Patent ID: 7214422

Claim:
A glass-break preventing film filter, comprising: a reflection preventing film; and a glass-break preventing layer comprising: an adhesive layer comprising: a composite material of a transparent organic polymer substance; and an organized lamellar clay mineral, said reflection preventing film being laminated on a first side of said glass-break preventing layer, and a second side of said glass-break preventing layer comprising an adhesive face, wherein portions of the transparent organic polymer substance are intercalated between layers of the organized lamellar clay mineral, wherein an amount of said organized lamellar clay mineral includes a range of from 10 to 150 parts by weight for 100 parts by weight of said transparent organic polymer substance, wherein said transparent organic polymer substance comprises an acrylic-based resin, wherein said acrylic-based resin comprises an acrylic-based resin synthesized at least from a (meth) acrylic acid alkyl ester of 70–100 wt % and a monoethylene unsaturated monomer of 0–30 wt %, the monoethylene unsaturated monomer being capable of copolymerization with the (meth) acrylic acid alkyl ester, wherein the organized lamellar clay mineral includes an organic onium ion of 20–70 wt %, and wherein the adhesive face of the glass-break preventing layer comprises a removable adhesive face, wherein the removable adhesive face has a 90° peeling adhesive force of 0.7–10 N/25 mm width after 40 days at 80° C.
