. At least one catalyst selected from a catalyst for purifying hydrocarbon, a catalyst for cracking hydrocarbon, a catalyst for synthesizing hydrocarbon and a catalyst for reforming hydrocarbon is used as a component conferring flame retardancy and this catalyst is kneaded with a biodegradable resin or a plant based resin such as polylactic acid and polybutylene succinate or the PS resin so as to give a resin composition. Further, the resin composition is injection-molded to give an exterior body of electric home appliance. Particularly the silica-magnesia catalyst as a flame-retardant component provides a resin composition with excellent flame-retardant characteristics, as a non-halogen-based material, in the case where polylactic acid or the PS resin is made flame retardant.
